    Well, I've been working on this project for a while, and I'm rather pleased with it. PR circuit with and extra mids knob on the back to get me closer to brownface territory. Ten inch Jupiter SC, adjustable fixed bias, rectifier diodes, bias test points, turret board, DR p/t, hum balance on the heaters- all the stuff I'd want on an amp if I bought one. The mids knob is great- I only went with a 25k with the 6.8k as a backstop to take it back to stock; it adds quite a volume boost. With the bass rolled right back and the mids right up it fixes the "too much bass" that fenders seem to suffer from. Just a little hum in the reverb to debug now.

    And the trem! I tried to get it to act more like a Brownface, with mods to slow it down and increase the wiggle. Very nice it is too.

    PS- cab made by Rory Coupland at a very sensible price. He makes them for the top bootteek builders in the UK.
