Could be, could be. And more gain, as you said. Had the gain higher in this video, but when I shot the one in the OP, the static was really getting to me.
Amp is really noisy at higher gain levels, plus I stand within three or four feet of it at relatively loud volumes. I have a Decimator G string inbound that should allow me to tame it. Will be useful for other amps too.
I don't really have a lot of amps, so I tend to basically play through the same ones over and over unless I get something new. Focus on writing mostly, but I do record to just bounce the idea of people and also work on my skills in my dinky studio. Really a suboptimal space.
Probably go into the Mark IV again in the near future, will try some of that, gracie.
