Noise Space Audio Elephant is an exact clone of the preamp section of TS50B. It utilizes +- (bipolar) 15 volt power supply inside the box while powered from your standard 9v center negative dc power supply. The only difference from the original circuit and wildest feature is tonestack bypass. I just love the way it distorts without eq. It's a unique circuit that sounds like nothing else I've ever heard before. You can either use it as your usual distortion pedal right in front of your amp or put it directly to a power amp. Controls: - Three band eq (that can be bypassed) - Gain control- Volume control - Bypass switch on the right - Boost switch on the left - HI/LO input switch (cuts some gain and highs in Lo mode)
