Curious to know what you guys are using for that old school classic rock tone. I mostly use Friedman blocks but I'd like to get that old school Angus Young tone and so far having a hard time with the Marshall amps. I find most of the Marshalls either too high gain, or too muddy/dark. Yes, I still need to spend more time learning how to tweak the amps for my tastes but thought I'd just ask and see what people are loving. Cheers.
