My 1972 Marshall modded into a Cameron Aldrich. The amp is crazy versatile and the low input makes it have a very useable clean tone. It also has a metro effects loop, so you can easily add effects. Just to point out, it all tube (only 3 preamp tubes, no need to add another), no zeners in this amp.
I made this clip showing that it can do both 80’s and modern metal with ease. Just amp, guitar and cabinet. It doesn’t even need a noise gate.
