One persons bad experience with one TH-30 is no reason to stay away from them. I have owned 2 Rockerverb's and the first one I had had an issue with the reverb making a hissing sound, I called the place I bought it from and about 15 minutes later one of the head guys from England had called me at home to get more details about the problem. He was very professional and offered to pay shipping, labor, parts, etc. to have it fixed. I didn't have time so I ended up trading it for the 100 watt version and it was back in the store working perfect about 10 days later. You can't really beat that for customer service.
Anyway, to answer the original question, a boosted TT still won't sound as tight or brootal as the DT but the DT is not designed for cleans. I use a GSP for my cleans at home.
I guess I'm one of the few who doesn't like the Tiny Terror.
I think it sounds super boxy and tiny, IMO.
I agree 100%. It sounds tinny and small. Like it wants to hit me but has the flu and just can't bring itself to get out of bed.
Tone is in the hands of course, but maybe my hands just aren't good enough for this one.
