The PlexiSS amp sim rack effect module compares to a modded Carl Martin Plexitone. As an overdrive or distortion, it provides two separate channels of tubey Marshall plexi tone, along with a boost.
Description
The PlexiSS is three footswitched effects in one circuit. There are two independent FET-based circuits providing Marshall Plexi tones that range from cleanish boost to high-gain metal. Each one has its own Gain and Tone control, with a shared Volume control, similar to a 2-channel (Crunch and Gain) master volume Plexi. In addition, there is a face-melting FET Boost at the end. Channel selection and Boost are controlled by footswitches so you can easily stomp on a different tone as you play.
Configurations
- PlexiSS - There is only one base configuration, but several options for tailoring it your needs. Compares to Carl Martin PlexiTone

Options
- Hi Cut Switch - Add a switched treble and noise cut at the end of the circuit
- Hi Cut (no switch) - Add an always-on treble and noise cut at the end of the circuit
- Custom Clipping - Default is crunchy symmetric red LED clipping on both channels. Choose something different for either channel or both.
- Change Footswitch to Toggle Switch - Change either the Channel footswitch or Boost footswitch (or both) to front panel toggle switch(es). You lose the footswitch flexibility as you play, but same some $$$.
- Custom Op Amp - Default TL072 is a quiet, tubey FET-based op amp. Choose pin-compatible replacement for either Channel or for Boost, or some combination.
- Custom Components - Metal film resistors and a selected set of capacitors are selected for low noise and tone.
