My experience is limited but I do own a Plextortion that I really like. I keep it to use as a back-up with an EHX 44 Magnum in case I loose my amp during a show. The pedal sounds really good and can cover tones from slightly broken up to higher gain modded Marshall tones, especially when using the vintage and modern toggle switch. It sounds good when plugged into the return or run through the clean channel on a tube amp. I was able to get some very good tones when I ran it through my Bassman. I do find it to be tight with no a lot of sag, especially on the modern voicing. All that said it's build solid and I have had no issues with it.
