Highway 89 volume pot?

[Alpha579]

Hey all,
Im in the middle of building a highway 89, and ive found my local jaycar dont stock 16mm log 500K pots, the highest they have is 16mm 50K log. Could i use this without much affect, if any, on the sound?
Thanx for all help,
Alex

I think it would somewhat, the 500k long shaft should be readily availible, just about all guitar's with humucking P/u's will have the 500k pot, so most music store's stock this pot as a replacement for Gibson's, Ehpi's, Ibenez,

It will affect the sound. You will have ten times less resistance to ground on your volume pot. You probably won't have that much distortion at the output compared to the 500K pot. At least that is how I understand it...

k, so the 50k pot isnt a great idea, but what about using a linear pot?

[Alpha579]

Just thinking about it, could i just taper the linear 500k pot? by putting a resistor across the wiper and one outer lug? if so, what value would i use?
Thanx,

You could use the 500k linear as is until you get a replacement. Won't hurt anything, the volume will just come up a lot quicker.

what if i put a 250K res between one outer lug and the wiper, would that make it log?

I'm not sure. Read "The secret life of pots" at www.geofex.com
I believe that it will tell you how to do that somewhere in that article.

i think ill just use a linear, it wont make a huge amout of difference...
