E1
AMT Electronics E1 Engl emulator preamp. This pedal is not only an emulator of the lead channel from the Engl Fireball, 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 means of doing so is noticing that there are two output jacks: one for instrument-level output, and another for line-level output.
- Thermionic Studios has one(1) E1 available for rental.
Controls
- 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 control adjusts the amount of midrange frequencies in the signal. Turning the knob clockwise increases these frequencies.
- Knob 3 - "High": This control allows you to adjust 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 footswitch toggles the pedal between active/engaged ("on") and bypassed ("off").
Jacks
It's not always immediately obvious why multiple jacks are available. We hope this helps provide some clarity. Avoiding mistakes tends to help avoid bad tone...
- Jack 1 - "Input": Instrument input jack. As the only input jack, despite what we just said above, we hope it's obvious that this particular jack is for an instrument.
- Jack 2 - "Cab Sim Out": This output is full line-level from the preamp and also offers speaker cabinet tone shaping. This output jack can be plugged directly into a mixing console, the input of a power amp, or the return jack of an effects loop of a standard guitar/bass amplifier.
- Jack 3 - "Output": This output is an instrument-level out. This output is attenuated from the line-level that the preamp in this pedal outputs so that further pedal or amplifier tone-shaping can take place.
Bypass: True
The E1 is a true bypass pedal.
General Information
Pre-amp
The E1 is not just a "pedal" in the technical sense that it creates distortion. It is also a pre-amp. As a result, it creates a line-level signal that can be output into the power amp section of any instrument amplifier, or, alternatively, can be directed into a general power amp. This differs from many simple distortion pedals that only alter an instument-level signal and that therefore subsequently require an additional amplifier pre-amp section so as to be boosted to line-level that is then appropriate for being fed into a power amp.
- The "Cab Sim Out" is the output jack closest to the top edge of the pedal and is the line-level output.
- The standard instrument-level output is matched by the instrument input on the other side of the pedal.
Pedal Manual
Phase Inversion: Unknown
We have not yet walked the circuit and the schematics available to us so as to determine whether this pedal inverts phase or not.
Schematic
I'm amazed that we found this!
And then there's another one: version 2(?)
Artists
We are currently unaware of any artists actively using the pedal now, or who have in the past.
