Description
Overview
The Steve Vai Bad Horsie Wah is a professional-grade expression pedal engineered to the precise specifications of guitar virtuoso Steve Vai. Designed for speed and seamless integration, this pedal utilizes Morley’s renowned Electro-Optical circuitry to eliminate the mechanical noise and wear associated with traditional potentiometers. Its standout feature is the switchless operation, allowing players to engage and disengage the effect instantly without the need for a traditional footswitch.
Key Details
- Switchless Design: Simply step on the pedal to engage Wah mode and step off to return to bypass, enabling rapid transitions during complex performances.
- Steve Vai Signature Tuning: The Wah frequency sweep and response are meticulously calibrated to match Steve Vai’s specific tonal requirements.
- TrueTone Bypass: Integrated buffer circuitry prevents signal loading and maintains pure guitar tone and signal integrity across long cable runs, whether in bypass or Wah mode.
- Electro-Optical Circuitry: Provides a reliable, low-maintenance interface that avoids the “scratchy” noise common in mechanical wah pedals.
- Rugged Construction: Housed in cold-rolled steel for maximum durability on stage, featuring a quick-clip battery door and LED status indication.
Use Cases
- Lead Guitar Performance: Ideal for shredders and lead players who need to engage wah effects instantly without breaking their rhythmic flow.
- Signal Chain Optimization: Perfect for rigs with long cable runs where the TrueTone buffer is necessary to prevent high-end signal loss.
- Multi-Instrumental Use: While designed for guitar, the circuitry is versatile enough to work effectively with bass guitars and keyboards.

No complex configuration is required; the pedal is pre-set to the signature Steve Vai specifications.

Good instrument that plays well. The finish is nice and it holds tune. Minor adjustment needed out of the box.
