500 Series Pedal Interface and Spring Reverb Driver

Introducing the Garbage Ideas Pedal or Spring (P.o.S.) Drive. In "Pedal" mode the P.o.S. is a 500 series instrument level effect loop through device that we've all become accustomed to. However, in "Spring" mode the P.o.S. engages a secondary amplifier allowing it to drive ANY spring reverb tank with minimal noise or degradation.
