I have several amps.
One is a Fender Pro Junior, got it off ebay for about $200. It has 15W and a 10" speaker, probably too small for you. It has tremendous tone.
Another is a Fender Blues Deluxe, got it off Ebay for $350. 40W, 12" speaker, and loud enough to rip your head off. This is a great amp and has great tone, both clean and overdrive.
Another is an old Kalamazoo Bass 10, around 18W with 2 10" speakers. Loud, but has crappy overdrive sound when you crank it. Got it from a friend for $100. Sounds great for bass and clean guitar, unless you run a Tube Screamer into it. From there it sounds great.
Another is a Mesa Tri-Axis with a 2:Ninety going into a 4x12. Probably about $2k for the whole shebang. Louder than God - and I'm not exaggerating. Seriously loud. I have never, ever, ever had the need to turn it up past 3 or 4. Tone from the heavens. Overkill for anything I've ever done. Too much to lug around, too.
If you have $300 to spend, you can get a good Blues Junior for $250 used and it's a tone machine. Seriously, stay away from Peavey - crappy sound.
