I also have an MT-2 that I'm deciding what to do (mod or not). I have experience with a few other Boss pedals, a couple I installed the "Keeley" mods, and another was a ? that the guy I bought the pedal from included. On all three, the reduction of noise (hiss) at idle was really noticeable. Also on all three, the tone control was more useable after the mods, (not off or on), and I think I can get more of the sound I was searching for. In the case of the DS-1, and the BD-2, there is also another option for sound adjustment, with an added switch.
Not trying to suggest you need any mods, but I wondered why Boss didn't put a little better components in their boxes, just for the noise reduction alone.
