The Wah That Refused to Be Replaced: Inside the Ibanez WH10V3

There is a moment on “Give It Away” — those first slashing wah-filtered chords before the verse kicks in — where the sound is so distinctively creamy, so wide-sweeping and filter-like, that it doesn’t quite sound like any other wah pedal on the market. That’s not a Cry Baby. That’s not a Vox. That’s an Ibanez WH10, and the guitarist using it is John Frusciante, and he told Vintage Guitar magazine in 2009 exactly why he’s never replaced it: “It is my standard wah since Blood Sugar Sex Magik. I don’t think there’s a better wah. When we were making Stadium Arcadium, there was so much wah I figured I’d use a variety of pedals and there wasn’t one that came close to the Ibanez.”

That endorsement, from one of the most analytically gear-obsessed guitarists of his generation, explains why the WH10 has held its cult status for three decades — and why Ibanez, timing it precisely with Frusciante’s return to the Red Hot Chili Peppers in December 2019, launched the WH10V3. The third version of the pedal retains everything that made the original special and adds exactly the hardware improvements that players had been waiting for: selectable true bypass, a depth control, and a die-cast metal housing in place of the original’s plastic shell.

The WH10V3 occupies a genuinely unusual position in the wah market. Where the Dunlop Cry Baby family dominates the industry through sheer market share and inductor-based voicing, the WH10V3 does something architecturally different. It uses a multiple feedback op-amp circuit — the first wah pedal ever built on that topology — which produces a frequency sweep with markedly different character. Wider, smoother, more filter-like in certain modes, and significantly more useful for bass applications. If you’ve spent years wondering why your Cry Baby never quite sounds like a particular RHCP record, this is why.

A Brief History of an Unlikely Icon

Ibanez introduced the original WH10 in 1987 as part of its effect pedal lineup. The design was modest in presentation — a standard wah rocker in a plastic housing — but the circuit underneath was genuinely novel. Rather than building around an inductor coil (the standard approach used by Vox, Dunlop, and most of the industry), Ibanez engineer designed the WH10 around a multiple feedback operational amplifier topology. The result was a frequency sweep that behaves differently from inductor-based wahs: less pronounced mid-peak, wider frequency range, and what many players describe as a more “liquid” or “envelope filter-like” character at the bottom of the sweep range.

For most of its first decade the WH10 was a niche product. Then Blood Sugar Sex Magik arrived in 1991 and Frusciante’s playing brought the pedal into sharp focus for anyone paying attention to what was happening in his rig. The WH10 can be heard across the album — on “Give It Away,” “Suck My Kiss,” “Breaking the Girl,” and others — in a style that made the pedal’s character unmistakable to anyone who later tried to replicate those sounds on a standard Cry Baby and found themselves frustrated by the results.

After the original run ended, the WH10 became a collector’s item — vintage V1 units in good condition trading at significant premiums. Ibanez responded with the WH10V2 reissue in the early 2000s, which brought the circuit back but retained the plastic housing and buffered bypass of the original. The V2 served players who needed the sound but couldn’t source or afford original V1 units.

The WH10V3 arrived in December 2019, and the timing was pointed. Frusciante’s return to the Red Hot Chili Peppers was announced that same month, and Guitar World covered the pedal’s release under the headline “Not only is John Frusciante back, but his favorite wah pedal is, too.” Whether the launch was coordinated with Ibanez is speculation, but the synchronicity underlined what the WH10V3 is, commercially and musically: the definitive modern version of the pedal that defined Frusciante’s tone, built to his era’s specifications.

What the WH10V3 Actually Is: Circuit and Architecture

The WH10V3’s defining characteristic is its multiple feedback op-amp circuit. In a conventional inductor-based wah — the Cry Baby GCB95, the Vox V847, virtually everything else in the mainstream market — the wah effect is produced by a resonant peak that sweeps through the frequency spectrum as you rock the pedal. The inductor creates a sharp, pronounced mid-frequency spike with clear Q (resonance). Players who grew up on Hendrix, Clapton, or Slash have been hearing this specific character for decades and it’s deeply embedded in the cultural vocabulary of what a wah pedal “should” sound like.

The WH10V3’s op-amp circuit doesn’t behave the same way. The peak is broader, less pronounced, and the sweep covers more frequency territory per unit of pedal travel. The bass mode (175Hz–1.1kHz) isn’t just for bass guitar — Frusciante famously used the WH10 in bass mode on guitar to get an envelope filter quality rather than a traditional wah character. The guitar mode (350Hz–2.2kHz) is the standard playing range, covering the full frequency sweep that guitar lines need, but still with that wider, smoother character compared to the Cry Baby family.

The V3 adds three significant hardware upgrades over the V1 and V2. First, the housing is now die-cast aluminum alloy rather than plastic — a genuine durability upgrade for live use. Second, the bypass is now switchable: a lever switch on the unit lets you choose between buffered bypass (the original V1/V2 mode) and true bypass. This matters for pedalboard design: players with long cable runs or no buffers elsewhere may prefer buffered bypass; players with other buffers on their board or who want zero signal interference when bypassed will prefer true bypass. Third, the depth control knob on the side panel lets you dial in how intense the wah effect is, from subtle filtering to full dramatic sweep — a control the original never offered.

Famous Players: Honest Assessment

The Ibanez WH10 has a documented player base that is smaller but more intensely devoted than the Cry Baby family. Before examining who actually used it, it’s worth addressing the roster of names that frequently appears in wah pedal discussions generally — because several famous guitarists associated with the wah category specifically are not WH10 users.

Jimi Hendrix used the Vox Clyde McCoy wah and Cry Baby wah. He died in 1970. The Ibanez WH10 was released in 1987. Any association between Hendrix and the WH10 is a chronological impossibility — the pedal did not exist during his lifetime.

Slash is associated with the Dunlop Cry Baby 535Q, which he has used and promoted extensively. His wah tone on Guns N’ Roses recordings is inductor-based, not op-amp based. No primary source documents Slash using an Ibanez WH10.

Kirk Hammett uses the Dunlop Cry Baby From Hell (KH95), a signature model built around an inductor circuit. His wah appears throughout Metallica’s catalog. No confirmed source documents a WH10 in his rig.

Jerry Cantrell has a signature wah model — the Dunlop JC95 Jerry Cantrell Signature Cry Baby, also inductor-based. He has discussed his wah preferences in multiple interviews and the WH10 is not mentioned. His Jerry Cantrell Gear Guide documents his actual wah use.

Tom Morello is primarily known for using the Dunlop Cry Baby 535Q wah in his various technical applications. His wah approach is well-documented and the WH10 does not appear in confirmed accounts of his rig.

These are all legitimate wah players — but their wah of choice is the Cry Baby family, not the Ibanez WH10. The WH10 family has its own distinct canonical user.

John Frusciante — Confirmed, Primary Source

John Frusciante is the guitarist whose use of the Ibanez WH10 is not only confirmed but defined the pedal’s cultural status. The primary source is a 2009 interview in Vintage Guitar magazine, in which Frusciante stated: “It is my standard wah since Blood Sugar Sex Magik. I don’t think there’s a better wah. When we were making Stadium Arcadium, there was so much wah I figured I’d use a variety of pedals and there wasn’t one that came close to the Ibanez. I want something that when I put it in one position, one note is going to feed back, and when I put it in another position, another note is going to feed back. You just have more variation with the Ibanez because there’s a wider frequency range.”

Frusciante’s use of the WH10 is documented across more than fifteen years of RHCP recordings and live footage. On Blood Sugar Sex Magik (1991) the pedal appears on tracks including “Give It Away,” “Suck My Kiss,” and “Breaking the Girl.” It continued through Californication (1999), By the Way (2002), and Stadium Arcadium (2006) — albums that collectively represent some of the most widely analyzed wah tones in rock guitar history. He notably used the WH10 in bass mode on guitar to achieve the envelope filter quality on certain passages, treating the broader frequency response as a feature rather than a compromise.

The V3’s December 2019 launch coincided with Frusciante’s return to RHCP, and Guitar World explicitly framed the release in terms of his gear preferences. While Ibanez did not formally announce a signature relationship, the product launch timing and the company’s marketing language made the connection explicit.

Jonny Greenwood — Community-Documented, Not Primary Source Confirmed for WH10V3

Jonny Greenwood of Radiohead is frequently cited as a WH10 user in multiple gear documentation sources. Several rig rundown archives list the Ibanez WH10 in his pedalboard for the OK Computer era (1997), and Guitar.com’s published 1997 Radiohead rig diagram references it. However, the primary equipment documentation sources currently available do not list the WH10 in Greenwood’s confirmed gear — UberProAudio’s detailed Jonny Greenwood rig page does not include it, suggesting the connection may be partial, era-specific, or community-sourced rather than primary-interview confirmed. Jonny Greenwood’s full gear history documents his extensively unusual setup, which is based more around envelope filters, Digitech Whammy, and the Marshall ShredMaster than wah pedals as a consistent element. He is mentioned here because the WH10 connection appears in multiple respected gear archives, but readers should apply appropriate skepticism to the Greenwood-WH10 link given the absence of primary interview confirmation.

Equipboard Documentation

Equipboard’s WH10V3 listing documents two confirmed professional artists using the V3 specifically. John Frusciante is listed as the primary, consistent with his decades of use across WH10 versions. The second Equipboard-documented WH10V3 user is Jasper Harris, a contemporary guitarist whose WH10V3 use has been documented in community-uploaded rig photos. The WH10’s player base skews toward players specifically seeking Frusciante’s tone rather than a broad cross-section of wah users — which explains both the dedicated following and the relatively smaller confirmed roster compared to the Cry Baby family.

The Sound: What Makes This Pedal Different

Playing a WH10V3 next to a Dunlop GCB95 Cry Baby on the same guitar and amp reveals the architectural differences immediately. The Cry Baby has a more pronounced, aggressive mid-frequency peak — a sharper “vowel” on each syllable. The WH10V3’s sweep is wider and less peaked, producing a sound that players often describe as “liquid,” “smooth,” or “filter-like.” At the bottom of the sweep the WH10V3 moves into lower territory than the Cry Baby, which is partly why Frusciante’s wah lines have more bass content than a comparable Cry Baby player.

The bass mode on guitar deserves specific attention. Switching the WH10V3 to bass mode (175Hz–1.1kHz) while playing guitar doesn’t just make the wah sound bass-appropriate — it moves the entire sweep into envelope filter territory, where the effect responds to dynamics differently and the bottom end of the sweep is noticeably fuller. Some players use this mode exclusively even for conventional guitar parts, particularly in funk contexts where the envelope-filter quality blends more naturally with clean single-coil tones than the aggressive peak of a standard Cry Baby in mid-frequency territory.

The depth knob, new to the V3, is a genuine addition rather than just a marketing feature. At lower depth settings the wah effect is subtle — more of a presence filter than a dramatic effect, useful for rhythm work where you want movement without the wah dominating. At higher depth settings the effect is full and dramatic. The useful range covers more than enough sonic territory for both subtle and extreme applications.

Comparisons

WH10V3 vs. Dunlop Cry Baby GCB95

The Dunlop Cry Baby GCB95 is the market-dominant wah pedal and the WH10V3’s most natural comparison point. The GCB95 uses a Fasel inductor to create a sharper, more pronounced mid-frequency peak. Its wah character is more aggressive and vocal — better for players seeking the Hendrix, Slash, or classic rock wah articulation. The WH10V3’s op-amp circuit is wider and smoother, better for players seeking Frusciante’s tones or an envelope-filter-like quality. The GCB95 lacks a bass mode, depth control, or true bypass option. Price-wise the GCB95 is cheaper at approximately $80–90 new. If you’re chasing classic rock wah sounds the GCB95 is correct. If you’re chasing RHCP or want the wider op-amp character, the WH10V3 is the choice.

WH10V3 vs. Dunlop Cry Baby 535Q

The Dunlop 535Q adds variable Q (resonance) and a frequency range selector to the Cry Baby family, making it significantly more versatile than the GCB95 while remaining inductor-based. At ~$120–140 new it overlaps with the WH10V3’s price point. The 535Q’s adjustable Q lets it produce both sharp, vocal peaks and smoother sweeps, but the fundamental inductor character remains different from the WH10V3’s op-amp topology. Players who want the most versatile Cry Baby should consider the 535Q. Players who specifically want the op-amp character should choose the WH10V3.

WH10V3 vs. Original WH10 V1

Vintage WH10 V1 units in good condition trade at $200–400+ on the used market, significantly more than the V3’s new price. The V3 adds true bypass and a depth control that the V1 lacks. Some audiophiles argue that the V1’s plastic housing has subtle resonance characteristics absent in the die-cast V3, but this is contested. The V3 is unambiguously more practical: better build quality, selectable bypass, depth control, and available new. Unless you specifically need the exact V1 character for historical accuracy (unlikely in most playing contexts), the V3 represents far better value.

WH10V3 vs. WH10V2

The V2 is the direct predecessor, also using the op-amp circuit. The V3 adds the lever-switch selectable bypass (V2 was buffered bypass only), the depth control, and the die-cast housing (V2 had improved housing vs. V1 but not die-cast metal). If you own a functional V2, the upgrade to V3 depends on whether selectable bypass or depth control are meaningful for your setup. If you’re buying new, there’s no reason to seek out a V2 over a V3.

Buying Guide and Ownership Notes

The WH10V3 is currently in production and available new from major retailers at approximately $99–130. The Sweetwater/Guitar Center street price has settled below the $129.99 launch price in most markets. Used examples in excellent condition trade at $65–100. Given the new price, used units at $85+ require careful justification — the new warranty is more valuable at this price tier than for higher-priced boutique pedals.

Power draw is 12mA at 9V — one of the lowest of any wah pedal on the market. Any isolated 100mA supply output handles it without concern. Battery operation is supported and practical for the current draw, but the wah’s physical rocking action means it should not share power with noise-sensitive components through daisy chain. Isolated power is recommended even though the draw is modest, simply because wahs are mechanically active pedals and any shared power introduces noise risk.

The input is on the right side and output on the left, which is standard wah convention but worth noting for pedalboard cable routing. The die-cast metal housing is substantially more road-worthy than the original WH10 V1 and V2 plastic bodies. The footswitch is robust, and the rocker mechanism shows no signs of the material fatigue that sometimes appeared in the original plastic-bodied units.

The bypass lever switch requires deliberate operation — it won’t accidentally toggle during performance. Set it once for your board configuration and leave it. For most players running a modern pedalboard with other buffered bypass pedals (any Boss compact, for example), buffered bypass on the WH10V3 is appropriate and maintains the original V1 circuit behavior. True bypass is more appropriate for players running an all-true-bypass board who want zero signal interference when the wah is disengaged.

One practical note: the WH10V3 runs bass mode most usefully with single-coil pickups on guitar. Humbuckers in bass mode can produce a muddy low-frequency response because the sweep starts at 175Hz — near the fundamentals of guitar’s lower strings with humbuckers’ inherently fuller low end. Single coils let the bass mode sweep cut through clearly.
