I'm used to the hard edge after playing Juniors for so long. Half the time playing reggae you're palm muting, so I guess I just took it for granted. Or got used to it. But if we're designing, then what the hell, yeah, shave that edge off!
I never played with a lot of gain when I was in punk bands. Then again, we didn't really have much choice where preamp/gain was concerned anyway, because most 60s/early 70s amps didn't generally have that option. That's why everyone lost their shit over Randall Smith's little hot-rodded Princetons (which grew into the Mesa Boogies) in the 70s...it was a new era of volume control while retaining overdriven tone in a small amp.
I really wanted one of those original Boogies (despite the idiotic name and chair-seat-wicker speaker grille), but a 1x12 would have cost twice what I paid for a 50w Marshall 2x12, and the Marshall wasn't exactly cheap. I think I paid $1200 for it in 79, and a Mesa Boogie was closer to $2,000.
For what it's worth, I didn't have an amp with a preamp control until I got that Marshall. I was playing through Ampegs and occasionally a Sunn before that. So maybe it's just a question of old habits and preferences. Those Sunns were fucking loud, eh. Loudest things I ever heard.
