The 7 Best Wah Pedal

#1

Dunlop GCB95 Cry Baby

Inductor-based wah · Fasel inductor, 30K-500K pot sweep, true hardwire bypass, standard 9V, traditional rocker design$60–$85 used

Best for: Classic wah tone, Hendrix and Clapton sound, affordable starting point

The Dunlop Cry Baby GCB95 is the most iconic wah pedal in production — it's the direct descendant of the original Cry Baby that Jimi Hendrix used on 'Voodoo Child,' Eric Clapton used on 'White Room,' and that appears on thousands of rock, blues, and funk recordings. The Fasel inductor produces the characteristic 'vocal' wah sweep that has defined the effect since 1966. Used at $60–$85, the GCB95 is the starting point for any wah discussion.

What to check used: The GCB95 uses a hardwire bypass switch at the heel position rather than true bypass — when switched off, your signal still passes through the inductor circuit which adds a slight tone coloration compared to true bypass. For most amp and pedal setups this is inaudible, but purists prefer true bypass. The pot can develop scratchy noise over time — contact cleaner solves this in 5 minutes.

#2

Vox V847 Wah

Inductor-based wah · Halo inductor, vintage circuit, wider frequency sweep than Cry Baby, 9V or AC$80–$110 used

Best for: Alternative wah character, slightly different voicing than Cry Baby, UK rock sound

The Vox V847 is the other classic wah pedal — alongside the Cry Baby. Where the Cry Baby has a nasal, vocal character, the Vox V847 has a broader, slightly smoother sweep with more high-frequency content. The Vox wah was used by Jimi Hendrix's contemporaries in the UK rock scene and has appeared on countless British Invasion and classic rock recordings. For players who find the Cry Baby too narrow or nasal, the V847 is the alternative. Used at $80–$110.

What to check used: The V847 wah can accept AC power from a standard 9V AC adapter as well as DC — verify you're using the correct power supply type for your setup. The halo inductor sound is slightly more open than the Fasel in Cry Baby GCBs. Some players find the V847 too bright — verify the sweep character works for your amp and tone.

#3

Dunlop 535Q Cry Baby

Variable-Q wah · Adjustable Q (sweep range) from tight to wide, adjustable frequency range, boost switch, Fasel inductor$110–$155 used

Best for: Players wanting wah customization, funk (tight Q), rock (wide Q), variable sound

The Dunlop 535Q is the Cry Baby with controls — a Q knob adjusts the sweep's resonance peak from tight (narrow, more vocal) to wide (open, more comprehensive frequency sweep). An adjustable boost switch adds up to 18dB of volume for wah-heavy leads. The frequency range adjustment shifts the entire sweep range up or down. For players who have tried standard wahs and found them too narrow or too broad, the 535Q's adjustability solves the problem. Used at $110–$155.

What to check used: The 535Q has multiple controls that require time to dial in correctly. Start with Q at noon, boost off, and frequency range at mid, then adjust from there. The additional controls add useful flexibility but also add a learning curve compared to standard fixed-Q wahs.

#4

Morley Bad Horsie 2

Optical wah (no pot) · Optical switching (no mechanical pot), springless rocker, switchless auto-engage, contour control$80–$120 used

Best for: Players who break pots, Steve Vai's wah sound, switchless auto-engage, smooth rocker

The Morley Bad Horsie 2 is Steve Vai's signature wah — designed with Morley's optical sensor instead of a mechanical potentiometer. This means: no worn-out pot, no scratching noise, and no mechanical failure of the wah sweep. The auto-engage feature detects when your foot is on the pedal and activates the effect without a separate switch. The result is more fluid wah expression with fewer maintenance concerns. Used at $80–$120.

What to check used: The Morley optical system produces a different character than inductor-based wahs — it's generally cleaner and smoother, which some players find less interesting than the Cry Baby's nasal peak. If you specifically want classic Jimi Hendrix wah tone, the Cry Baby GCB95 is closer. The auto-engage threshold is not user-adjustable on the Bad Horsie 2.

#5

Fulltone Clyde Deluxe

Boutique wah with adjustable voicing · Three voicing modes (normal/vintage/swept), Icar inductor, true bypass, adjustable Q$150–$220 used

Best for: Boutique wah variety, vintage Clyde McCoy voicing, true bypass, serious wah player

The Fulltone Clyde Deluxe is one of the most respected boutique wah pedals — it models the original Clyde McCoy wah that Jimi Hendrix used in 1968 (a different circuit from later Cry Babies) with three voicing modes: Normal (current standard voicing), Vintage (1960s Clyde McCoy voicing), and Swept (wider frequency range). The true bypass preserves tone when off. For players who want authentic vintage wah character with modern quality control, the Clyde Deluxe is the reference instrument.

What to check used: Fulltone had controversies in 2020 that affected brand reputation, but the Clyde Deluxe circuit design is highly regarded by players. Verify it's genuine. The Icar inductor is the key component — verify it's original and producing the characteristic Clyde voicing (the vintage mode should have a distinctly different character from modern wahs).

#6

Dunlop Jimi Hendrix JH-1D

Signature wah (Cry Baby series) · Fasel inductor, custom voicing approved by Hendrix estate, hardwire bypass, Foxy Lady decal$90–$130 used

Best for: Hendrix tone specifically, tribute players, collectors

The Dunlop Jimi Hendrix JH-1D is the Cry Baby GCB95 with a custom voice circuit tuned to match the specific wah settings Hendrix preferred — a slightly different Q and frequency peak than the standard GCB95. Approved by the Hendrix estate, it's the definitive choice for players specifically targeting the wah sound on 'Voodoo Child,' 'Machine Gun,' and other Hendrix recordings. Used at $90–$130, it's a modest premium over the standard GCB95 for the Hendrix-specific voicing.

What to check used: For most players who aren't specifically chasing Hendrix tone, the standard GCB95 is identical in build and close in voicing for less money. The Hendrix signature is worth the premium only if the specific vintage Cry Baby voicing is your target. Both use the Fasel inductor and same physical construction.

Xotic XW-1 Wah

Boutique wah with variable inductor · Three inductor options (Fasel, Halo, custom), 3-way voicing switch, true bypass, internal dip switches$180–$260 used

Best for: Players wanting multiple wah characters, studio and session work, boutique build quality

The Xotic XW-1 is the most versatile boutique wah pedal — it comes loaded with three different inductors (Fasel for Cry Baby character, Halo for Vox character, and Xotic custom) that can be switched between via internal DIP switches. A three-way voicing switch changes the overall character within each inductor setting. For studio players or tone experimenters who want to match their wah to specific sounds, the XW-1 covers all the classic wah characters in one pedal. Used at $180–$260.

What to check used: Switching inductors requires opening the pedal and setting internal DIP switches — this is a set-once configuration, not a live performance switching option. Verify all three inductors are present and the DIP switch mechanism is functioning. True bypass operation should produce no signal difference when engaged at unity.

Wah Pedal Buying Checklist

  • Pot noise: Engage the wah and slowly rock the pedal from heel to toe while listening carefully. Any scratching, crackle, or volume jumps indicate a dirty or worn pot. Contact cleaner (CRC QD Electronic Cleaner) can fix minor pot scratching; a worn pot may need replacement ($20-30 part, $30-50 labor). This is the most common wah issue.
  • Inductor integrity: Play through the wah at full engagement and verify the sweep produces a clear frequency peak — the wah should have a distinct 'wah' character with the toe down and a distinct hollow 'wah' character with the heel down. A missing or failed inductor produces a flat, characterless sweep. This is rarer but serious.
  • Bypass switching: Test the bypass: play through the wah bypassed and verify no frequency coloration compared to the signal bypassed at unity gain without the pedal in the signal path. Some wahs (especially vintage) add a very slight treble cut when bypassed — this is the 'tone suck' complaint and indicates a non-true-bypass design. True bypass pedals eliminate this.
  • Rocker mechanism: Rock the pedal from full heel to full toe and verify the mechanism moves smoothly without binding, catching, or requiring unusual force. Check that the pedal returns to heel position without sticking. The rocker spring (if present) should maintain tension throughout the sweep.
  • Power supply: Most wahs use 9V DC center-negative. Vintage wahs designed for AC power (Vox V847) must use the correct power supply type. Verify the correct supply is included or available. Running an AC-designed wah on DC creates a different circuit bias and changes the sound character.

Frequently Asked Questions

How does a wah pedal work?

A wah pedal is a variable bandpass filter — it emphasizes a narrow band of frequencies that shifts up and down in pitch as you rock the pedal rocker with your foot. When you push the pedal forward (toe down), the frequency peak moves up to the treble range, producing a bright, cutting 'wah' sound. When you rock back (heel down), the frequency peak drops to the midrange, producing a hollow, vocal tone. Moving the pedal rhythmically while playing creates the characteristic 'wah-wah' expression effect. The inductor inside the pedal determines the character of the frequency peak.

What is a wah inductor and why does it matter?

The inductor (a coil of wire wrapped around an iron core) is the component that creates the frequency peak in a wah circuit. Different inductors produce different peak characters: Fasel inductors (used in Dunlop Cry Baby) produce a nasal, vocal peak with a relatively narrow Q (frequency bandwidth). Halo inductors (Vox V847) produce a broader peak with more high-frequency content. The inductor is the main reason different wah pedals sound different — more so than the pot, chassis, or other components.

What is the Q setting on a wah pedal?

Q (Quality factor) describes how narrow or broad the frequency peak is in the wah filter. High Q = narrow peak = very nasal, vocal, telephone-like wah sound (classic Cry Baby character). Low Q = wide peak = smoother, broader wah sweep that's less intense. For funk rhythm playing, a higher Q wah is more percussive and cutting. For blues or rock lead work, a lower Q provides more expression range. The Dunlop 535Q lets you adjust this continuously.

Where does the wah pedal go in the signal chain?

Traditional placement: first in the chain, immediately after the guitar (before any other pedals). This produces the most vocal, expressive wah sound. Some players prefer wah after overdrive/distortion for a brighter, more cutting effect (the wah filters the distorted signal). Wah after delay is unusual but creates reverse-sweep effects. The standard position (first in chain) is correct for classic wah tone. Experiment with other positions for creative effects.
