Got a new guitar amp the other day. It’s a Mesa Coliseum which was somewhat of a Custom shop order when it was made in the early 80’s. This one appears to be from 1982 which I think would essentially make it a Mark IIB model Mesa but this has 6 6l6 power tubes tubes and can run at an unnecessary 180watts. Probably only a few hundred made. It’s almost got too many options for EQ and dialing in a sound, but when I kept it simple and just cranked the gain and master volume it sounded great. Looking forward to an opportunity to record it. Luckily it has a 1/2 power switch making it only as loud as other really loud amps.
