I'm looking for a good speaker, or speaker combo, to go with a marshall jcm800 and a Black Arts Toneworks Pharaoh Fuzz. I'm currently running this setup through a 1960a cab with Celestion gt12-75's and a Avatar 2x12 with Celestion Vintage 30's. The v30's are WAY to muddy and the gt12-75's, while they hold up much better, can sometimes sound like the bottom end is too much for them. I'm playing mainly with a Les paul and and SG tuned to D or dropped C. Looking for something that can really handle chuncky lows.
