A 1w amp through a 12" speaker is way loud enough for the home - especially if you are using any OD pedals. Personally I can't see why there aren't more on the market.
Me neither. I'd really like to see more of these. I remember really wanting to get a Zvex Nano Head a few years back but didn't due to thinking it was a bit gimmicky. I'd still like one but a more traditional looking head is better to look at IMO.
To be fair, there have been a lot of tiny amps - or "small" amps with power scaling or lower-power settings - hitting the market in the last couple of years. Loads of stuff in the 5-15w range, which maybe isn't quite "bedroom" levels, but it's a positive trend (IMO).
A couple of years ago I was GASing for a Suhr Badger or Fargen Miniplex, maybe a little Cornell or MJW, then we had the Tiny Terror.... now there are all sorts of mainstream offerings from Vox, Blackstar, Hughes & Kettner, Orange has a whole mini-range, even Mesa and Marshall are on board.
True, there are still very few dedicated 1w (or 0.5w!) models, but we're getting there. I almost feel spoilt for choice! :D
