Funny story. About a year ago I was in the local guitar emporium. There were several pedals that I wanted to test drive. One of the salesmen joined me and hooked up the first pedal. I didn’t pay attention to the amp that he plugged into, but it appeared to be a DRRI. The pedal sounded horrible. Digital, grainy and nasty. OK, on to the next one. Same thing!?!
We both looked at each other. He looked confused and horrified. Then he got the ah ha look, unplugged from the first amp and plugged into the DRRI next to it. Problem solved. I then took a closer look at the first amp. Yep, it was a TMDR. Can’t say that it sold me on Tone Master amps, but, as they say, YMMV.
The Tone Masters get rave reviews for how well they work with pedals. Not sure what was going on there but for you but this is one of their strengths. I’ve owned both the Twin and Deluxe versions and they both sound incredible with my pedals, all of them. A key with the Deluxe is having the bright cap clip firmware installed.
