1776 Effects Multiplex Echo Machine. This is a delay pedal that appears to have been wholly designed and implemented by 1776 Effects. What makes this delay different from other delays available in the marketplace is that it enables emulation of three different magnetic tape-style echo/delays from days past:
- The Binson Echorec
- The Roland RE-201 Space Echo
- The Echoplex Ep3
This is done by using two different ICs (integrated circuits) and controlling the timing and order in which each IC has signal fed into it.
Controls
- Knob 1 - "Delay 1": Sets the delay time of the first delay - turning the knob clockwise increases the length of the delay.
- Knob 2 - "Delay 2": Sets the delay time of the second delay - turning the knob clockwise increases the length of the delay.
- Knob 3 - "Feedback": Increases / decreases the number of repeats - turning the knob clockwise increases the number of repeats.
- Knob 4 - "Mix": Adjusts the dry/wet blend. Align the knob directly in the middle to have a 50/50 dry/wet mix.
- Knob 5 (3-position switch) - "Tape Mode": Changes the way the signal is routed through the PT2399’s to simulate tape delays of the past:
- Binson Echo rec
- Roland RE-201 Space Echo
- Echoplex v. Ep3
- Footswitch 1 -"On/Off": This turns the effect on and off in the signal chain
- Footswitch 2 - "Tape Speed": Holding down the momentary footswitch slowly speeds up the delay speed. Releasing the switch slows the speed back down to the time setting of the knob. The tape speed is highly interactive depending on how you have "Delay 2" set.
