Description
Designed in collaboration with the legendary guitarist Steve Vai, the Morley "Bad Horsie" Steve Vai Signature Wah-Wah (1st Generation) pedal brings a distinct and dynamic voice to any guitarist's setup. Renowned for its optical sensor technology, this pedal eliminates the need for a traditional potentiometer, ensuring a smooth and precise wah effect without the wear and tear of moving parts. The "Bad Horsie" is a true bypass wah, meaning it won't color your tone when not in use, preserving the integrity of your sound. With switchless operation, simply step on the pedal to engage the wah and let go to return to bypass mode, making it incredibly intuitive and stage-friendly. This pedal is built to withstand the rigors of live performance, featuring a rugged metal chassis that can take a beating while protecting your gear.
Whether you're chasing the expressive leads that Steve Vai is famous for or looking to add a unique flavor to your sound, the "Bad Horsie" is engineered to deliver. Its custom-voiced tone is both versatile and distinct, providing a wide sweep range that can accommodate any style of playing. Perfect for both studio and live settings, this pedal is a must-have for those seeking a signature sound with unparalleled reliability.

- Designed in collaboration with Steve Vai

Best Wah I have tried
The way this works is genius, no switch to clamp onto it simply starts as soon as you press down on it meaning you dont need to start your wah at the end of its sound envelope but at the begining where it will sound coolest. It also switches off when not pressed so it conserves power/battery. Its sound isnt adjustable like later versions but honestly the contours are very tastefully done. I put this at the begining of my pedal board right after a tuner as it sounds best before the distortion rather than after it.

very goog concetion of the easy to play for those who have more than X pedals and several pedal board
no switch......buffer ....electro-optical..... short coarse .... but can't stay in place without the help of your foot because it returns back completely to ZERO point ... like a old wah to close or open frequencies ... automatically switch from in use status to bypass when foot step out .. built like a tank (don't forget to use 9v 300 mA DC help to get any annoying noise !!!

Linus Hillborg is confirmed to use the Morley "Bad Horsie" Steve Vai Signature Wah-Wah (1st Generation) as evidenced by a photo he shared on his Instagram account on January 3, 2026. The image clearly shows the pedal on his pedalboard. The photo was posted by Linus under the username @linke1000. The photo is from the venue in Copenhagen where Shrimp Sessions IV was recorded, a live video on YouTube. The link to the video is https://youtu.be/czgwlFncLF8?si=kQKdjXPd2tuGYm0s&t=885. You can see him using the pedal at timestamps 14:45 and 39:50, from the same angle as the photo.
This show has several shots of Richard Bishop's pedals (no board). A shot at 49:06 shows, somewhat implausibly, a Morley "Bad Horsie" wah pedal. I thought this would be a volume pedal, but I can not find a Morley volume pedal with red text across the top.
During a performance with his band "Funk Fragment", German guitarist Julian Wolf used the Morley "Bad Horsie" Steve Vai Signature first generation Wah-Wah pedal as part of his pedalboard in 2018.
