Exoplex Vintage Preamp

​The Maestro EP-3 Echoplex tape echo unit was put into production in the early 1970's and found a spot in history as both an echo unit and as an amazing preamp. The EXOPLEX Vintage Preamp draws from the original tone/circuit of the EP-3 when used as a preamp and puts it in a small case that will easily fit on your pedal board.  I’ve included a toggle switch that will switch you between the early version of the unit (which was brighter/crisp) and the later version (which was darker/fatter). There is also a hybrid setting that allows you to split the difference for the best of both worlds. There is an internal charge pump that supplies the circuit with the actual voltage of the original Echoplex (21-22V) for total authenticity. While the pedal is capable of a slight volume boost in certain settings, it is intended to be an always on preamp used last in your chain for its slight phase shift and fattening tone enhancement. Bring a new level of complexity to your amp!
