Emulating sort of a spring reverb sound with the Polymoon engine.
Disclaimer:
Most of my patches are made from scratch (some started from factory presets). Most require firmware 1.1 (or higher). Most were programmed with an expression pedal hooked up to the LVX. So, if the preset does nothing or way too much, you may have to connect an expression pedal and experiment with pedal positions :-)
