So after giving it some thought, I figure that sense my gain levels have come down significantly in my playing style, it might be worth mod'ing my '87 Marshall 800 2210.

I talked to a local tech who said disconnecting the diode gain stage is an easy cinch—no damage to amp or resale value because it can be resoldered back into the line real easy. Like $25.

My question though, is there anything else that can be modded to soften, mellow, and ease the aggression on the amp. I like my Marshall when it digs in, but I want a lighter gain in general. Would this be a clean-channel mod? I heard inserting a 100K 1/2W resistor in series negates the tonal sweep effect of the master volume—i.e., this mod will reduce the thin, over-brittle effect when the master volume is too low.

Basically, I want more warmth, smoother breakup, less harsh tones. What are my options?

Use lower-gain preamp tubes like JAN 5751, JJ ecc803,12au7,12at7,12ay7. Buy a few and try them out in different positions

And if you go this route, you will not have to do anything to the actual amp.

That's an option. I'm still gonna disconnect the diode board, no doubt, though.
