I cannot say enough good things about his work. I had been seriously considering moving on to a more audiophile but less versatile delay like the strymon time line before having these mods done but now I see no need. The signal path is cleaner and more transparent, the noise floor is reduced, it now has variable output gain, the algorithms have less digital grit and of course the switches are hardwired, smooth as silk and accurate. i will have the same thing done to my M-5 eventually. One thing it did not cure was the loop degradation that Jeff Duke described when going in to reverse while in overdub mode at a point other than the beginning or ending of the loop, that i believe is a software issue they never fixed.
