It's already been covered - I have two clones and the cleans are indeed superb. I agree, most clone pedals I've bought leave me wanting - They're usually compressed and very heavy on the mids - not like the amps. However, I do like the Dumble tone - love the way they record and cut live - but I've experimented enough with other amps to appreciate it's not the Holy Grail. Lots of great amps out there. In fact for live I don't use my clones anymore - I use a good clean platform and pedals -and for lead tones I vary between an OCD, Tim Pierce drive and Ethos...I know Dumbles are a sacred cow to many. I'll admit that I have owned or played most holy grail amps except for a Dumble. All of the Dumble emulator pedals I have tried I did not like. Maybe the smooth "Wooo" fusion like sustain is not for me. However on the Dumble (and clone) recordings I do like, it's the lush clean tone that gives me wood.
Kimock is a great example of this. Is the clean tone the real HAD magic? Dumble players enlighten me.
I did actually own a Two Rock Kimock signature for a few years - very nice amp but quite different to what I later would have defined as how I heard a Dumble tone.
