Well son of a bitch... The EchoBox isn't playing well at all with one of my distortion pedals. If I turn the EchoBox on with the Plextortion, it turns the tone into a super harsh trebly mess. Unusable. The EchoBox sounds great clean or with my other two distortion pedals, but not the Plextortion.
The bad news is that the Plextortion is my favorite. So much so that I just ordered the newer version, so I can have two on my board for different tones. I'll probably sell the other distortion pedals I have.
So yeah, the EchoBox is unusable with the Plextortion right now. I emailed the SubDecay dude and ProGuitarShop for ideas. If it doesn't work with the Plextortion, I can't really keep it around.
