I'm not sure if anyone has tried this Triumph Overdrive pedal, but OMG is it killer! I picked one up at a good price on Reverb. I starting using it to boost my SJ Studio and I think it's the best overdrive I have used. Apparently, one mode is based on the Digitech Bad Monkey and the other on the SD1. I'm really digging the Bad Monkey mode and it just sounds so damn good. They say Wamper makes a hell of a pedal and I'm inclined to agree after trying this one. HIGHLY RECOMMEND!
