Controls

  • Knob 1 - "Delay 1": Sets the delay time of the first delay
  • Knob 2 - "Delay 2": Sets the delay time of the second delay
  • Knob 3 - "Feedback": Increases / decreases the number of repeats
  • Knob 4 - "Mix": Adjusts the dry/wet blend
  • 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:
    1. Binson Echo rec
    2. Roland RE-201 Space Echo
    3. 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.
