I’m planning a Bassman build. It will have a 6G6-B for the Bass channel. I’m tempted to go with something unusual for the Normal channel. Maybe a brownface Concert’s tonestack? IDK. I was originally thinking of (and still leaning towards) a two channel amp for clean/dirty (with a PPIMV at the end), but the other brownface amps can grind too. Maybe it’ll be a two channel ROCK amp with a lead and rhythm channel... now I’m not sure what I want out of this amp anymore! — Anyway, what brownface tonestacks would you want to try and what are the differences (if any)?
