J Rockett Audio has just released its new APE preamp pedal. This is based on the legendary Echoplex preamp section, not the delay. What you’re getting here is the preamp inside the old EP3 echo/delay unit.


Echoplex Preamp

J Rocket Audio’s APE uses a 22.5 volt circuit to recreate the old Echoplex EP3 preamp design, to help you recreate the tones of the old EP3. The idea is you apply this pedal to your own delay pedal to give you a true EP3 emulation. The controls available are:

  • MIX – This controls the dry/wet signal from your delay signal inserted into the internal loop.
  • REPEATS – Controls the, well, repeats.
  • REC – When your digital delay is inserted into the loop it controls the gain on the delayed notes, and adjusts some of the intensity of the delay.
  • SEND – Here’s where you connect your digital delay, sending the signal out to your delay pedal.
  • RETURN – This is where you connect your pedal’s output, returning the delay and completing the loop.

The pedal was designed to be used with a digital delay. Basically what you’re doing is enhancing your delay tone, introducing the sound of the original Echoplex 22.5 volt preamp. Of course, you could just use it as a preamp and use it as a boost pedal. The price is relatively reasonable for a circuit with this amount of flexibility. It is a very specific effect, though, with a pretty specialist application and so it will not be for everyone.
