Fuchs amps, with all due respect, sound absolutely nothing like a real Dumble ODS or Dumble modded amp. It doesn't sound like them, it doesn't feel like them, it's not reliable like them... I can tell you this because I've own a Fuchs amp that I've got on a trade(TOS), and tho it sounded just like the other Fuchs amps I've heard through videos, in the room it was not even remotely close to any Dumble I've heard in person, and I've heard quite a few of them, or like any of the ones I own.
Both the Fuchs and most of the Dumble replica, clone or inspired amps I've had the chance to A/B side by side with a real Dumble amp or mod, sounded one dimension, stiff and sterile, with an annoying honky midrange, very blurred low end, icy picking presence and with absolute no bounce at all.
What I've seen, every single time someone brought a Dumble style amp to A/B them with the real deal is that, when they plug into the Dumble, they play for quite a while, before even trying to change the amp settings to their taste. Some don't even touch the settings at all. They just enjoy the amp. However, when plugging most of the replicas right after, every one would spend minutes tweaking the settings, trying to come close to the real deal sound/feel, and after a while trying to adjust the amp, instead of playing it, they give up and ask "Can I plug into the Dumble again?", and there they stay until the get together is over. And it happened every single time someone tried A/Bing them.
Sure, they are not aimed for the metal community at all. That was never his goal. So, they won't chug, they won't sound like Metallica or Meshuggah... but for the purpose they were built for, nothing has ever been better, and most likely, never will.
Dumble knew how to make the perfect amp that would please his clients 110%!
