Losing high end when rolling volume down.

[jzguitar]

Hey everyone!

Just wondering if anyone has problems with their high end going away when rolling the volume knob down. I've modded my Strats with capacitors on the volume pots, but the volume pot on my Axis SS is very hard to get to - it's a little crowded in the body cavity with the piezo electronics and such. Any ideas would be appreciated!

messing with different caps is all i could think of...i i've seen inside a peizo equiped axis but my super sport had enough room when i had to change out the tone pot.

Hopefully we all know the words so let's sing along:
A capacitor in parallel with a resistor is a low pass filter. This means high frequencies are blocked. As you increase resistance, (Turn down the volume) you also lower the frequency range that is allowed to pass through your low pass filter. (The highs disappear) The definition of a capacitor is two conductors separated by a dielectric (insulator). Your guitar cable is a shielded cable. The shielding, an insulating material, then the signal line in the middle. This is the best configuration because it is theoretically loss-less as far as power is concerned. Unfortunately, guitar cables have capacitance. Try a good cable like Ernie Ball Low cap cables or George L's. I was amazed at what a difference it made.

Wait, wait, wait.

I thought a resistor was a woman who wouldn't let you...ya know.

There is, of course, the BUFFER. That would convert the signal to low impendence.

you can use a 560pF cap in parallel with a 300k ohm resister across the the two hot leads of the volume pot so save treble as you turn down vol. i read this in some installation guides before and it works pretty well.

I think Torres makes a kit dor this problem. Check the Tone Quest web site.

Thanks!

Thanks for the ideas everyone!
