Actually if you can find one the Ampeg VH 140's were killer ss metal amps. They came in both head and 2x12 versions. They're loud enough to gig with. A good specimen shouldnt cost more than about 400 bones.
I've got a little 15 watt jobber for late-night practice, it's not so bad. At least it's responsive to picking dynamics & doesn't sound like an icepick which is more then I can say for those cheap marshalls or fenders...
Over here in the UK you can get the power block BRAND new for £50 ($100)! I have one as a back up for my valve amps... they are 75 watt per side! Good with pedals.... I actually forgot I had this thing as it stays with the P.A stuff for gigs!!
Re: Which are the best starter/garage band/practice cheap amps?
well I know you said no tube, but I just got a used peavey 5150 off craigslist for 500 flat. 60W heavy metal gain, decent cleans. It also sounds pretty good on low volume (my volume knob rarely goes above 0, never above 1) and will make your drummer sound like a little girl playing pattycake on 3. although pretty much anything peavy is going to be nice and built like a tank.
I have heard great things about randall tone, but apparently they are built out of popcorn and graham crackers. (they break really easy and have no customer support).
I have never been a fan of vox for anything other than clean, same with fender. IMO pedals sound fizzy and lifeleSS even through the fines tube amps.
I tried all the small amps when shopping for a mini amp, including the Roland Cubes... IMO the Vox was way better. It sounded much more "natural" and smoother. The Cube sounded more like an amplified transitor radio to me. I'm not gonna try to sell you on the whole "tube-in-the-preamp" thing, but the Vox does not sound like a SS amp. There is a difference. The amp models and effects on the vox are very good too. Try one against the Cube and decide which one you like best.
BTW - the owners manual for the VOX recommends you CRANK it for the best tone - which I have. It seriously rocks. And my 15 watts with a 8" speaker is enuff to shake the floor and rattle the windows. These amps are loud. I have no doubt 30 or 50 watt plus should be plenty loud for garage practice.
