Funnily, I've rediscovered the 5150 block with 8.01 (although I like the Brit 800 too, but for different purpose). 5150 can be responsive, I've found a new compressor setting recently and now it's my amp to go for high gain. This Brit model again is spectacular. Like I said, it works best for me with neck pup and although I like high gain, I spend 50% of the time playing with it, the sounds just come out from the soul.
