I'm trying to make a high pass filter to replace the neck pick up tone control. kinda like a reverse tone. It is suposed to affect both pick ups. the cap on the filter is a .0001uf. when I play it just sounds like horrible cheap ****. Please help!

So if I swap the two wires on the filter pot it should work?

most likely not, .001uf is ur best bet. they cost like $0.10, its no big deal...

Yeah but it's a $20 drive to the nearest town that sells them lol.

I tried the cap, and it sounds warbly. Quite wierd

great. figure out what you did and patent it.

Looking at the diagram of your High-pass filter it looks a little strange to me Jim. If i'm analyzing it right, its basically just a resistor and a capacitor in parallel which isn't really a "high pass filter" necessarily. It attenuates frequency as you change the resistance value but its not what is taught as being a high pass filter.

If you took the signal from the switch to one end of the capacitor, and then the other end to the middle lug of the potentiometer. Take output from that middle lug of the potentiometer and ground one lug so that you have a variable resistor.

It's not a textbook high-pass filter, but it gets the job done. SYK is the one who helped me figure it out a long-ass time ago. I thought I had stumbled onto something new when I thought of it, but of course it, like everything else, has already been done.

Could you draw a diagram? I'm a bit confused

that one didn't work either, all it does is make the highs sound really bad through distortion

Post pictures of your wiring. I don't think your notice much difference with Jim's circuit due to the fact that output voltage is going to be the same as the input voltage no matter setting on the potentiometer. Thats in parallel with your output jack so the voltage at the output jack is going to be equal to the voltage into the circuit.

Your capacitor may be too small for my idea to work, or i may have drawn the circuit incorrectly.

I have no camera but I'll draw it on paint properly what I just tried

I think it's like this. No camera exept phone cameras. Cap says 332; 332=3300pf

It was your wiring. Like I said, I did that exact thing to my guitar and it works just fine. What you see in the wiring thread is exactly how my bass-cut is wired.

I tried it that way too. Man this has been a mission. I just showed how I tried XgamerGt04's diagram. Maybe i'll just use an inductor. Time to crank out my physics

Your filter circuit will work Jim, but with where his is located its not going to make any difference. With where his is, the output voltage will be the same at all frequencies, which destroys the "filters" aspects of it.
