As a point of reference, I've owned four Fuchs amps (including a recent dogears hand tuned ODS50-SLX), a TR Custom Reverb, and have played others. (I currently have a D'Lite build pending.) Not nearly as many D amps as some here, but not insignificant either.
My current favorite gigging amp (and the only Fuchs I strill own) is still an older ODS30 that is a bit of a mutant with a MM OT and some early SLX updates with a couple of years worth of tube selection, trim pot tweaks, speaker/cab selection, and learning how to best dial it in. In contrast, the Overtone was much, much easier to dial in than any of the D style amps I've owned. I still like the ODS30 a bit better, but I do like the Overtone right out of the box better than any of the other Fuchs or TR amps I've owned, and I haven't even done tube swaps or trim adjustments yet.
The workmanship is excellent and the whole package actually astonishing for $800. The layout allows for easy access to everything and would be very easy to repair, tweak, or mod. It's very quiet and there appear to be no quirks over the full range of operation. IMHO it's a very, very good amp at an amazing price for the level of complexity.
That's not to say anyone is right or wrong about what they like.....in many case it's simply a matter of preference and our ears not being "calibrated" the same way. If we are not all in the same room listening to the same thing, then words only convey so much. So Scott, maybe next time I'm driving through "the swamps of Jersey" I'll bring the Overtone by for a test drive.....
