Designed for Jerry Garcia's "Tiger" guitar built by Doug Irwin, the unity gain buffer inside was designed by John Cutler and prevents signal loss from cable runs to the pedal board and back to the guitar when using the on board effects loop (OBEL).
While the original preamp was inside the instrument, most guitarists do not want to modifiy the cavity to accommodate the preamp and 9V battery required to power it, so I have made this outboard model available.
Hand built using high quality electrolytic capacitors, 1% metal film resistors, and a Texas Instruments IC. Each pedal is bench tested prior to shipping.
Dimensions: 3.6" x 1.5"
Power: 9V DC (-)
