It's very flexible. But if clean tones are your thing, I wouldn't recommend it. To me, the DGT is all about that bridge pickup, with some gain. Very Les Paul-ish... like a LP with some of the punch of a tele. For my rock tones, I love it, it performs exactly as advertised. For my cover band, where I DO use a few clean tones here and there, it's fine. Not as good as my strat or tele, but that's a PAF for you. When split, they are pretty good... I would never record the DGT bridge split in lieu of a tele, and I would never record the DGT neck in lieu of a strat. But for "working" live situations, it's fine.
When I want beautiful cleans and semi-cleans, I go to my HSS strat or tele. When I want Grissom-type rock dirt, while I do love my tele (Rio Grande Muy Grande bridge) and strat (JB bridge), nothing does that better than the DGT.
When I bought it, that's what I expected: a very versatile guitar, better at dirts than cleans, and don't forget that NO guitar is best at everything. The DGT and HSS Strat are the guitars I use in my rock cover band, because they are Swiss army knives.
OH: and as to the cleanup by rolling down the guitar's volume: that's VERY amp-dependent; it's way more amp-dependent than guitar-dependent. The DGT cleans up much better (great) on my NMV amps; on my Hot Cat dirty channel, not so much. But that's the AMP, not the guitar... I can say the same thing for my tele and strat (both of which have "treble bleeds").
