Yeah the ‘70’s ODS I tried wasn’t great at low to medium volumes, but I felt I could hear some potential and once I got it loud it very quickly made me think any other amp I’d tried was trash. To anything else I’d call 3D this was 4 or 5D. I could just play a single high open E, let it ring and hear so much going on in that alone. With most amps you play a note and once you hear it come out of the speaker the sound is as good as it’s gonna get, if anything it might get worse as it sustains, but with this Dumble the initial sound you hear isn’t the best part yet. It kept evolving and got more complex as it sustained. Maybe that’s what guys mean with Dumble bloom, not sure. Anyway, I became a believer since that time. I think it is the same flavor to the ‘70’s Mark I I had like you said, but the same flavor in that the Dumble is premium fresh squeezed oj while the mark I I had would at best be some orange flavored medicine or cough syrup. Can’t even give it from concentrate oj lol. The clean I wasn’t that crazy about either and sounded like you said, except somehow when I went back to amps side by side that I know have great cleans like an old Blackface, somehow they didn’t sound so good after. I remember also this middle aged lady (who’s son plays guitar) went up to me and I expected her to yell at me that it was too loud, but actually she just said how incredible it sounded and wanted to know more about it
I’ve not tried a real Trainwreck sadly, but I’m sure I’d be similarly impressed with that too. The Larry Wrecky I tried and my Alessandro’s sound amazing and those are TW inspired. I liked a lot the Komet’s too, but side by side I felt the Wrecky and Alessandro’s were on another level
