I made the Plexi for CM, and I have worked there for more than 5 years now

Ed works for THD and is a monsterplayer

Ours differes most in the voltage used, and it has two different voices, one for more open older voice, and one more for a fatter saturated voice, plus a clean booster.
It has none of the slight flatness in the sound as some 9v pedals has, meaning that the 3d feel is there, I went for that feel, and that old plus more hotrodded Plexi sound, it is no mega highgainer, but it has plenty of omph in the lows, a clear sound where chords are well defined.
Personally I have plenty of pedals, as a few does not always match up with the different amps I use

So I have a rather large amount of pedals lying around, just waiting to do their thing.
Here is the Plexi with an DR201 Hiwatt top.
