AMT Electronics E1 Engl emulator preamp. This pedal is not only an emulator of the distortion stack from the Engl Powerball, it is also a preamp in its own right and must be handled like a preamp so you can avoid using it incorrectly. The most important is noticing that there are two output jacks: one for instrument-level, and another for line-level.
- Knob 1 - "Low": This knob controls the amount of low-, or bass frequencies in the signal. Turning the knob clockwise increases these frequencies.
- Knob 2 - "Mid": This knob controls the amount of midrange frequencies in the signal. Turning the knob clockwise increases these frequencies.
- Knob 3 - "High": This knob controls the amount of high-, or treble frequencies in the signal. Turning the knob clockwise increases these frequencies.
- Knob 4 - "Level": This knob controls the total amount of signal volume coming from the pedal. Clockwise is louder.
- Knob 5 - "Gain": This knob controls the total signal going into the pedal for creating gain and therefore distortion. Clockwise is more distortion.
- Footswitch 1 - "On/Off": This button-switch toggles the pedal on and off.
We tend not to document pedal inputs and outputs as it's fairly obvious how to plug into and out of a pedal or an amp. However, when there is more than one input or output and therefore different ins or different outs for different reasons, we like to explain why. Avoiding mistakes helps avoid bad tone...
- Jack 1 - "Input": Input
- Jack 2 - "Output Amp": This output is an instrument-level out and this output is attenuated from the line-level that the preamp that is this pedal creates so that further pedal or amplifier tone-shaping can take place.
- Jack 3 - "Output Mixer": This output is full line-level from the preamp and also offers speaker cabinet tone shaping. This out can be plugged directly into a mixing console, or the input of a power amp, or the return jack of an effects loop of a standard guitar/bass amplifier.
The E1 is a true bypass pedal.
I'm amazed that we found this!
And then there's another one: version 2(?)
We are currently unaware of any artists actively using the pedal now, or who have in the past.
