Ok so I have been messing around with this on the Triple XXX super forty, still don't have it where I want it but using these triple xxx amps with active eq takes a bit of learning. I suspect though it is the fact that I have EL 34 tubes loaded in and I am not apparently a fan of EL 34 tubes. Haven't liked this amps tone since I put them in. I will jack into the XXX head this week and see how it goes. I have not tried the pagan or missionary switch or the trimmer pot yet. I didn't want to do that with the amp I was not partial to. Funny thing is this was a great amp before the tube swap. I have some Marshal friends who love this amp now, funny how we all gravitate to different tones. Sadly I can not make an honest assessment of the pedal till the amp is sorted out. Initially, I think it will be a great pedal.
