Catalinbread SFT Overdrive Pedal Traditional Ink.
We’ve always been smitten by AMPEG®. Early on, the company was a jazz purist, completely overlooking (and possibly looking down on) more popular genres like Country & Western and Rock, which FENDER® and MARSHALL® openly embraced. From a design standpoint, they took more cues from the hi-fi world than from guitarists, as evidenced by their tube complements, gain stages without cathode capacitors, and the implementation of Baxandall tone controls. They weren’t slouches when it came to innovation either—'Flip-top' combos are a great example. Not to mention, there is at least one model of amplifier that had a torsion bar to adjust the tightness of the speaker baffle!
You can power your SFT with any quality power supply designed for use with effects pedals. The output should be a negative tip DC from 9 to 18 volts. If you want more volume, headroom, and percussive attack, try running an 18 volt power supply. A 9 volt power supply will have a slightly softer sound that saturates more easily.
