Master: Sets the overall volume.
Fuzz: Sets the amount of gain, from clean to fuzzed-out bliss.
Delay: Sets the volume of the delayed signal.
D Time: Controls the delay time (numbers shown in milliseconds) between 20 ms and 1.2 seconds. Long delay times can create flutter, noise, and distortion.
FBack: Controls the feedback of the delays, from slapback to wild runaway oscillation.
Left Toggle: Up for clean blend, down to kill the dry signal and hear only the repeats.
Speed: Controls how fast the modulator runs.
Depth: Sets how far the modulator will swing the delay time. At high intervals, the pitch of the repeats will shift several semitones!
Right Toggle: Up for a smoother modulator waveform, down for a sharp, square-shaped wave.
