There’s a specific torture test that separates serious modelers from impressive spec sheets. Run a unit through a bedroom jam at midnight, a Thursday rehearsal, a weekend festival stage, and a studio session where the recording engineer is watching every byte of latency — then talk about how well it handled the transition. Most units fail at least one of those scenarios. The Hotone Ampero II Stage, introduced at NAMM 2023, was designed from the ground up to pass all four.
Hotone is not the household name that Line 6 or Kemper are in the modeler space. That’s partly timing — the Changsha, Hunan-based company was only founded on 5 November 2012, making it one of the youngest players in the amp modeling game — and partly deliberate positioning. Hotone built its early reputation on the Skyline series of nano-sized single-effect stompboxes: tiny, surprisingly good, and priced for working musicians who couldn’t afford boutique. The Ampero series was the company’s move into the full-featured floor modeler territory. The Ampero II Stage is that move maturing into something genuinely competitive at the $700 price point — a unit that audiotechnology reviewer Preshan John described in June 2024 as representing “fantastic value” in a class where the usual choice is between affordability and quality.
What makes it interesting isn’t any single feature. It’s the combination: three DSP cores, ESS Sabre converters, Bluetooth control, 20 licensed Celestion IRs, five scenes per patch, an 8-in 8-out USB audio interface, and a 5-inch touchscreen, all in a unit that weighs under 4.2 pounds. At $699.99 new, it sits in the same bracket as the Boss ME-90 and the Line 6 POD Go, but with a feature count that rivals units $300 higher.
Hotone’s Road to the Ampero II Stage
To understand where the Ampero II Stage sits in the Hotone catalogue, you need to know where Hotone started. The company’s Skyline series — released from around 2013 onward — was a direct challenge to the idea that quality effects required real estate. Each Skyline unit was barely larger than a matchbox, but they delivered genuine tube amp tones, credible chorus, and usable reverb. Guitarists who discovered them in the YouTube demo era treated them as a budget secret.
The original Ampero appeared around 2018 as Hotone’s first serious floor modeler — built on their CDCM HD modeling technology and aimed squarely at the practice-plus-gig market. It offered a respectable feature set but was limited by its dual-DSP architecture and smaller screen. The Ampero II Stomp followed, refining the formula in a three-footswitch form factor that drew favorable comparisons with the Boss SY-200 and similar compact processors. Both of these laid the groundwork for what was coming.
The Ampero II Stage arrived at NAMM 2023 with a new engineering mandate. Hotone’s own engineering team summarized their goals in a statement to AudioTechnology magazine: “Guitarists often seek a balance between powerful core features, ease of portability, and expandability. The feedback from users and the team highlighted the need for a stage-aimed product that offers simplicity, more controllable footswitches and knobs, additional signal routing options, and a brighter, more straightforward interface.” In other words, they listened to what players wanted from the Ampero II Stomp and scaled it up intelligently rather than just bolting on more hardware.
The result is the CDCM HD Gen 2 platform — the second generation of Hotone’s Custom Defined Circuit Modeling technology, now paired with F.I.R.E. (Finite Impulse Response Engine) cabinet simulation and a triple-core DSP that, in over a year of published reviews, nobody has managed to max out during live playing.
Hotone Ampero II Stage Specifications
Famous Players and Artist Connections
Let’s be direct about the famous-player landscape for the Hotone Ampero II Stage: it’s thin. The Equipboard database, as of mid-2026, documents one confirmed professional guitarist using the unit — Japanese instrumental guitarist Takayoshi Ohmura, who shared photo evidence of the Ampero II Stage on his Twitter feed. Ohmura, known for his solo instrumental work and Japanese TV appearances, is a credible endorser in his market but not a household name in the Western rock press.
Hotone does have a broader relationship with professional guitarists. The most prominent collaboration is with Cory Wong of Vulfpeck — but that connection is with the “Wong Press,” a signature expression pedal Hotone built with Wong, not with the Ampero II Stage itself. Wong’s gear choices are well-documented and his pedalboard doesn’t feature the Ampero II Stage as a primary unit. It’s worth being precise here: Hotone and Wong share a legitimate design collaboration, but it’s a different product line entirely.
This pattern — strong engineering, limited traditional artist endorsement — is structural for Hotone. The company doesn’t run the kind of formal touring-artist endorsement program that Line 6 or Kemper do. It sits in a price bracket where players like Guthrie Govan, John Petrucci, and Tim Henson typically occupy the Fractal or Neural DSP side of the market. That’s not a criticism — it reflects a deliberate choice to put budget into engineering and hardware rather than artist management. The Hotone community forum and YouTube modding scene are active and enthusiastic; the unit just hasn’t attracted the kind of big-name association that makes for easy press.
What this means in practice: the Ampero II Stage earns its reputation through what it does, not who plays it. In the $700 bracket, that may be the more honest metric anyway.
Tone Recipes and Settings
1. British Crunch — Stage to PA, No Amp
Target: thick, responsive crunch in the JTM45/Plexi tradition, running direct to FOH with the XLR balanced outputs.
- Amp model: one of the Hotone Plexi-type models (labeled variants of 1959 and JTM45 are both present)
- Cab: Greenback 4×12 IR — use a third-party Celestion G12M Greenback IR if possible for best results
- Mic emulation: SM57 at 45° off-axis, pulled back slightly
- Pre-amp gain: 55–65%, Master: 80%
- EQ: Bass 6, Mid 6, Treble 5, Presence 5
- Compressor: subtle, attack 40ms, release 100ms, ratio 3:1
- Reverb: small room, mix 12%
- Scene 1 (Rhythm): above settings. Scene 2 (Lead): add boost pedal model, gain +15%, mid +2dB
2. High-Gain Metal — 4CM with Real Amp
Target: using the Ampero II Stage effects loop integration for a 4-Cable Method rig with a tube head, keeping the real amp’s preamp in the chain.
- Chain template: Y>A/B (Chain A to amp input for preamp drive; Chain B through FX loop return)
- Pre-amp chain: Noise gate → Tubescreamer-type pedal (gain 20%, level 100%, tone 50%)
- FX loop: placed after preamp block, before power amp/cab
- Post chain: Chorus → Delay (tap-tempo quarter notes, 20% mix) → Reverb (plate, 18% mix)
- Cab simulation: OFF (using real speaker cabinet)
- Scene setup: Scene 1 clean patch from amp clean channel; Scene 2 drives amp into crunch; Scene 3 adds the tubescreamer for full gain boost
3. Clean Funk — Wah, Envelope, Direct
Target: the kind of clean Strat tone that players like Cory Wong or Guthrie Govan deploy — dynamic, touch-sensitive, cutting through a mix without amp volume.
- Amp model: Hotone Fender-style clean model (Twin Reverb / Deluxe Reverb reference)
- Cab: 1×12 Jensen-style IR (or Celestion Alnico Blue if available)
- Chain: Auto-Wah (sensitivity 60%, decay 180ms) → Comp (fast attack, 4:1) → Amp → Cab → Light Spring Reverb (mix 15%)
- EQ: treble up to 7, bass pulled back to 4, presence 6
- Assign auto-wah sensitivity to EXP pedal for manual wah control
- Use the stereo XLR outs to FOH — the twin output gives you a naturally wide clean spread
4. Ambient Drone — Infinite Sustain + Reverb Cascade
Target: Tim Henson/Polyphia-style cascading ambience; works for intro/outro sections, or looper-based soundscape building.
- Amp model: clean, low gain (8%), full bass, scooped mid
- Sustainer/freeze: use the Freeze effect if available, or set a long shimmer reverb (decay 8+ seconds, pitch +12)
- Layered chain: Compress → Pitch Shifter (12th + octave blend) → Modulated Delay (1/4 dotted, feedback 60%) → Hall Reverb (size 100%, mix 45%)
- Use the looper (60s stereo) to build layers — engage looper post-FX so each loop records the full wet signal
- Set Scenes to toggle between sparse (reverb-only) and full (pitch + delay + reverb) versions within the same patch
5. Studio DI Reference — Tracking Without Amp Noise
Target: clean, hum-free reference tone for tracking guitar parts that will be re-amped or heavily processed in the DAW.
- Use USB-C connection to DAW — the 8×8 interface at 44.1kHz or 88.2kHz is your recording path
- Input: E.GT mode (1MΩ impedance) for most single-coils and humbuckers; A.GT mode (4.7MΩ) if using high-impedance vintage pickups
- Chain: Tuner → Light noise gate (threshold -65dB, fast response) → Direct Out (no cab, no amp sim)
- Simultaneously: route XLR out WITH amp/cab sim to a second channel for reference monitoring
- The 8-in/8-out interface means you can record both the dry DI signal and the wet modeled signal simultaneously, giving you the re-amp option later
- Use the built-in Reamp function via USB for sending your DAW tracks back through the modeler
How It Compares
vs. Line 6 Helix Floor
The Line 6 Helix Floor sits at roughly $1,499 and is the established reference point for serious floor modelers. Its model count is comparable (over 100 amp models vs. 90+ on the Ampero II Stage), but the Helix’s real advantage is its 12-switch layout, larger community preset ecosystem, and the depth of its HX modeling. The Ampero II Stage cuts the price nearly in half while offering competitive specs in the core processing chain. The Helix is still the more complete live rig replacement; the Ampero II Stage is the more interesting value proposition for players who don’t need maximum footswitch real estate.
vs. Kemper Profiler Stage
The Kemper Profiler Stage at ~$1,499 operates on a fundamentally different philosophy: profiling real amplifiers rather than modeling them from mathematical descriptions. If you own great tube amps and want to capture them exactly, the Kemper does something the Ampero II Stage cannot. But the Ampero II Stage’s Tone Catch feature is a credible approximation — it captures the response of amps and pedals connected to its input and integrates those captures into the effects chain. It’s not the same as full Kemper profiling, but it’s a $699 answer to a $1,499 question for players who don’t need the full Kemper ecosystem.
vs. Fractal Audio FM9 Turbo
The Fractal Audio FM9 Turbo is a different league in terms of processing depth, model accuracy, and community maturity — at roughly $2,099, it should be. Tosin Abasi runs Fractal. If your priority is absolute tonal accuracy and you have the budget, the FM9 is the answer. If your priority is maximum features-per-dollar for live and studio use, the Ampero II Stage holds its own at one-third the price.
vs. Boss GT-1000
The Boss GT-1000 at $499 is the Ampero II Stage’s most direct value competitor. The GT-1000 has the Boss ecosystem, MDP (Multi-Dimensional Processing), and arguably better-known amp models. The Ampero II Stage counters with Bluetooth control, better screen real estate, Celestion-licensed IRs, and a dual-chain architecture that the GT-1000 can’t match. If you’re loyal to Boss’s sonic character and workflow, the GT-1000 wins on familiarity. If you’re open to the Hotone universe, the Ampero II Stage wins on flexibility.
vs. Mooer GE300
The Mooer GE300 at ~$489 new is the closest Chinese-market competitor at a similar price tier. The GE300 has a polyphonic synth engine that the Ampero II Stage lacks; the Ampero II Stage has better screen quality, the Scene function, Bluetooth control, and the Celestion IR license. Both units are excellent values; which one suits you depends on whether you want the synth (GE300) or the better stage workflow and connectivity (Ampero II Stage).
Buying Guide
The Ampero II Stage retails at $699.99 USD new on Sweetwater. Used units appear on Reverb starting around $350–450 depending on condition, with most traded examples in the $400–480 range. The used market for this unit is growing as the Ampero series continues to update — players upgrade when new firmware drops and sell their well-maintained units.
A few things to verify when buying used: first, confirm the firmware version. Hotone has maintained an active update schedule since launch; units running pre-1.2 firmware may be missing significant features including some amp models and the full Tone Catch workflow. The official Hotone support page maintains firmware binaries and update instructions. Second, confirm the AC adapter is included — the unit requires 9V center-negative at 1.4A minimum (9–18V range is acceptable), and a sub-spec power supply will cause noise or instability. Third, confirm the USB-C cable for computer connection is included or plan to buy a quality USB-C 2.0 cable — the interface function requires proper USB Audio 2.0 compliance and cheap cables introduce dropouts.
Sweetwater also sells bundles: the Ampero II Stage with a gig bag for $739.98, and a bundle with the Hotone Ampero Press expression pedal for $789.00. Given that the unit has no built-in expression pedal — the one con noted by every reviewer — the expression pedal bundle is worth considering if you anticipate needing real-time wah or volume control from a hardware pedal. The two EXP/CTRL jacks will accept any standard TRS expression pedal, so third-party options (Roland EV-5, Mission Engineering EP-1) work equally well.
No case is included with the standard unit. At 1895g and 301mm wide, the Ampero II Stage fits in most medium pedalboard bags alongside a few stompboxes. For fly gigs, it carries in a standard roller-bag guitar accessory pocket.
Ownership Notes
Several real-world workflow details don’t appear on the spec sheet. First, the PATCH and STOMP operating modes: in PATCH mode, the bottom five footswitches select patches from the current bank; in STOMP mode, those same switches control individual effects modules within a patch. The dedicated mode-switching footswitch handles the toggle. This is a clean system but it requires deliberate setup — you’ll want to map your most-used stomps before any live performance rather than discovering the defaults on stage.
Second, the Scene function is the standout live feature. Each of the five scenes within a patch can have completely different effect states, parameter values, and routing configurations — and switching between them is genuinely seamless, with no audio dropout. The smooth fade option adds a short crossfade between scenes that works well for cinematic moments but should be turned off for straight rhythm-to-lead switches where immediacy matters.
Third, the dual output routing requires understanding before you use it. The unbalanced ¼” outputs and balanced XLR outputs can carry different processing simultaneously — XLR with full cab simulation to FOH, ¼” without cab sim to a stage amp for monitoring, for example. This is the recommended Y-A/B configuration for live rigs with both a backline amp and a PA feed. Setting this up incorrectly (both outputs with cab sim into an amp) gives you the classic double-cabinet problem that ruins tone at volume.
Fourth, the Bluetooth MIDI feature is less documented than the audio Bluetooth, but it’s genuinely useful. Pairing Hotone’s Ampero Control MIDI footswitch via Bluetooth MIDI eliminates one floor cable entirely — you get an extended footswitch bank without the cable clutter. The pairing process is straightforward from the Bluetooth menu but needs to be done pre-show, not mid-set.
Fifth, the 8×8 USB interface running at 192kHz sample rate is real but rarely necessary for guitar tracking. At 44.1 or 48kHz the interface performs without issues on both Mac and Windows (Windows requires the Hotone ASIO driver from the support page). The Reamp function — sending a DAW track back through the modeler for re-processing — works over USB without extra hardware and is a genuine time-saver in studio sessions.
Sixth, the factory presets are a starting point, not a destination. Hotone’s community preset sharing platform has grown substantially since the unit launched; downloading presets from the Hotone community or from the Editor software is the fastest way to understand what the unit is capable of before building from scratch. Most experienced users recommend loading third-party Celestion IRs into the 50 user slots immediately — the 20 factory Celestion IRs are good, but a variety of mic positions and vintage cab captures will expand your tonal palette considerably.
Frequently Asked Questions
Does the Hotone Ampero II Stage have a built-in expression pedal?
No. This is the most commonly cited limitation in reviews. The unit has two EXP/CTRL jacks that accept standard TRS expression pedals, and Hotone sells the Ampero Press as a companion unit. Any TRS-compatible expression pedal works — Roland EV-5, Mission Engineering EP-1, and similar units all function correctly. If you need hands-free volume or wah control in live use, plan to add an expression pedal to your budget.
Is the Ampero II Stage compatible with third-party IRs?
Yes. The unit accepts 24-bit/44.1kHz mono WAV files at 1024 or 2048 sampling points. You have 50 user IR slots. The 2048-point resolution (double the original Ampero II Stomp) provides noticeably better transient definition compared to shorter IR captures. Most commercially available IR packs from producers like Celestion Digital, OwnHammer, or Cab Lab are compatible after format checking — verify WAV format and sample rate before loading.
What is Tone Catch and how does it compare to Kemper profiling?
Tone Catch captures the frequency response of an amplifier or pedal plugged into the Ampero II Stage’s input and creates a profile that integrates into the effects chain. It’s a simplified capture process that runs entirely on-device in a few seconds. Kemper profiling is a more sophisticated process that captures the full dynamic response of an amplifier under different gain states and produces a more accurate reproduction, particularly at the edges of the dynamic range. Tone Catch is useful for capturing a favourite amp’s basic character; Kemper profiling is more accurate for high-fidelity amp cloning. The Tone Catch results can be shared with the Hotone community for other users to download.
Can I use the Ampero II Stage as a standalone audio interface?
Yes. The USB-C connection presents the unit as an 8-in, 8-out USB Audio 2.0 interface to Mac and Windows. Sample rates of 44.1, 48, 88.2, 96, 176.4, and 192kHz are all supported. On Windows, install the Hotone Generic USB ASIO driver for low-latency performance — without it, Windows defaults to WDM/KS which introduces measurable latency. Mac requires no additional driver. The interface supports simultaneous monitoring of both the direct (dry) guitar signal and the processed (wet) signal, which enables clean re-amping workflows in DAW sessions.
How does the Scene function work in a live set?
Each patch holds five Scenes. A Scene is a snapshot of the patch’s effect states, parameter values, and routing at a given moment. Switching between Scenes within a patch is instantaneous and dropouts-free — the reverb tail from Scene 1 continues naturally into Scene 2, including the fade option. This means you can build an entire song’s tonal arc into a single patch (clean intro, rhythm crunch, pre-chorus swell, lead solo, outro ambient) and navigate it with one footswitch. In Stomp mode, you can also manually toggle individual effects on or off within a Scene. The Scene + Stomp combination gives you more live flexibility than many units at twice the price.
What’s the difference between the Ampero II Stage and the Ampero II Stomp?
The Ampero II Stomp is a compact three-footswitch unit with a 4-inch screen, designed for pedal-board integration and practice use. The Ampero II Stage adds: five more assignable footswitches (eight total vs. three), a larger 5-inch touchscreen, XLR balanced stereo outputs (the Stomp has only ¼” unbalanced), the Bluetooth module (the Stomp is Bluetooth-free), the Scene function with five scenes per patch, and the dual-output routing architecture for simultaneous PA + stage amp feeds. The processing engine — triple-core DSP, ESS Sabre converters, CDCM HD Gen 2 — is shared between both units. Effects and presets are cross-compatible. The Stage is the full live rig; the Stomp is the pedalboard insert.
Does the Ampero II Stage support MIDI clock synchronization?
Yes. The unit has MIDI in and MIDI out on ⅛” TRS jacks (compatible with standard 5-pin DIN via the included adapter). MIDI clock, program change, and control change messages are all supported. Bluetooth MIDI is also available, enabling wireless sync with DAWs, loopers, or controller units without floor cables. MIDI program changes can trigger patch changes on the Ampero II Stage from an external controller, and the unit can send MIDI to downstream devices to switch amp channels or trigger other processors in a complex rig.
Is the Hotone Ampero II Stage good for bass?
Yes, with qualifications. The unit includes bass-specific amp models and the input modes include a LINE setting suitable for active bass pickups. The dual-output architecture — XLR to FOH with cab sim, ¼” to stage bass amp without cab sim — is a standard pro-bass stage configuration. Bass players who run direct-to-PA setups with stage monitoring amps will find the routing options practical. The effect library includes bass-appropriate dynamics, EQ, and filter models. It’s not a dedicated bass unit, but it handles bass input with more flexibility than most guitar-focused floor modelers.
