Members zephyr Posted October 31, 2011 Members Share Posted October 31, 2011 Does anyone have a diagram for how to wire a push/pull tone control that takes itself out of the signal path when pulled up?Thanks Link to comment Share on other sites More sharing options...
Members wagdog Posted October 31, 2011 Members Share Posted October 31, 2011 Wire the middle lug of the switch to ground and connect the tone cap end that normally goes to ground to the top or bottom of the switch. Don't have a picture. Link to comment Share on other sites More sharing options...
Members zephyr Posted October 31, 2011 Author Members Share Posted October 31, 2011 I found this, but I thought one of the regular "pot" lugs had to be bent onto the case for a ground connection?[ATTACH]339829[/ATTACH] Link to comment Share on other sites More sharing options...
Members wagdog Posted October 31, 2011 Members Share Posted October 31, 2011 That shows what I said, it will work. Neither end of a tone pot is grounded. On your vol pot, one end is grounded. fwiw, a tone control in a guitar is a low-pass circuit; lows pass by it (and continue out to your amp) while highs are shunted to ground. The cap controls what frequencies are passed and the pot (wired as a variable resistor) controls how much of the highs are passed to ground. Lift the end of the cap going to ground and you effectively remove the path to ground for the highs. Link to comment Share on other sites More sharing options...
Members zephyr Posted October 31, 2011 Author Members Share Posted October 31, 2011 So the pot then becomes nothing more than another ground connection for the signal? Link to comment Share on other sites More sharing options...
Members wagdog Posted October 31, 2011 Members Share Posted October 31, 2011 Essentially yes, another path to ground, THROUGH the cap, which controls what frequencies are bled to ground. Roll your tone control to 0 and you will hear mostly bass freqs through your amp because your highs are being bled to ground ground through the cap.

Members wagdog Posted October 31, 2011 Members Share Posted October 31, 2011 Incidentally, that's why the whole "high end tone cap" argument is a bunch of garbage - no signal that goes to the amp passes through the cap - only signal that being tossed away passes through it!

Members zephyr Posted October 31, 2011 Author Members Share Posted October 31, 2011 So if the switch is only disconnecting the cap from the equation, and the the lug on the pot is not connected to ground, what does the pot do when pulled out?Nothing? Just a cap-less connection to ground? Link to comment Share on other sites More sharing options...
Members wagdog Posted October 31, 2011 Members Share Posted October 31, 2011 It does nothing because there is no path to ground for the signal to go through - it's the same as disconnecting the tone control. Link to comment Share on other sites More sharing options...

Members zephyr Posted November 1, 2011 Author Members Share Posted November 1, 2011 Am I supposed to wire the "output" from the tone control to the output jack in addition to the output from the volume?I found another diagram with a different setup, but this in-out thing is confusing me. I don't see where the output is supposed to go (don't see an output on the tone control in any diagrams I've looked at so far, just a connection to ground).

Members wagdog Posted November 1, 2011 Members Share Posted November 1, 2011 There is no "out" on a tone pot (technically, I guess there is an out for the highs it pulls off and that out is ground) - it connects to either the 5-way on a strat, or when it's wired as the only tone pot (how I usually do it, regardless of strat/tele) to the "in" to the vol pot. The tone pot has an "in" and it works by siphoning off highs FROM the signal going to the vol pot. Link to comment Share on other sites More sharing options...
Members zephyr Posted November 1, 2011 Author Members Share Posted November 1, 2011 [ATTACH]339833[/ATTACH] Here is another one I found. This one also seems to have a wire going in from the volume pot, but then illustrating a wire out to somewhere. And if the switch is only taking the cap out of the equation, isn't the pot still functioning as a resistor? Wouldn't the entire signal shunt to ground? I wonder if it would be easier to set up the volume as a puch pull and have the switch simply kill the signal to the tone control... If I can find a diagram for it. I'm thinking I'll probably end up taking it in to have it done... Link to comment Share on other sites More sharing options...
Members zephyr Posted November 1, 2011 Author Members Share Posted November 1, 2011 Prepare yourself for a truly bad drawing.Would this work?Wire everything normal, except use a push pull for the volume and connect the tone control via a switch lug. When the switch is down, the tone control is connected, when it's up, the path is broken.Not sure if that makes sense or is feasible. The signal from each pot lug is represented by one of the 3 pairs of switch lugs, I think?[ATTACH]339834[/ATTACH] Link to comment Share on other sites More sharing options...
Members wagdog Posted November 1, 2011 Members Share Posted November 1, 2011 The lead you labeled "switch" - that also needs to connect to the middle of the tone control switch on the same side as the lead going to the tone pot - then it would work.

Members zephyr Posted November 1, 2011 Author Members Share Posted November 1, 2011 Whoops, I messed it up. Ya that wire is from the selector switch. I assume that the signal from the PU selector goes to the left lug on the pot, then goes out in tandem from the upper left lug on the push pull switch when it is down, but is cut when pulled up. I think... Link to comment Share on other sites More sharing options...
