Title: Need Push/Pull switch for mod
Post by: NannerPuddin on June 01, 2008, 10:35:36 am: 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

Style "d" or "c"

But tell me, where did you find the elusive 1M???

Post by: NannerPuddin on June 05, 2008, 07:59:11 am: 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.....

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