I wouldn’t say “old”, I just built that pedalboard to primarily go for tones up to the early 90’s, which is primarily tones like you mentioned, just maybe less mids/more Cantrell. I’d even go as far as saying that level of gain is pretty much all I need and the only reason I’d switch to a high gain head for more modern tones is due to how those are dialed in for tightness more so than how much gain is on tap.
Petty is an unexpected favorite of mine. I want to say there was a big Petty doc that came out around the same time that Eagles doc came out and they both got me going down their respective rabbit holes and I came out realizing I loved so much more of their music than I thought, they had just gotten so worked into the background of life over the years I stopped paying attention. I love that stuff because my guitar brain tends to shut off and I just soak up the songwriting and they’re just so damn musical.
