I've owned a lot of amps in my time and have found some that are pretty cool sounding but have stayed under the radar and can be had used for cheap (under $500 used). I'm always horse trading and exploring different sounds but would like to know what relatively under-appreciated amps have you taken a liking to? For me it would be the following: 1. Mesa Studio Caliber. It's a 22watt two channel amp that is much louder than you'd expect 22 watts to be. It can get a nice Boogie crunch and even get into the scooped metal territory with the contour switch. The cleans are nice but a bit dark and it has surprisingly nice headroom. I've seen them on Craigslist for as little as $450. 2. Ampeg Jet. I loved these amps, at least the older ones. It's a low wattage amp, I think 15 watts. But with a Strat it's magical. It gets more of a low midrangey tone that breaks up a bit when cranked. With an overdrive pedal you can get some nice blues tones with it. It would be good for recording, not so much for gigging. I've given as little as $150 for these. 3. Carvin Belair. Yes, the soak channel CAN be muddy. But this is the best sounding clean amp for the money I've ever found. $250 used for a 50 watt 2x12 tube amp that sounds this good clean? Like I mentioned before, the overdrive can be muddy but I don't push it too hard so it breaks up ok. But I'm going to do some of the Hasserl mods to it and see how it sounds. Even if it just had the clean channel it would be well worth the $250 I paid. 4. Peavey Blues Classic. The 50 watt 1x15 and the 30 watt 1x12 are the two I have experience with. They have a nice full clean tone, especially the 1x15 model. However, the one with the 12 inch speaker sounds much better for distorted tones. If you are a blues player, the 1x15 is bliss with a TS909 in front of it. The biggest drawback is they can be a bit noisy and the reverb sucks. It sounds like it uses solid state to drive the reverb, because it sounds so dull and lifeless next to the dry signal. I've seen them for $350.
