Make sure the sound emmitting from your cab's speakers is the sound you want on your album.
When I mic my amp, it's to replicate exactly what is coming out. Then you have to select the type of placement from proximity to the inner or outer cone. You'll get plenty of tones there too.
#1 good player
#2 good gear that is sounding like you want it to.
#3 a good mic/preamp/placement on the cone.
#4 analog tape
#5 multiple takes if you don't have multiple amps (make sure you check for phase is you use multiple mics) Find the null spot with white noise and flip your phase
#6 Get a bad ass Mesa rig. (haha my personnal choice... it's not the only rig)
#7 Don't think you can fix it in the mix. Get it right during tracking. You'll hurt your head trying to eq the shit out of something that will never work.
All these things have to be taken into consideration when tracking. Loose one of those elements and you're going to be dissatisfied.
Ps: Trim your gain down to where you can strum a C or G chord and here it clearly and cleanly. Unless you're tracking thrashmetal
