I owned an AX cab, just didn't work out for me, so I sold it and now have the EVH 4x12.
I bought the AX second hand 6 months ago from a guy who bought it in 2008. I lived with it for a while, but overall I found it very bright and pokey in the high mids. I took the speakers out, ran 60hz sine-waves thru them for 20 hours each to burn them in more, helped a little but turned out to not be a great combination for that amp even tho the GM25's were UK made.
I went to a local store and lined up 4 quads in a row and the EVH cab smoked them all, it wasn't even close.
I used my EVH 50watt mini, blue channel, front settings at noon, back resonance at 9 o'clock, no effects, Les Paul straight in playing open rocks chords with a few chugs thrown in for good measure.
Other quads were a Kustom with Vintage 30's, (was ok, a bit harsh), a brand new 1960AX (an ice pick fight), big Orange 4x12 with V30's (was ok, but sounded just like a deeper Kustom), and the EVH, great lows and mids, smooth highs and just a great overall tone. I'm a gainiac who likes to play loud-ish so the straight EVH was always going to have an edge with me over the angled cabs.
