One of my best friends asked me to build him an amp. He got an acoustic several years ago because of me, and he finally got a nice Epiphone Les Paul with a cool black/charcoal flameburst top. So, of course, he needed an amp to play it through. He had an old piece of poplar that he got from his father-in-law years ago and never did anything with it. So, that was the donor board. Cupped! It was a PITA to work with, but that's what I did. It needed a planer, but I don't have one, so I clamped the hell out of it and made it sit down in the joints. I actually worked one corner at a time and doweled it to keep them in place, then hurry and move to the next corner. A combination of black dye, boiled linseed oil, espresso Polyshades, black polyshades, and some clear coats in between got the finish, and I'm sure I could never repeat it if I tried. The wood was pretty oxidized itself, and I couldn't sand enough to get to "white" wood, so I had to roll with it. I've been building this style cabinet off & on the past year, and I really like the clean front of it. I didn't realize that it is basically a Fender White High Fidelity Amp clone until a friend sent me a picture -- I thought I was on to something... The amp has a Hammond 290CAX PT - my last one, and I think they've been discontinued - and a ClassicTone 5w Champ OT. 5uf bypass on V1 since he has a Les Paul; 30-22-10 filter caps; 22k/56k/OFF NFB switch. Jensen C10Q RI speaker. He's an at-home only player, so it's about the least efficient speaker I know of.
