The sleeve on the plug puts the battery - in the circuit when you plug in the cord , unplug it and the battery is off .<br />

Roosterman, I had a buzz pretty decent, maybe a 2 or 3 (based on how loud the amp would have been), but touching it boosted it to like a 6. It was pretty bad, but fixing the ground issue solved the majority of it. I did notice the lamp above my soldering station contributed some nice hum to the equation, so I sheilded the box (and turned off the lamp!), and now this baby is pretty silent. Now I just gotta string it up...... expect pics, vids, all that good stuff to follow soon! :-)<br />

RL Mott, damn right... radio shack ain't cuttin' it. They don't even offer pots in 250K or 500K values, and their nearest store to me is at least a 30 minute drive. Thank you for that link! I have a feeling I'll be utilizing it soon in the near future...

I've seen this before on a cheap import jack . Continuity tests good to the jack's ground <i>contact</i> ,<br />
but the <i>crimpover</i> is intermittent/bad from the contact to the "sleeve" , which is the only<br />
ground contact to the cord's plug . The only thing cheap about Ratshack parts is the quality .<br />

Hey Nathan, glad you sorted it!<br />
<br />
Iv just had exactly the same problem with a git... no buzz at all when the treble is rolled off, but a bit of a hum when it is rolled on again.<br />
<br />
I systematically swapped the cap, the pots, the jack, the earth, the pup... made no difference at all!<br />
<br />
Out of interest, how loud was your buzz? On a scale of 0 - 10, where 0 is silent, and 10 is like the volume of buzz you get when you forget to plug in, Id say mine was a 2.... everything in the room needed to be…

Well, I believe the problem has been solved.<br />
<br />
As a tip for future folks with this particular issue, try this: If you've got a multimeter, set it to test for continuity. Test to see if your ground circuit is complete by testing the lug on the input jack you wire to ground. If that works, plug a cable into the jack and then test the ground on the sleeve of the guitar cable that's not plugged into the guitar.<br />

The mystery deepens:<br />
<br />
With the tone pot at 0, the buzz is gone. Now, turning the volume from 0 to 10 and vice versa, the buzz is gone at 0 and 10 but present everywhere in between.<br />
<br />
Is it possible the pots are bogus? Another example of "friends should not let friends use bad pot(s)?" :-)
