I think people hear are trying to help you find something thats fit for purpose and something that you'll get your money's worth using.
I read that UG thread and there where a lot of people suggesting stuff that I would personally avoid, but I know some people hear would use it happily. Im talking specifically about the Line 6 stuff. Every Line 6 amp ive played is nowhere near as good as a nice valve amp.
If it was me... I might look for an old Marshall VS100 head. I think those are under rated, but the dont make them any more. the AVT range replaced them, and I don't like the AVT's.
I also don't like thing like Vox modeling amps, i can't remember which ones in particular.
Right now I have gigging amps that I run real quiet at home. The Uberschall I have doens't sound that good at low volume. Maybe better than a cube, but you need it loud to get the power stage character and to get the speakers driven fully. Its not like is passable either. Im forever trying to EQ it so it sounds better, but really i know it just need to be louder for the EQ and everything to work.
I had the same issue when playing a dual rec at low volume (that was worse) and like I said, I had a 6505 head I gigged with and used at home and it might be better than some budget low wattage SS or hybrids, but its still overkill, and like MDV says, 60watts isn't really much quieter than 120watts.
On the PLUS side, if you did get that amp, then at least if you start a band you won't need to buy a new amp. You can also pop something like an EQ pedal with a level control in the loop, and use that to keep your volume down and add some boost/cut to certain frequencies.
see if you can find HTH's thread on here. He had a modded epiphone had that sounded pretty mean, and im sure he could tweak it for what you want.
