Title: Serendipity / ZenDrive Voice Pot Question
Post by: Micpoc on December 18, 2016, 05:11:54 PM
As I have consistently since I built my first pedal in 1999, I made a mistake in my Mouser order for a Zendrive build: I neglected to order a 10kB pot for the voice control.  It does not matter how many times I go over the BOM and the shopping cart; a mistake nearly always occurs, and it is always MY fault. :-[ 

I DO have some 5kB pots AND some 25kB pots. Would one of these be appropriate to use in place of the 10kB pot?

5k is actually probably more reasonable for the voice pot than the 10K.

Or use a 25k with a 15/18k in parallel?

Good to know; thanks.

I always forget about parallel resistors... thanks for the reminder.

if you have a 10kA use that and wire it backwards. It will be better than any value of B taper. Otherwise, use the 5k. The 26k won't do anything for almost the entire travel.

No 10kA pot.  :(

Do you not think the parallel resistor will work well with the 25kB?
