servant,
Where does the 'hidden' end of that 4.7Kohm resistor connect to?

Where does the 'hidden' end of that 4.7Kohm resistor connect to? In series with C2, the yellow cap. I guess I should have put a blob of solder on the drawing.

Yep,
Essentially, there is a two-pole response from this circuit (as in poles and zeros and not "lugs" QED).
If the circuit is analyzed for the 0.018uF cap (what it effectively is in series w/ a 0.1uF) and 4K7 Ohm resistor when set to "0", one can see that it's just like a standard tone control, with the resistor limiting the "zero" resistance of the pot to 4K7, and hence reducing the peaking effect that I mentioned earlier in this thread.
The 0.1uF cap on the wiper does complicate the response somewhat (pSpice need apply for a clear view) in that it forms a variable parallel RC network (the 0.1uF cap and the top half of the pot) in series w/ the series network comprised of the rest of the pot, the 0.022uF cap, and the 4K7 Ohm resistor.
While the "Grease Bucket" circuit may indeed catch all of these "greased electrons" causing such aforementioned (by Fender at least) undesirable "tone stuff", I've found it somewhat effective to just not turn the tone control all the way to "0".
But then, marketing is (and the "Highways" have been quiet(ly ignored) lately).

Chris, Sounds like that was a case of job security for certain Fender engineers, wouldn't you say? ;D Don't turn it down as far, indeed. I can just see it now: "But these things go all the way down to ZERO!" to you! sumgai

Even an old fart (well past breeding years) quoting Oscar Wilde, won't help those "still in the herd".
"The pleasure is fleeting,
The position ridiculous, and
The expense darnnable." (SuBtle fontification afoot!)
But, few males would do much of anything if'n it wasn't directly fun-full.

It's a low-cut filter into a high-cut filter. The resistor keeps it from "bottoming out" as you roll the knob back. Interesting, but hardly revolutionary. It was probably created by Bill Lawrence.

Ok, so I'm looking at that Varitone circuit and thinking it could go in a rack. Perhaps if one was using a Garcia-type effects loop from/to the guitar before the master volume. Would the cable run wash out any usefulness of the external tone box? Just posing a question as I don't have the aforementioned effects loop, but curiosity will have its way.

So, with all the discussion around the "Greasebucket" modified tone control, has anyone found it actually does produce any significantly different sound compared to a standard (treble cut) tone control that's only turned-down part way?? Is it worth the (minor) effort to make the modification??

I couldn't notice anything different from a normal pot which only goes down to 1. J

kurik does get the Grand Prize for ressurecting the dead! Very nearly seven years since the last post, which beats the old record (held by chuck) by more than 22 months. Way to go, kurik! sumgai

I held the yellow jersey for resurrection back in 2007, but 7+ years sure is a doozie...It would be easy to trounce, but not very sporting n'est ce pas?

Sure... but some places (not so much with our comfy, Nutzy home) will get themselves tied-up in knots if you post a new item covering a topic when there's already an extensive (albeit ancient) thread discussing the same topic... Here, I like to think, we don't mind either way... (!)

Since the only thing you'd get for sacking the quarterback (i.e. resurrecting the oldest thread since we started) is a gen-u-wine NoPrize, I guess it'd be fair dinkum....

Is that where the drummer suddenly appears out of thin air, landing right on the stool, all in one piece, and looking like he just came out of a fight with a wildcat in a phonebooth? How often is that expected to happen, because ST lost a lot of drummers due to bizarre cirumstances, ya know.....
