The Science Fair is a unique overdrive/distortion from Summer School Electronics that allows you to blend 2 classic overdrive flavours into a unique sound. The left side of the pedal, with black knobs, is referred to as the Lab Rat — a hard-clipping crispy distortion. The right side with the green knobs is called the Test Tube — a soft-clipping mid-range overdrive with a mid-hump boost. The 2 sides are run in parallel with individual drive and tone knobs, and the centre silver knob column features a master blend and volume. The Science Fair allows the user to find their signature sound while also being a unique pedal that can provide a variety of options in recording and live applications. Runs on standard 9-volt, neg. center power supply, with a lifetime warranty. Hand built in Syracuse, NY.
