Quick update...the Twin should be in Curtis's hands sometime Tuesday.
Took a bit of time finding a nasty ground loop and solving the lack of tremolo. It's all in tip-top shape now.
I arranged a play test with a colleague in the College of Music who plays a nice '77 SF Twin, and his office is an old recording room for the College, so we were able to crank the Twins and keep out of the line of fire. We started with the SF Twin to get the volume in our heads, then we hooked Curtis's amp to his 2x12 cab.
Curtis's Twin was on 7 and was very full (and loud!). Hearing my friend play his '70s Strat and my Squier Tele through it was just great! Classic sound...a Twin naturally breaking up! FUN!
Now it's up to Curtis to report assuming UPS didn't drop it out of a plane on the way there.
