Yeah, Chicago blues, a lot of blues rock guys — early ZZ Top is heavy power amp overdrive. The guy who lives in power amp dynamics land is Neil Young. My favorite is Live Rust, listen to Powderfinger followed by Cortez the Killer. The way different notes and phrases have different envelopes, depending on his picking dynamics, almost like it's going through a subtly modulated ADSR/VCA — that's pretty much all overdriven power amp distortion and dynamics.donkey tugger wrote: ↑Fri Aug 16, 2019 9:55 pm Is it a blues rock/widdler/metel thing? I've somehow managed to go 35 years without knowing me preamp from me power amp. Probably doing it wrong.
While every tube amp model would benefit if the power amps were modeled correctly, the differences would be relatively more subtle on modern tube amps compared to vintage models like tweeds, Supros, old Gibsons, Vox, maybe the earliest Marshals, etc. Those models would become radically different beasts, where more modern tube amp models would mostly just have more balls and be more expressive, vastly improved "feel", that kind of stuff.
