The Edison preamp is an all tube, EF86 powered preamp pedal capable of providing 20-25db of clean gain using a standard 9v power supply. The Edison has long been favored for its warm, signature tone and can be found of hundreds of pedal boards.
Bass players use it as a front end to get a punchy, rounded tone at the beginning of their signal chain. Guitar players use it to overdrive their amps and other drive pedals, or at the end of their signal chain to warm up their pedal or digital modeling rigs. A boost mode switch below the volume control allows for an edgier, louder tone.
All machining, powder coating, assembly, wiring and design are done locally, and each batch is unique and limited in quantity.
