The J. Rockett Allan Holdsworth OD/Boost is a versatile, dual-channel pedal designed in collaboration with the legendary jazz fusion guitarist to help him achieve his signature smooth, articulate tone regardless of the backline. It combines a mild, transparent overdrive with an incredibly tweakable boost, which can be cascaded for fiery lead tones.

Core Features and Controls

• Overdrive Channel: Features dedicated controls for Volume, Gain, Bass, and Treble. This allows you to sculpt your frequencies instead of just rolling off the high end.
• Boost Channel: Designed for heavy EQ carving. It has a dedicated boost knob alongside two mini toggle switches:
• • Boost Type: Switches between Fat, Clean, or Treble boost settings.
  • Emphasis Switch: Lets you toggle between Low or High frequency emphasis, acting as an extremely powerful tone-shaping tool. 
• Routing: Both sides can be used independently or cascaded (running the boost into the overdrive) for complex, layered gain. 

Tonal Capabilities and MarketThe J. Rockett Allan Holdsworth Signature OD/Boost is heavily praised for its ability to produce rich, robust, and dynamic mid-gain sounds without muddying up your notes. Because it was originally a limited signature run and is now discontinued, these pedals frequently show up on the used market—typically commanding prices ranging between $400 and $1,500 CAD depending on condition.
