[Harp-L] A little help with wiring a volume pot

[Greg Heumann <greg@xxxxxxxxxxx>]

Hi, Christopher

There is more than one way to wire a volume pot. I have made and sold  
hundreds. If you look on the FAQ page of my website (accesible from  
the page covering vintage (hi-impedance) volume controls, among other  
things you'll find a schematic for a generic control.

The main page is http://www.blowsmeaway.com - the faq is at http://
