Okay, I have a few of these finished up and ready to go. I don't particularly enjoy the building aspect of this one, so I most likely won't be building more. I much prefer working on turret boards and terminal strips.
The circuit started as a Civil War BMP but has been worked over quite a bit. It is NOT meant to be a refinement on that particular tone.. instead it has been pushed as far as I was able toward making the heaviest BMP I possibly could. The tone is more open and less saturated than the starting point. It is more gravel-y and is not particularly smooth. Nasty was the goal. The lowend output is huge and the treble is still present, but never thin and biting. The tone control is now useable full sweep. This is basically a BMP that is tuned for maximum lowend and a more open tone that is more rugged and harsh. David Gilmore tones this is not
I used all the regular parts:
Hammond enclosures
Alpha full size pots
Switchcraft jacks
Dakaware phenolic knobs
carbon comps
I've changed the coupling caps, swapped in BC109Cs, worked the clipping sections, and tuned the tone stack, among other things. The ones for sale all have green interiors and light blue Hammertone finishes. All tuning/ testing was done with a pair of SGs tuned to A and B into a Green Classic 120 & an old Orange OD120 through a bunch of Orange cabs. Price is $250 +$15 shipping.
