An extremely rare and highly sought-after pedal, the Soldano Super Charger G.T.O. was produced for less than 6 years. It features a two-12AX7 vacuum tube circuit powered by a 110V A/C power cable making full use of the tubes. The term "amp-in-a-box" is thrown around a lot these days to describe the sound of various overdrives and effects pedals, but this truly is an amp in a box. If you're looking for anything from a warm and present tone to an aggressive vintage tube overdrive sound, this is the pedal for you. Original Super Chargers command high prices on the used market, but this one, marked serial number 0007, is possibly the earliest example ever listed for resale since they first released! Original box included!
