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.
