Record-, playback- and erase heads, for true analog tape echoes2 playback heads: One is tap-tempo controllable, one is independently bypass-able. Both will be off when the pedal is bypassedHead2 í?s delay time is dependant on the tape speed (delay time) and its effect on the sound varies with the delay timeEasy tape cassette replacement (unscrew, pull the lever, take out casette, replace).Saturation: Drives the record head into saturation (led peak indication)Feedback: Adjusts the amount of feedback on both delays. This control can make the unit self-oscillate. Controllable externally by expression pedal inputDelay time: Varies from appr. 8 ms. to 3 sec (preliminary specs). The tempo can be tapped (does not apply to head2)Master boost (situated right before the output) goes from unity gain to +20dB boost for overall volume boostsChorus: Built-in tape modulation. This varies the tape speed in very small amounts, resulting in pitch modulation of the delaysDelay level: Adjusts the level of the two playback heads24VDC powered, for really high headroom. (In excess of +20dBu)True 85KHz, 60V bias oscillator to ensure pre-magnetization of the tapeC30 1/8" chrome tape for extra long lifeAll analog signal path
