Right now I'm running a Fender Dual Showman Reverb head (set completely clean..master volume opened right up and adjusting volume on the channels) with an Orange 4x12 cab. The cab is loaded with 4 Celestion Vintage 30's. My goal is to have a rig that can go from a very clean/rich/warm sound to an all out distortion with tight low end response (Note: everything other than the clean canvas to work from is attained via pedals). The clean sound is good (lacking a little warmth that my twin reverb used to have) but when I engage my OD/Distortion/Fuzz pedals the sound is a little too vintage and fizzy for me. My dirt pedals sounded great with my Marshall 4x12 loaded with Celestion G12-65's but lacked a touch of bottom end and tightness. I might try those G12-65's in the Orange Cab? Any suggestions? Thanks in advance!
