Echo:
The echo effect is designed to emulate the old vintage
tape echo units, with all that they had in low-fidelity noise and
distortion. It has extremely musical and warm echo, so don't
expect any clean sterile digital delay here. To enter the echo
mode press the echo switch and set the echo level on the echo
knob. Turn clock wise for more effect. Turn the repeat knob
clock wise for more repeats. The tone knob works like a filter
with clear crisp echo's in the full clock wise position and warmer
vintage style echo when turned counter clockwise. The echo
time is set on the tempo tap switch and it goes up to 1000
milliseconds. Please note that once disconnected from power,
the echo time will revert to the shortest time.
