Empress Effects Tape Delay - Manual (Page 7)

Controls at a Glance
Power: 9V - 18V DC negative
tip 2.1mm jack. 280mA or greater
bypass stompswitch: when the LED is shining, the delay
effect is applied to the signal. when off, the pedal is being
bypassed
output: sets the overall output level(volume) of the pedal
feedback: controls how long the delayed signal takes to
decay. If turned fully clockwise, the signal will swell instead
of decay
modulation: applies modulation to the delayed signal
- the little setting is a slower, more subtle modulation
- the lots position is a faster, slightly deeper modulation
filter: adds a high pass (hp) or a low pass (lp) filter to the
delayed signal
