so after sitting back and reading those posts, I think it may of been a multitude of reasons, but namely, that amp simply sounded better with bass than guitar when fully tuned up. It took me playing through other guitar amps in a band situation and comparing recorded material to see this. And I fully stand by the belief that my playing and tone has changed in the past few years, and my choice in gear has changed along with that.
There is one thing though, its something that I've heard in my amp. It is a low frequency distortion, a crackle of sorts, it only happens when those amps are played very clean, and very loud, no dirt boxes. I hear it in my old amp, and my ex guitarists rig, it was something that was only made apparent to my ears after i had my amp tuned up. Its not speaker distortion on those recordings, its something different. It kinda like how whenever I hear a band playing through mv marshall's all I hear is the high midrange honk, its just a weird low freq distortion that IMO wrecked some of my recorded guitar tone. If i knew then what i know now, I probably would've hooked that puppy up to a scope and searched for that spike, but it is what it is.
