Coming back to amps, I normally use a Marshall JMP 100 all valve head with a 4x12 cab. If we are gigging without an inhouse PA, which is rare these days, the Marshall cab is a must, for good projection and volume. If there is a PA, the AVT 275 can easily cut it, as you don't need to project with the amp. Also, when miked you rarely hear the warmer all valve sound anyway. Thats how small the difference is. In a studio with a great mike, you would detect a warmer tone with the JMP.
