My background: I have played for over 30 years, but never in a band situation. Because I'm a home-player, my most powerful amp is a 15 watt Vox Pathfinder. Since I originally had no plans to play out and didn't need major volume, I've never paid any attention to large wattage tube amps and have next to zero knowledge/opinions about large watt amps. I just recently joined a band and they like to play LOUD. The other guitarist has a 50 watt Fender of some sort (Blues Deluxe?). I am seeking any advice as to what brands/models to be on the lookout for on the used market and maybe which to avoid. I believe I'd like/need something in the 30 to 50 watt range. I'd like to keep it under $500, but can stretch that upwards for a great deal. Also, currently available in my area are: Blackstar HT 40 Club Mach II $400 Fender Hot Rod Deluxe (PR246) w/ 12" Bugera speaker $450 Fender Twin Amp, new tubes $700 Fender Blues DeVille 2 x 12 $550 Peavey Classic 30 (early 90s) $400 Fender Blues Deluxe (USA), JJ tubes, little beat up looking $490 I am not limiting my search to the above models, they just happen to be available in my area. Thanks in advance for any advice.
