The G-Drive is a variation of the popular "Swell Tone Circuit" with a Vacuum Tube for the ultimate compact and easy to use low-gain/push drive pedal. The G-Drive is designed to produce tube driven classic American tones made popular by the now highly collectable mid-'60s combo amps via either Amp and/or Record-outputs. The G-Drive delivers drive with smooth natural compression, rich complex overtones and yet still remains fundamentally transparent. All of this while remaining dead-quiet even with the output level control maxed out! This G-Drive is in a discontinued black paint job, and comes with the power supply. It's in great condition!
