I have a Mesa Boogie Triaxis, ISP Decimator Pro Rack G, TC Electronics G Major, Mesa Boogie Power 2:90, Marshall 1960 straight 4/12 cab, Dunlop 535Q wah, and a DMC Ground Control pro. I run my rig in stereo through the Mashall 1960 straight 4/12 cab....speakers are stock Celestions. What would using a Mesa 4/12 Cab net me? What about 2 Mesa 2/12's split wide for a nice stereo sound? Tried a Genz Benz 2/12....loved the look, build, design...but it lacked the thud. Oh...I play in a cover band that plays Creed to Maroon 5 to ZZ Top to Chris Isaak. I mainly use humbuckers...but do own one Strat w/ singles. Anyways....thoughts? Any gear I should add to benefit sound wise? I'm a GAS'er so let the buying begin!
