Rainmaker consists of a stereo 16-tap spectral delay paired with a 64-tap comb resonator, the latter sporting external triggering options that turn it into a (single-voice) Karplus-Strong synthesizer.

MangledVerb first appeared as an algorithm in the rackmount Eventide Eclipse effects units. It then migrated to the H9 guitar pedal, and is now available as a self-contained plug-in supporting all the usual formats.
