I am doing some mods on a Boss SD-1 pedal, and I want to activate with a push pull switch on the Level pot, which is a 10k mini pot.  I can't find the 10k with a push pull switch.  Does anyone know where I can find them?  I already found a 1m to use for the drive knob, but I need one for the Level.

Thanks,

Doug

Well I realized that the push/pull pots listed on that page are linear taper only and I think I need the audio taper for the level pot.  Ii talked to the tech guy at Mouser and they don't have one like that.

Back to the drawing board I guess.....

Here's a few ways to give a linear pot an audio taper.  It's supposed to be more accurate than manufactured audio pots and a hell of a lot easier than taking a pot apart and scraping at the conductor.

I picked-up a 1MΩ from here
http://www.torresengineering.com/ampsolshafpu.html

The taper turned out to be pittifully flat to approximately 7 on the vol. dial.  Ended up putting stock pit back in.
