Möist is a PT2399 delay where the delay time is controlled by an LFO. Having pushed the delay time of the PT2399 way beyond recommendations it is possible to make some of the moistest sounds I personally have ever heard in a guitar pedal.
With a simple yet powerful control setup it is possible to get an entire smörgåsbord of modulation in only a 125B footprint. Subtle vibrato, ringmodulated delay lines, sample rate destruction, modulated feedback screams, even normal-ish delay! Just to mention a few possibilities.
