This is One Cool Rangemaster.
So this turned out pretty cool. It's kind of like a Rangemaster with a Varitone. The red knob is a four-position rotary switch. It chooses between 4n7, 10n, 22n and 47n input capacitors. The original Rangemasters used 5n, but that's not a common value these days, so most people use 4n7 because it's close enough (for rock 'n roll, yo!). The 10n is much nicer, IMO. Still kind of thin and mean, but with more mean. The 4n7 is a little anemic when you hear it A/B'd with the 10n. The 22n is probably the perfect, "Iommi" cap. It's not quite full-range, but has much more complex mids. Then the 47n is pretty much full-range and a little tubby for my tastes.
Very cool. I was thinking this prototype would give me a good idea where to change the choices of capacitors, but I think these four may be just about perfect. Which is odd, because I usually have to do it wrong 37 times before I get what I'm hoping to get. Heh...
