Title: Dual pots with mixed tapers... anybody knows of some?
Post by: Cortexturizer on April 13, 2017, 09:12:42 PM
What I mean is for example a dual pot with one half being a 100K linear and the other a 100K log. Or even better mixed values and tapers both. Are there any out there?

Obviously, one could change the wafers inside but these days I am lazy AF and just wanna give my money to someone.

Thanks! :)

I've seen mixed, dual concentrics for guitars, these are the ones i recall.

Most that I've seen are custom jobs, people mixing and matching as needed. But, I believe some of the VFE pedals use mixed taper duals that were ordered as such from the manufacturer.

So, you can build your own, or save up and buy them in lots of x-thousand from Alpha. Either option is feasible I suppose  ;D

Last time I checked, Peter (VFE) was unloading most of his stock on eBay. Pretty sure there were some mixed taper dual gang pots.

Peter from VFE has been selling lots of 200 pots for a very cheap price.
You can pick from a list of various values and tapers. The dual gang pots had some mixed values you could choose from.

Guys can somebody send me a link to the ebay listing please? Did a search just now and found nothing...

Thank you!

Otherwise I'll just mix and match for what I need...

the pedal I need this for is a volume/wah that uses a double pot, which is around 90-100K log for the volume side and 120-130K for the wah side which is linear.

He doesn't have any pot auctions up at the moment, but here is a link to a previous sale: http://www.ebay.ph/itm/100-QTY-Vimex-16mm-right-angle-PCB-mount-potentiometer-10-tol-multiple-value-/172406016674

there's a tutorial in one of Aion electronics' build docs to do exactly that. basically you need to dissasemble the dual pot and add the resistor disk of a mono pot to achieve what you're after. shouldn't be too hard to do.
