Every modelling amp will tell you it sounds like a Marshall, a Fender and a Vox. The claims are everywhere — algorithms, impulse responses, digital recreations of classic circuits baked into a chip. The Boss Nextone Stage does something different. When you spin its output-stage selector from 6V6 to EL34, the amp physically rewires its analogue Class A/B output circuitry. There is no DSP doing an impression. The circuit changes. That is not a marketing claim — it is the core engineering proposition of the Nextone range, and it explains why players who have played tube amps for decades consistently reach for words like “scarily realistic” when they plug into one.
The Nextone Stage is a 40-watt, 1×12 solid-state combo with four selectable tube-type emulations, two channels, built-in delay and reverb, power scaling down to 0.5W, and a free editor app that unlocks a deeper layer of customisation underneath the traditional knob layout on the front panel. It sits between Boss’s own Katana range (more effects, lower price) and the Roland Blues Cube Artist (plywood cabinet, purer tweed focus) in a narrower niche: players who want convincing tube-amp feel without the maintenance, the weight penalty of a real valve output stage, or the menu-diving of a full modelling platform.
That niche turned out to be real. The Nextone Stage launched in 2019 and has stayed in Boss’s catalogue ever since — a quiet, reliable seller to the serious working guitarist who wants to plug a guitar and a few pedals in and sound like themselves.
Where the Nextone Fits in the Boss/Roland Family Tree
Roland — Boss’s parent company — has been building guitar amplifiers longer than most players have been alive. The JC-120 Jazz Chorus arrived in 1975 and has never left production. The original CUBE series launched in 1978. The Blues Cube, a more tonally focused solid-state tweed-voiced amp, was completely redesigned in 2014 using Roland’s Tube Logic platform. Then in 2016, Roland chose the Boss brand for the Katana range — a digital modelling amp with broad effects coverage and a price point that immediately disrupted the modelling market.
The Nextone range, announced in 2018 and widely available by 2019, occupies different ground than any of those. It inherits the Tube Logic analogue approach of the Blues Cube — specifically, the idea that Tube Logic physically reconfigures analogue solid-state components to replicate the dynamic behaviour of a valve output stage — but extends it across four classic tube types rather than the Blues Cube’s single tweed character. Boss also added a delay and USB recording interface, and dropped the price compared to the Blues Cube equivalents.
Two models make up the Nextone line: the Nextone Stage (40W, the subject of this article) and the Nextone Artist (80W). Both share the same fundamental architecture. The Stage is the smaller and more practical gigging proposition for most club and pub environments.
The Engineering Core: Why Tube Logic Is Different
Most solid-state modelling amps use digital signal processing throughout: a computer models the complete behaviour of a target amplifier and outputs that signal through a clean, neutral solid-state power amp. The modelling is comprehensive, the result can be impressive, but the final link in the chain — the power section — is fundamentally different from a valve output stage. The interactive relationship between an output transformer, the valve’s non-linear clipping characteristics, the power supply sag under load, and the speaker’s back-EMF pushing back on the circuit — all of that is missing.
Roland’s Tube Logic approach targets that specific gap. The output section uses digitally controlled analogue solid-state components — not DSP processing — configured to replicate the dynamic response and clipping behaviour of four specific output tube configurations. When you select a tube type on the front panel, you are selecting a different analogue circuit path, not loading a different software profile. The result is that the amp responds to picking dynamics, to volume knob adjustments on the guitar, and to the interaction between preamp drive level and output stage loading in ways that digital modelling amps typically cannot replicate.
Sound on Sound’s Paul White, reviewing the amp at launch (March 2019), was explicit about this: “It’s all very different from the various modelling amps of other manufacturers that do all the emulation with DSP and then feed the result through a clean power amp — no doubt this is one reason these amps get so much closer to a true valve-amp feel.”
MusicRadar’s Nick Guppy, reviewing in July 2019, reached the same conclusion from the other direction: “The Nextone Stage sounds scarily realistic, with bouncy dynamic cleans and fat, touch-sensitive tweedy overdrives.”
The Four Output Stage Types
The output stage selector is a four-position rotary knob on the far right of the control panel. Here is what each position delivers and where those tube types historically appeared:
6V6 — The sweet spot of low-wattage American amplifiers. The 6V6 is the tube inside Fender’s Champ, Deluxe Reverb and Vibrolux, and its character is often described as compressed, vocal, and warm. On the Nextone Stage it delivers the least headroom of the four options and breaks up earliest at a given volume — an advantage for blues and roots players who want natural power-amp compression at living-room levels. Think small-club Fender territory: pick dynamics that bloom and sustain rather than cut.
6L6 — The higher-headroom American equivalent. Fender’s Twin Reverb and the original Bassman used 6L6s, and the character is muscular mid-range, extended clean headroom, and a tighter low end. On the Nextone Stage this is the setting for big, open cleans that stay clean longer under hard picking. A telecaster through a 6L6 Nextone Stage into a clean room is a convincingly good Fender simulation — not an impression of one.
EL84 — Cross the Atlantic and the circuit changes character entirely. The EL84 is the tube in Vox AC15 and AC30 amplifiers, configured in Class A in those designs, and its defining characteristic is a chiming, glassy high-frequency content that adds presence and sparkle to single-coil pickups. On the Nextone Stage the EL84 setting has the most distinctive top end of the four options, breaks up sweetly without muddying the low mids, and is the natural home for jangly rhythm work and indie clean tones. MusicRadar noted the Vox character specifically: cycling through the tube types, “you can certainly hear classic Plexi, Tweed, Blackface and Vox characteristics.”
EL34 — Marshall’s tube of choice from the 1960s onward. The EL34 powered every major Marshall stack from the early Plexi heads through the JCM800 and JCM900 ranges. On the Nextone Stage it delivers the most aggressive midrange voicing and the clearest path toward classic British crunch. At higher gain settings on the Lead channel, this is where you hear the Nextone most convincingly evoking a pushed British stack.
One honest caveat worth stating clearly: as MusicRadar’s review noted, the differences between tube types become subtler as gain increases. At high gain settings, the Nextone Stage’s preamp saturation starts to dominate and the output stage character becomes harder to distinguish. The four modes are most distinctly audible on the clean channel and at lower overdrive levels — which is exactly where output stage character matters most on real tube amps too. If you play primarily high-gain metal with the gain knob past 3 o’clock, the Nextone Stage is not primarily selling itself on tube-type versatility. If you play clean, edge-of-breakup or moderate crunch tones, the selector is genuinely useful.
Controls and Features
The front panel layout is deliberately traditional: no LCD, no menus, no banks to scroll through. Clean Volume on the left, then Lead Gain and Lead Volume, then the shared Bass/Mid/Treble EQ with a Presence knob, then two knobs for Delay level and Reverb level with a tap-tempo button and delay on/off switch, then the Master Volume, and finally the power-stage type selector and power control rotary. There are also two small buttons for Boost and Tone — the Boost adds crunch and the Tone switch adds brightness on the clean channel and warmth with a mid boost on the lead channel.
The amp’s two-channel architecture is simple. The clean channel has only a volume control. The lead channel has both gain and volume. They share the three-band EQ. There is one programmable custom preset, accessible by holding the Channel button for one second, which stores settings created in the Nextone Editor software.
Power scaling is a four-position rotary: Standby, 0.5W, Half (approximately 20W) and Max (40W). The 0.5W setting makes the Nextone Stage genuinely useful as a home recording tool — you can drive the output stage into its sweet spot at bedroom volume and mic the speaker, or use the speaker-emulated output directly.
Connectivity on the rear panel includes a speaker-emulated line out, a headphones/recording out with three selectable “Air Feel” cabinet simulation options (accessible via the editor app), a USB socket that functions as a two-channel recording interface (capturing both mic-emulated and clean DI signals simultaneously), an effects loop configurable as series or parallel, and two footswitch jacks. Speaker output jacks are mounted on the underside of the chassis and allow up to two external cabinets to be connected, as long as the combined load stays at or above 8Ω.
The optional GA-FC foot controller (sold separately) connects via a TRS cable to the delay jack and provides six-button control over channel selection, tone, boost, effects loop and delay on/off, plus two additional jacks for a tap-tempo switch and a master volume expression pedal. If you prefer a simpler setup, Boss’s FS-series latching footswitches work via the dedicated footswitch jacks. The GA-FC is the more capable option for a full live rig; the FS switches are sufficient for channel switching at a gig.
The Nextone Editor App
The free Mac/Windows Nextone Editor app unlocks a deeper layer of customisation not available from the front panel. Within the app you can adjust bias point, power supply sag, additional parametric EQ (including two fully parametric mid-range bands), tone stack type, boost voicing (or swap the boost for a compressor), delay type and reverb type. You can also swap the onboard delay for a tremolo in the custom preset. The app makes it possible to have different power tube types assigned to the clean and lead channels within that custom setting.
Any settings built in the editor can be saved to the amp’s single custom preset, accessed by a one-second hold of the Channel button. The app supports saving as many editor configurations as you want on your computer; you can only have one loaded into the amp at a time, and switching to or from the custom preset is not instant — which means mid-song switching is not practical. If your live rig requires switching between delay and tremolo on the fly, note that this is only available between the normal mode (delay) and the custom preset (tremolo) via that press-and-hold move. There is no front-panel way to switch it.
Paul White’s SOS review specifically flagged this as a missed opportunity: the tremolo/delay swap and the delay feedback level could reasonably have been made accessible on the front panel via familiar button-hold combinations. It is a real ergonomic limitation if tremolo is a primary effect in your playing.
Cabinet and Build
The Nextone Stage uses a particle-board cabinet rather than the plywood used in the Roland Blues Cube series. This is the most discussed physical difference between the two amp families. Particle board is denser and less acoustically resonant than plywood, which tends to result in a slightly less warm cabinet contribution to the overall tone. Paul White’s SOS review noted a direct comparison: “In a direct shootout, I felt the Blues Cube Hot and Stage models seemed slightly warmer-sounding and somehow more ‘lively’.” He attributed this to the cabinet or speaker, acknowledging that more editor tweaking on the Nextone might close the gap.
The particle board also makes the Nextone heavier than comparable plywood cabinets — a real consideration for working musicians moving gear weekly. The finish is black textured vinyl with black plastic corners and silver-trimmed grey-striped grille cloth, giving the amp a clean, professional stage look. The Boss badge sits centrally on the grille.
The custom 12-inch speaker appears to be a different unit from the Blues Cube’s V-12 speaker. Boss does not publish the speaker’s detailed specification separately.
Famous Players: An Honest Account
Equipboard’s metadata for the Boss Nextone Stage states “2 pro artists use it.” Neither is a household name in the context of classic rock guitar. The Nextone Stage launched in 2019 without a signature model, without a high-profile endorsement campaign, and without the kind of artist tie-in that the Blues Cube Artist line developed through its Tone Capsule partnership with players like Eric Johnson and Robben Ford. Johnson, who is in this project’s guitarist database (files: eric-johnson.html and s4-015-eric-johnson-gear-guide.html), co-developed the Blues Cube TC-EJ Tone Capsule — that is a Blues Cube story, not a Nextone one, and the distinction matters.
The absence of a famous-player angle is not unusual for a solid-state gigging workhorse in the $499–$649 bracket, and it does not reflect on the amp’s quality. The Katana 50 Gen 3 at this same price point has exactly one Equipboard-confirmed pro in its database (Mac DeMarco, indie/lo-fi). The Nextone Stage occupies a similar structural position: an amp built for serious working guitarists who do not have a tech, a tour bus or a sponsor relationship with an amp manufacturer.
The broader context is that the players most associated with the sound the Nextone Stage aims at — Angus Young (EL34/Marshall), Jimi Hendrix (Marshall/Uni-Vibe), Stevie Ray Vaughan (Dumble/Vibroverb) — play or played actual tube amps, and their tones are what the Nextone Stage’s four emulation modes reference. The amp is designed to give a working guitarist access to those sonic territories without the valve bill or the maintenance anxiety. The famous players are in the genealogy of the sounds, not in the endorsement history of this specific box.
Tone Recipes and Settings
Recipe 1: 6V6 American Blues Clean — SRV Warm Neck Tone
Output stage: 6V6. Channel: Clean. Clean Volume at 12 o’clock. Bass 12, Mid 1 o’clock, Treble 11, Presence 9. Master Volume set for room — 0.5W at home, Half power at a small gig. No boost, no tone switch. A single-coil neck pickup humming at the other end. The 6V6’s natural compression turns pick attack into bloom — less initial transient, more sustain — which is the exact behaviour Stevie Ray Vaughan’s heavy-gauge strings and Fender Stratocasters exploited. Roll the guitar’s volume back to 7 for a cleaner, glassier version; push it to 10 for the edge of power-amp saturation. No pedals required.
Recipe 2: EL84 Vox-Style Jangle — Indie Rhythm
Output stage: EL84. Channel: Clean. Tone switch engaged (brightens clean channel). Clean Volume at 2 o’clock, Bass 10, Mid 11, Treble 2 o’clock, Presence 1 o’clock, Master at pub gig level. The EL84’s chime and glassy top end flatter open-position chords and barre chords equally. Add the onboard reverb at about 9 o’clock for a room ambience. This is the closest the Nextone Stage gets to a Vox AC30 without owning one. A semi-hollow guitar with P-90s or mini-humbuckers locks this in.
Recipe 3: EL34 British Crunch — Classic Rock Rhythm
Output stage: EL34. Channel: Lead. Gain at 10 o’clock, Lead Volume at 12, Bass 12, Mid 1 o’clock, Treble 12, Presence 1 o’clock. Boost engaged. Master at full power for the gig. Place a Ibanez TS9 Tube Screamer in the effects loop with its level boosted, tone flat, drive at zero — this tightens the low end and pushes the midrange of the EL34’s natural voicing further forward. The result approximates the crunch of a pushed Marshall JCM800 at a fraction of the volume and maintenance cost. A humbucker-equipped guitar, bridge pickup, light pick attack for rhythm, hard attack for fills.
Recipe 4: 6L6 Country Clean — Telecaster Snap
Output stage: 6L6. Channel: Clean. Clean Volume at 12, Bass 9 o’clock, Mid 10, Treble 2 o’clock, Presence 2 o’clock, Master at minimum needed to fill the room. No boost. The 6L6’s extended headroom means the amp stays clean even with aggressive picking — which is exactly the right canvas for a telecaster’s bridge pickup cutting through a track. Add the onboard delay at about 8 o’clock (light slap-back) and the reverb at 9. Nashville picking or chicken-pickin’ translates cleanly without the pick attack collapsing into flab. Roll tone on the guitar back slightly for a warmer rhythm tone on the same patch.
Recipe 5: 0.5W Studio Session — Home Recording into a Mic
Output stage: whichever suits the session. Power control: 0.5W. Channel: Lead at moderate gain. Place a dynamic mic (SM57 or equivalent) close-miked on the speaker — offset from the cap slightly for a warmer tone. Choose “Air Feel” cabinet option 2 or 3 in the Nextone Editor for the emulated output if you want a blended signal in your DAW alongside the mic. The 0.5W setting genuinely drives the output stage of the Nextone Stage, not just attenuates a clean signal — this is the Tube Logic architecture doing its job. The recorded result is dimensionally more realistic than DI-into-a-plugin for players who care about the physical room behaviour of an amp and speaker.
How the Nextone Stage Compares
vs Boss Katana Artist Gen 3
The Boss Katana Artist Gen 3 is a more expensive amp with six amp characters (including the Acoustic and Brown voicings), a Waza G12W speaker, Bloom switch, MIDI In, Power Amp In, and three speaker output jacks — plus full access to Boss Tone Studio for downloading and sharing patches. If effects variety and patch recallability matter more than output-stage realism, the Katana Artist is the better choice. If you want fewer amp voices but more convincing tube-like response in each of them, the Nextone Stage has the more focused engineering argument.
vs Boss Katana-100 Gen 3
The Katana-100 Gen 3 costs less than the Nextone Stage (Sweetwater $449.99 vs approximately $499–$549 for the Nextone) and offers the hardware Contour and Amp Resonance switches, standard effects loop, and full Boss Tone Studio access. For the player who primarily needs a reliable 100W gigging amp with broad amp-voicing options, the Katana-100 Gen 3 arguably delivers more value per dollar. The Nextone Stage justifies its premium specifically through its physical output-stage reconfiguration and the resulting playing feel — a distinction that matters more to some players than others.
vs Roland Blues Cube Artist
The Roland Blues Cube Artist shares the same Tube Logic DNA as the Nextone Stage but is focused exclusively on a 1950s tweed voicing. Its plywood cabinet and the Roland V-12 speaker give it a slightly warmer acoustic character than the Nextone Stage’s particle-board construction — Paul White’s SOS review specifically heard the Blues Cube as “slightly warmer-sounding and more lively” in a direct comparison. The Blues Cube also supports the Tone Capsule plug-in system, giving access to artist-collaborated circuit voicings. The Nextone Stage has more built-in output-stage variety than the Blues Cube and adds the delay/USB interface. If you want one circuit pushed as warm and alive as possible, the Blues Cube; if you want the tube-type flexibility, the Nextone Stage.
vs Fender Deluxe Reverb
The Fender Deluxe Reverb runs on real 6V6 output tubes and a 5AR4 rectifier, weighs 22kg, requires periodic tube replacement and biasing, and cannot power-scale below its full 22W without an external attenuator. At stage volume it sounds like a Fender Deluxe Reverb — which is incomparably good. At bedroom volume it sounds thin and unrewarding because the output stage is not loaded correctly. The Nextone Stage costs less than a reissue Deluxe Reverb, weighs less, requires no maintenance, and at 0.5W genuinely drives its output stage into its sweet spot in a home setting. For the pub and club musician who gigs two nights a week and records at home, the Nextone Stage is a more practical instrument.
vs Quilter Aviator Cub
The Quilter Aviator Cub uses Class D power amplification and a different tube-feel philosophy — continuous analogue voicing rather than discrete tube-type emulation. It is lighter and typically slightly cheaper than the Nextone Stage. Players often describe the Quilter as more immediately transparent and pedal-friendly, while the Nextone Stage has more inherent character from its output stage. Neither is wrong; they represent different engineering answers to the same question.
Buying Guide
The Nextone Stage launched at $499.99 in the United States (Sound on Sound, March 2019) and has drifted slightly higher at some retailers since. Current street prices vary between approximately $499 and $649 depending on retailer and availability. The used market has settled around $350–$450 for clean examples — the Nextone Stage is a reliable amp with no tubes to fail, which means used examples in good cosmetic condition are generally in full working order.
The companion Nextone Artist (80W, same tube-type options, same Tube Logic approach) runs approximately $150–$200 more new. For most club and pub gigging contexts, the 40W Stage is sufficient — even at half power (approximately 20W) it produces more stage volume than most small venues require. The 0.5W setting is the home-practice and recording mode; the half-power setting covers the majority of small-to-medium live applications.
What you are not getting compared to the Katana range: MIDI control, access to Boss Tone Studio’s effect library, patch banking beyond the single custom preset, the Bluetooth audio option (via dongle), or the amp-type variety of six characters versus four tube emulations. If those features are on your requirements list, the Katana is the better fit. If they are not, and you are specifically shopping for solid-state tube feel, the Nextone Stage is among the most honest attempts at that goal available in this price bracket.
The GA-FC foot controller is effectively necessary for gigging use if you want to switch channels and control effects without bending down to the amp. Budget for it alongside the amp purchase — it is not included in the box.
Ownership Notes
The Nextone Stage is a set-and-forget amp in the best sense. No tubes to retube, no biasing, no standby ritual, no concern about power-tube matching. Plug it in, let it warm for thirty seconds, and it is ready. The full-power 40W output stage runs fully solid-state Class A/B, which means no inrush thermal concerns common with valve amps.
The Nextone Editor app requires a USB connection to communicate with the amp and a Mac or Windows computer to run. It is a one-time setup activity for most players — configure your custom preset, load it to the amp, disconnect and gig. The app does not need to be running at the venue. Keep the editor installer backed up so you can restore your custom preset if needed after a factory reset.
The effects loop is configurable as series or parallel through the editor app — not from the front panel. Decide your preferred routing before your first gig and set it in the editor. Series is standard for most effects chains; parallel works best for time-based effects mixed at a lower level.
The USB recording output captures two tracks simultaneously: the speaker-emulated signal (with your chosen Air Feel cab simulation) and the clean DI guitar signal. This means every recording session is non-destructive — if the mic emulation is not to your taste in the mix, you have the clean DI as a re-amp source. Combined with the 0.5W power setting, the Nextone Stage works as a competent recording interface without requiring an additional DI box or audio interface for straightforward single-guitar tracking.
Frequently Asked Questions
Is the Boss Nextone Stage actually analogue?
The output stage is analogue — digitally controlled analogue solid-state components that physically reconfigure when you change tube types. The preamp section and effects (delay, reverb) involve digital processing. The result is a hybrid: analogue output behaviour, digital convenience features. This is the key distinction from all-DSP modelling amps and the main reason for the Nextone Stage’s playing feel.
How loud is the Nextone Stage at 0.5W?
Quiet enough for late-night home use without waking the house, but still audible in a room without headphones. Think slightly above a loud acoustic guitar. The 0.5W setting is not silent-practice quiet — it genuinely powers the speaker. For completely silent practice, use the headphone/recording output, which bypasses the speaker entirely.
Can I use the Nextone Stage with headphones?
Yes. The phones/rec output on the rear panel accepts a standard 6.35mm jack and includes the speaker-emulated signal with Air Feel cab simulation (selectable in the editor app). This bypasses the speaker, making it suitable for silent home practice.
What is the difference between the Nextone Stage and the Nextone Artist?
The Nextone Artist is the 80W version. Same Tube Logic technology, same four tube-type options, same control layout and editor app. The Stage is 40W in a slightly smaller cabinet; the Artist is 80W with more headroom for larger stages. Both have the same semi-open-back particle-board construction and custom 12-inch speaker (though potentially a different specific driver model).
Does the Nextone Stage work well with pedals?
Yes — this is its natural habitat for many players. Paul White’s SOS review specifically tested it with an OCD overdrive and found it “worked perfectly well for lifting a slightly jangly clean tone into classic rock territory.” The Lead channel at low gain settings gives pedals plenty of headroom to shape the final tone, while the EL34 or 6V6 output stage adds natural output-stage character underneath whatever the pedal is doing. The effects loop also accepts external effects at line level.
Can I run the Nextone Stage through an external cabinet?
Yes. Speaker output jacks on the underside of the chassis support up to two external cabinets, as long as the combined impedance load does not fall below 8Ω. You can disconnect the internal speaker if you prefer to run entirely through an external cab.
Is the GA-FC foot controller included with the Nextone Stage?
No. The GA-FC is sold separately. The amp includes standard latching footswitch jack connectivity, so Boss FS-series footswitches work without the GA-FC, but with limited functionality (channel select and a second function, no tap tempo expression or effects loop control). Budget for the GA-FC if live gigging with channel switching and effects control is a priority.
How many patches can the Nextone Stage store?
One custom preset, created in the Nextone Editor app and loaded to the amp via USB. The amp also has its standard operating mode (normal mode, without editor customisation). You can save as many editor configurations as you want on your computer, but only one can be active in the amp at a time. For players who need per-song patch recall, the Katana range with Tone Studio is a better fit.
