I ran my first 5150 thru a marshal 1960AX and really liked it, when I started playing a lot of 7 string
I wnet to V30's, the Green backs farted out sometimes but if you're not down tuning or playing a 7 I think they sound really good.
they smoothed out the one I had a bit, sounded great for that "80's" type of metal and early VH tone.
I wish I still had that cab.
