A whole lot of the great albums of all time were recorded on small Fender amps pushed into tonal nirvana. The Princeton Reverb is 12-15 watts with a 10" speaker and fairly easily driven into overdrive without making your ears bleed. A deluxe reverb is 22 watts with a 12" speaker and you can get it to overdrive fairly easily as well. The Super Reverb is an awesome 40 watt amp with 4 10" speakers, but unless you have someplace where you can crank it up to at least 6 or 7, you won't be able to get to the sweet spot. The Bassman amps are excellent as well, but they are very loud and you'll need some space to be able to crank them up to breakup. The Twin Reverb is 85 watts and unless you are playing in a stadium, chances are you'll never get to the sweet spot before you go deaf.
The new reissues of these amps are okay, but need better speakers. Your best bet is to look for an old Blackface or an early Silverface which any good amp tech can mod to Blackface specs. The Blackfaces have more defined highs, better cleans and some chime to them. The older Tweeds are darker sounding, have less headroom and a less defined tone, but they are great sounding amps. I like both, but the old tweeds cost more and will probably require new caps, speakers and maybe some other tune up work.
I've had a real Blackface deluxe reverb and it was a very special amp...one I wish I'd never sold. All of these amps take pedals well and are the real amps used to record some of our favorite classic rock...Zep and AC/DC studio albums just to name a few. IMHO, you don't need a dirty channel, you just need a cranked small fender Blackface, early Silverface or Tweed fender and a tube screamer or some other OD pedal of your choice. The Princeton Reverb, at 12-15 watts is VERY loud and provides plenty of volume for home play and small clubs...you can always mike it if you play a larger venue.
One of my favorite combinations is a Princeton Reverb or a Deluxe Reverb running through a 15" cab. The Super Reverb is a very special amp as well, but as I said, it's hard to find a place where you can crank it to the sweet spot. I have a Marshall JTM 30, it's a 30 watt 5881 based amp with a 12" speaker and two channels, and I have a Boogie Blue Angel 1x12 single channel as well. The Marshall doesn't get that much play time. The Boogie has both 6v6 and El84 power tubes and a tube rectifier and can run on either set of power tubes or all of them together. It sounds like a hot rodded Blackface DLX reverb to me when I'm running on the 6v6s or I can get a sort of Voxy tone when I'm using the EL84s...It sounds sort of like a hot rodded Super Reverb when I use all the power tubes.
All of the above are just my opinions and may not be shared by any other living person...however do some research and try some out and you might find that I'm pretty close to being correct. Good luck and we're all counting on you.
