Re: what's your best amp for your bedroom ?
I think a 1 watt tube amp (or more likely, a higher wattage tube amp with a 1 watt setting) is the way to go.
1 watt of tube amp in a bedroom can still be really loud, like neighbors-call-the-cops loud. But I prefer the feel over the various solid state/digital practice setups I have had.
I've had 3 tube amps at 1 watt:
1. Marshall DSL1C - Superb feature set (2 channels footswitchable, effects loop, very nice and warm clean channel). Drive channel was a little thin for me, though, even with Deep switch engaged.
2. Peavey 6505 MH, 1 watt setting - Rhythm channel is awesome, I just live there. It goes all the way up to classic metal. Warm and alive and responsive, even at 1 watt. I don't really have a need for the Lead channel; too much gain for me.
3. Hughes & Kettner Tubemeister 18 Twelve, 1 watt setting - Excellent amp, very different from the Peavey. Tone and feel is much more hi-fi, though not sterile. The tone is very vivid and intense, especially when EMGs are driving the amp. Clean channel is a bit bright for my taste, but it could do a decent Vox thing if you're into that. This 1 watt is very loud - I am usually around 7 o'clock volume-wise. In contrast, on the Peavey 6505 MH 1 watt setting, I can get up to 11 or 12 o'clock (depending on gain setting) to get similar volume.
I also spent a good amount of time with the Randall RD1H in a store and *loved* it. I got everything from dirty, edge-of-breakup tones all the way to full-on metal with just a few knob twists. I am seriously considering getting this for a practice rig b/c I prefer fewer knobs and controls.
