This control was often labeled “reverb” on vintage units, and it controls the amount of echo repeats that are fed back into the can to be reprocessed.Higher settings of the knob create a reverberant and atmospheric character, which many would say is one of the signature elements to the sonic character of an oil can echo.NOTE: Hold the footswitch while turning the Regeneration knob to adjust the tone of the repeats. Noon on the knob is the character that we captured from our reference units, with lower settings being darker, and higher settings brightening the repeats.
