Short DELAYs and loads of FEEDBACK form metallic resonances that only kick in after note decay. Some fretboard techniques (vibrato, etc.) can also coax the tubular sounds out of the gate. These long flutter echoes will eventually decay; thanks to the value of the inline FILTER inside the FEEDBACK loop(s). Bump up the DELAY times for ping-ponging effects.

The expression pedal mapping is there to ‘fade out’ the extreme feedback, with increasingly darker echoes, through nearly inaudible delays. As always, the REPEAT performance switch freezes the delay buffers, while blocking further input. Here, it produces infinite tubing and droning ‘pitches’.
