RESOTRON - TRACKING FILTER

Pigtronix Resotron is a multi-mode filter that brings the analog sounds of 70's era synthesizers to the world of envelope pedals for guitar, bass and beyond. Resotron is the first envelope pedal that can be made to follow the pitch of the notes you play. This pitch-following ability causes the filter to move around based on what notes you choose to play, just like an old-school analog keyboard synthesizer. UP and DOWN envelope modes are also included to perform the more traditional, velocity-sensitive filter movement that responds to how hard you hit the strings.
