hi,
I own a dumble clone by fuchs. i have no idea what a real dumble sounds like except through listening to albums. the fuchs is damn good! the clean tones are very fat yet clear. the drive is very very fat with the right guitar. it cannot really chug. it doesn't sound like a marshall, but its closer to a marshall type drive than fender or class A type 'buzzy' (to my ears lah) distortion. its not really agressive, just smooth, fat and clear. works good with most pedals too. if a dumble sounds anything like this then i guess they must be good as well. i tried the dumble clone by the local guy who left the prototype at g77, it sounded a whole lot like my amp but with less highs, it was darker, and had less presence somehow, even with the settings identical to my fuchs. the amp was nice but a bit overpriced IMHO. hope this was helpful. :roll:
