So I got a little extra time to fiddle with my 5150 and micing it up. Although this isnt the tone I am going for it definantly sounds better than my JSX did.
Its a bit fizzy which I dont like but I can tell its easier to get good tones with this head.

 ).  I agree about the fizziness, maybe tame the presence if you have it particularly high (IMO that's really the only "suck" knob on the 5150 if its overused) and play around with mic positioning, but it certainly shits on the JSX already!  What mic did you use homie?
