May I suggest that you make an offer to Paleopete for his good old Fender Super Reverb Amp
Are you crazy?? Absolutely looney tunes??? I'll sell my MOTHER before I'll part with my Super Reverb!
OK I'm all better now...
Amps are pretty much a matter of personal preference, but I'll stay away from solid state, thank you. I've played them, large and small, 6 to 130 watts, tube and solid state, combo, half and full stack. And really my only requirement is TUBES. I don't like a master volume type, but can get by with it. Right now my current rig is the Super Reverb, 45 watt straight tube 4x10 combo, and the Peavey MX with a 1967 Kustom 2x12 cabinet, seriously considering a 4x12 cab so it will move more air, maybe get a little better bass response. It did great until I put it onstage beside the super Reverb, now it sounds thin. I might look into a minor modification too, for a bit more bass.
For your purposes, I'd say stick with something around 30-50 watts, tubes and inexpensive. The Peavey Classic 30 is a great amp, I've heard several onstage and they sound really good. I've also played a few, nice amps.
Definitely check out used amps, I rarely even look at new ones any more. If you haunt pawn shops for a while you'll run across a deal here and there, my MX came from a resale shop in Houston, $65 and $120 to repair it. That's under $200 for a 130 watt amp that's been doing a great job onstage for 15 years. The Kustom cabinet cost me $40, $100 for two reconed 12" Emminence speakers from a reconing shop, somebody never picked them up, so for well under $500 I got a teriffic amp and cab, the amp by itself would cost $500 or more new. A 130 watt tube amp now would run about $1000 or so new. I've put that MX and 2x12 cab in some huge clubs too, outdoor gigs, jam sessions, you name it, it's handled it. I wouldn't be afraid to set it up in the Astrodome.
The Super Reverb was given to me by a relative after her husband passed away, as payment for 3 hours working on her computer and it cost me around $30 to replace all the capacitors and most of the resistors in it to get it working right again. (It would play great for 10-15 minutes then the volume would drop like a power tube had been pulled) One local shop has a couple of silver face Super Reverbs around the same age range, 1973, for $1200 or so...I think I got a good deal...A blackface Super would run closer to $2000...and I've seen vintage Fenders go for well over that. I saw a Traynor 1x12 tube combo in a local pawn shop for just under $300 a few weeks ago. Can't beat that...
Any tube amp should work for metal, just run the right stomp box through it. My MX has its own distortion channel, I never use it, my Ibanez SD 9 Sonic Distortion pedal sounds so much better...I use the Super Reverb cranked to 10 for straight amp raunch n' roll, the MX for really really clean, and usually run it with the distortion pedal when I want distortion, and a Marshall Bluesbreaker overdrive pedal through the Super Reverb if I want really raunchy. Swap the SD 9 for something like the DOD American Metal stomp box and it would work fine for metal. The SD 9 is not quite the pedal for a metal sound. Don't let any one tell you metal requires a certain brand of amp, that's crap too. I can get a good sound out of any tube amp, put the right pedal in front of it and it WILL sound good for metal. That includes a good 1x12 combo. My MX with a 1x12 cab did well enough with the SD 9 a metal band in Houston wanted to hire me...I wonder what they would have thought if I'd actually had a good metal style distortion pedal...I was playing clean leads half the time too, just to see if it would work...They loved it. Same for another metal band in San Antonio, I had the Kustom cab then, same SD 9 pedal.
I don't like built in effects either, or digital multi effects boards, the older analog stomp boxes just seem to sound better, and controlling them onstage is easier. I can dial in the basic sound I want before I ever plug in, then tweak the volume level during the first song or two and I don't have to touch anything the rest of the night except the footswitch. About the only built in effect I've ever liked is the chorus built into a lot of amps like the Peavey Chorus 400. If that was a tube amp I'd be looking for one...
Don't pay any attention to anyone who says you "have to have" a half stack to play onstage, if that's true why was Martin Barre of Jethro Tull playing a 2x12 combo (Twin Reverb I think) when I saw them in Houston years ago? Why is Van Wilks now using a Peavey Classic 50? Why was almost every amp in the Eric Clapton Crossroads show a 2x12 tube combo, even ZZ Top? Why were both Stephen Stills and Neil Young using 2x12 combos when I saw them? (Neil Young had a Peavey Classic 50 I'm pretty sure) I can keep dropping names all day...
That's a load of crap. I've played through 1x12 combos a lot more than my current rig or half stacks, and on the other end I've played through a couple of Marshalls and a Peavey Butcher full stack, 120 watt BEAST of an amp, I loved it. My little 1x12 solid state amp at the time did pretty well too, but the Butcher got me hooked on tube amps and I've never owned a solid state again except for a RMS practice amp a friend gave me because it didn't work. I fixed it, and use it occasionally but normally I play my Fender Champ for a practice amp and run my pedal board through it if I want effects. Usually just guitar and amp though.
Take your time, check pawn shops and newspaper want ads, but I would avoid buying an amp online you can't hear first. You want the amp that sounds good to YOU...I always look in back, if I don't see tubes I move on...if I see tubes, then I listen to it.
