Wilson Effects Modified WH10V3

The Wilson Effects Modified WH10V3 is an Ibanez WH10V3 wah taken by Wilson Effects and rebuilt to the specifications of the original WH10V1. The stock potentiometer is replaced with a V1 replica potentiometer, the darker tone of the V3 is corrected with capacitor modifications, the oversized toggle switch is replaced with a dedicated volume control, and the pedal is converted to true bypass¹.

Wilson Effects describes the stock WH10V3 as an update that "missed the mark in capturing the original's bright, punchy sweep," and says that with these mods the pedal "finally sounds and feels like the original while adding modern flexibility"¹. The modded units are only available in select shops and in limited quantities¹.

An Ibanez WH10V3 modified to V1 specs

The Ibanez WH10 is a wah pedal with a long history. Ibanez reissued it as the WH10V2³. TONEHOME notes that the 2009 reissue called the WH10v2 is actually version 3, which is where the naming gets confusing for players comparing units⁴.

Wilson Effects' view of the family is blunt: stock WH10V3 and V2 pedals have a darker, less pronounced sweep compared to the original WH-10 V1, and the V3's op-amp-based buffer (where the V2 carries the original buffer design) colors the tone⁵. The Modified WH10V3 addresses this in two ways:

• Capacitor modifications correct the darker tone of the V3, which Wilson Effects says restores "the crisp sparkle and punchy funk of the original WH-10"¹.
• A V1 replica potentiometer replaces the stock pot, an accurate reproduction of the WH10V1 potentiometer created by reverse engineering an actual V1 pot¹.

Wilson Effects lists the Modified WH10V3 as played by John Frusciante of the Red Hot Chili Peppers⁶.

The volume control and true bypass

Two of the most practical changes concern the controls and the switching.

The stock WH10V3 uses an oversized toggle switch. Wilson Effects has replaced it with a dedicated volume control, so a player can dial in the exact amount of boost the wah provides, or remove it entirely¹. On the related WH10V3 Retrofit, the same idea appears as pre and post effect volume control: the pre-effect volume is a trimmer located inside on the circuit board, while the post-effect control sits outside⁷.

The switching is converted to true bypass, which Wilson Effects says makes for a cleaner signal path when the wah is disengaged¹. The stock V3 actually ships with a selectable true/buffered bypass switch, an improvement over the V2, but the mod makes true bypass the permanent configuration⁸.

Retrofit and pot swap versions

Wilson Effects sells several related products around the same platform, and the differences matter when comparing prices and availability.

The retrofit route is worth understanding. The WH10V3 Retrofit is built around the original Ten Spot II circuit and includes true bypass switching that eliminates tone loss when the wah is off, a 6-position guitar DIP switch Q-control for fine-tuning the wah's response, and 2x 6-position bass DIP switch Q-controls to custom-tailor the bass wah settings¹⁰. The Q control for guitar and bass settings works via internal DIP switches⁷.

For players who only need the pot, the Wilson Effects WH10 Replacement Pot is compatible with the WH10V1, V2, V3, Funk Factory, and Ten Spot II¹².

Where it sits among wah pedals

For a player weighing options, the Modified WH10V3 is one entry in a wider Wilson Effects lineup built around the WH-10 circuit, alongside the Ten Spot II V.3 and the Funk Factory. The choice mostly comes down to whether you already own a WH10V3: if you do, the retrofit service at $165.00 brings the same circuit ideas to your own pedal¹⁰; if you do not, the modified or assembled versions are complete pedals¹¹¹. More generally, it belongs to the wah family of filter pedals.
