SPAH is set for St. Louis in 1996, according to an announcement during

for a reference, Harv).
I think what we're looking at here (in either the mike or guitar
single C to make sure that the signal stays bright as the volume

frequencies generated by the crystal simply appear across the
voltage drop, resulting in a lower voltage signal (containing the
desired lower volume -- your basic volume control.

independently corroborated it's supposed to be :), it offers
path (lower reactance, actually) than going through the R1 part
specifically, the reactance it offers each frequency component),
input impedance of the amp (Zin).

increasingly better to higher frequencies, and the higher the
robots in there somewhere? :).
There are actually some pretty complex little current loops one
but the bottom line would appear to be that as the overall volume
conceivably all lip smacks and dog whistles just before it all
with this puppy?)
Of course, what specific effect C has on all this is still
directly determines the reactance (Xc) it offers at any given
but some quick, sloppy number crunching tells me that, say,
it won't affect doodley at 100 Hz. Make it more towards .01mf,
listeners of the non-canine persuasion.
BTW, I don't get the referenced mention to this C somehow
reference to the C affecting the mike's impedance is arguably
major component of the mike's output impedance is R2 (another
the amp input Zin, presumably pretty high, starts looking at an

jack on one's amp to plug this baby into, HI or LO (impedance)?
Input 2 is 136K (borne out by the R values in its clever little
this 500K mike volume pot close to wide open most of the time, HI
(and running the volume up with the amp further down the line),




P.S. After all this tech talk, I feel kind of obligated to

careful inventory of what I'm using (and I ain't a Tone King, especially
area). I always tell 'em that the quest for tone starts with a whole lot
that the more I practice and the better I get, the less the equipment


but first learn to make 'em laugh and cry through a shitty house
much falls into proper perspective. B*

My guitarist friend thought that those were both in D (the band), with


my minimalist Desert Island Survival Pak, I can add that "Ah'w Baby" is in G,
