Original owner purchased 2000 studio use only. All original box and paperwork. Excellent condition. Shipping to lower 48, local pickup.

Bypass switch- Turns pedal on and off...when unit is off, signal goes from input to output and won't ruin your sound or affect other pedals in chain. Speed switch- doubles or halves the speed depending on what mode you're in....stays in tempo too!

Hard /Soft switch- goes from regular tremolo to hard on/off "toggle-switch" style stutter no matter where the "Mix" knob is set

Rate knob- controls speed of tremolo Mix knob- pans between straight guitar sound and tremolo

                    effect....towards the left is less effect/more

                    guitar...to the right gets more effect, less guitar.

Tone Tip!!!!! I've been getting calls from guys who are leaving it on the "Hard" setting

with the "Mix" knob almost full-counter-clockwise for a normal trem sound, and when they switch to "Soft"...there is no effect except for a beautiful tone enhancement AND a healthy increase in volume depending on where you set the #1 Trimmer! Try going to bypass and back and notice this phenomenon. Some folks are leaving their Supa-Trems on all night as a tone-booster!

Always disconnect the "in" jack when not in use so that you won't run down the battery, and I recommend using a Carbon-Zinc battery such as the Eveready Classic or Super Heavy-Duty. This pedal has an adapter jack that accepts a Negative Center Pin 9volt DC, use only a 2.1mm shaft diameter connector with it.
