Death 55, Im not saying a half stack or full stack is bad, I have two 4x12 cabinets and the high power amps myself, but in a small venue playing situation, I can't get the tone Im wanting because I cant turn up the amps high enough to get the tubes cookin without blowing eardrums and causing stuff to fall off the walls. If I play outdoors, hell yeah break out the big guns. I have had no luck using attenuators, or keeping the master volume knob turned down, its just not the same. for the record I read where jethrol tull recorded three albums in the studio with the studio 15 and most recording is done with lower wattage amps in the studio's. If you have a place to practice big enough to turn a 100 watt amp on 8 or 9 your very fortunate, and should crank the hell out of it.I dont play out anymore, I get together with the guys in a large basement and jam, and I will assure you the drummer can't drown me out.Have a good one and [ROCK ON] Guitarmanxxxx
