Volume Pedal Help

[thisyearsnomine]

I recently just bought the standard Ernie Ball Mono Volume Pedal 6166. It's really nice but with my band, we do a lot of loud to clean guitar parts and when I pull back the volume through the pedal, the tone of my guitar becomes sooo warm and loses all of its treble. I've played the pedal through various guitars and amps and I still get the same sound. Does anyone have any clue what the problem is? Do I need a stereo pedal to get the desired sound I want? I do not think it's my pedal, because I've had people look at it, and it checked out with them. Thanks in advance.

There is a sticky thread on volume pedals that may help you.

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.

Thanks for the help. I don't really understand why anyone would make such a thing if they knew this would happen. Any suggestions on other volume pedals I can afford and just plug in with no problems?

if you understand electronics go to seymourduncan.com and look for their treble bleed modification and apply it to the volume pedal.
