So I built this 5e3 back in the summer, with an idea of trying to get low volume saturation using a smaller O/T and so on, along with some bass tightening mods as I found hollowbodies and tweed amps don't really mix. What I ended up with was still way middy, with the breakup still flipping loud. I added the EC Tremolux 1/4 power switch with an added twist that drops it to about 10% output by shunting the signal through some large resistors. One tenth power equals about half volume, so half of flipping loud is quite loud. Still not enough so today I added a master volume which cancels some of the phase inverter via a 1 meg pot. This must be about the easiest mod I've done yet. I'd left the secondary output jack empty for just this kind of mod. I can reach the new MV knob through the cutout on the cab, and now I can get Malcom's Marshall sound at TV volumes. Sort of! At that low a level it starts to get a bit thinner, but it's still ggrrrry enough to have some fun with. Two wires and a pot. That easy. Today I also dropped the first coupling caps down even more, cos I hate huge bass and mmmphy mids. After trying 0.04, and 0.022 I settled on 0.01uF and now those annoying lower mids are in the dustbin of history. What I've ended up with may no longer be a true "Tweed Deluxe" but it's good enough for me.
