PlexiSS

"Two Channels of Marshall Plexi Tone, with a Boost!"

 

 

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 tube-y 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 clean-ish 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

 

Buffers

Has input buffer

 

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)
  • Custom Op Amp - Default TL072 is a quiet, tube-y 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.
