Wilson Effects WH10V3 Retrofit – Ultimate WH-10 Mod

Born out of a deep passion for the WH-10 wah circuit, the WH10V3 Retrofit is the ultimate upgrade for your Ibanez WH10V3, bringing it closer than ever to the revered original V1 while offering expanded tonal flexibility.

Originally developed during the WH10V2 era, this project was set aside—until John started playing the modded V3. With a few final refinements, I decided to bring it back with even more options.

​

What Does the Retrofit Offer?

At its core, the WH10V3 Retrofit is built around the original Ten Spot II circuit and includes:

• Fuzz-Friendly Buffer – Ensures your wah plays nicely with fuzz & overdrive pedals

• True Bypass Switching – Eliminates tone loss when the wah is off

• Pre-Effect Volume Control – Reduces unwanted clipping at high depth/volume settings

• Post-Effect Volume Control – Independent output level without affecting wah depth

• 6-Position Guitar DIP Switch Q-Control – Fine-tune the wah’s response for different tones

• 2x 6-Position Bass DIP Switch Q-Controls – Custom-tailor the bass wah settings

• Replica V1 Potentiometer – Matches the exact taper & value of the original WH-10 V1

• Brighter LED – Easily see whether your wah is engaged

​​

A Wah That Works With Your Entire Rig

• Fuzz-Friendly Design – The built-in output buffer ensures perfect impedance matching, letting your wah play seamlessly with fuzz and overdrive pedals.

• Enhanced Tone Customization – The Guitar & Bass DIP switches offer an unprecedented level of control, allowing you to shape the wah’s sweep beyond the stock settings.

• Perfect Volume Control – The pre-effect trimpot reduces clipping, while the post-effect volume knob lets you match your wah’s level to the rest of your rig.

​​

Seamless Installation

The retrofit kit reuses your WH10V3’s existing enclosure and controls as well as:

• 3PDT footswitch

• Guitar/Bass toggle switch is replaced with a volume control

​

This means no major modifications to your pedal’s enclosure—just pure tone enhancement.
