Are SM57 capsules available 'loose', or do other capsules exist,
resembling this for close micing [guitar cabs] ?
You are planning to disassemble the microphone and mount the capsule on
your guitar cabinet?
If none comes close, I'd assume an SM57 can be taken apart, i.e.
separating the head. What's the approx dimentions of this assembly?
About 1/4" narrower than the case and less than an inch long.
How much of the SM57's close micing qualities are due to the capsule
itself vs the electronics?
I realize diaphragm material, compliance et al.. matters a great deal.
There are no electronics inside an SM-57. It is a dynamic microphone.
Signal goes directly from the capsule to the cable.
That's not quite true. The signal passes through a 'transformer' in the lower part of the mic before it hits the XLR. It changes the colour of the output signal. If you rewire an SM57 to bypass the transformer it makes quite a bit of difference to the output signal, but in my opinion it makes it sound worse.
I wouldn't recommend disassembling an SM57 though, the internal signal wires in the head will almost certainly break & are just about impossible to fix (unless you're VERY experienced in soldering).
