The Supa-Trem in a smaller box, with the analog signal path kept and a digital oscillator driving it. Opto-1 photocell and an Analog Devices JFET preamp, so what the guitar passes through is still the original circuit.
Volume, Mix and Rate, with a lever for square, sine and warble waveforms. Bypass and tap tempo are the two footswitches, and holding tap for three quarters of a second halves or doubles the rate. It goes slow enough that a full cycle takes around ten seconds and fast past 220 bpm.
Up to 15 dB of boost on tap, and with Mix all the way down it works as a clean analog boost on its own.
