What is the difference in these push/pull pots?

[LogicallyInsane]

Ok,
I have triple shots installed, and am wanting to add the out of phase stuff that you can do with push/pull pots..

Basically, I've gotten to this point, and I don't know what the difference in the pots are, and which I need for just a basic push/pull out of phase ordeal..

One says Dual mini pot and the other doesn't...

Which would be the best? What does "dual" even mean in this particular setting?

Thanks ahead of times..

no idea, it seems dual has a ... "dual" meaning for them, since in other pots the term dual is used to describe actually two concentric pots, why don't you go for a standard PP pot? also pay attention to "Audio" vs "Linear" tap.
Basically most pots will fail sooner or later, just handle it with care, do not over solder on it and it might last longer.
from the two you posted i would go for the non-dual one. if you diff the two texts the only word that differs is the word "dual"

Basically wanting to order from the same company, and was trying to stay with the same brand so they're all the same when it comes to twisting.. different brands are either harder to turn or easier.. I kinda want em all the same..
Heard bourns was a good brand, so was tryin to stick to them.. this company does sell alpha push/pulls too.. so I may wind up goin with those...

And yeah. I've got linear 500ks for the tones, and was goin with these audio push/pulls for the volume..

Maybe the difference is the knurling of the knurled shaft. I once bought a Bourns regular guitar pot with a 1/4" shaft, but the 18-spline knurling wouldn't fit regular Gibson/Fender U.S. spec knobs. I think maybe the one with "21" in the number might refer to a finer 21-spline knurl, that would fit regular US spec knobs. Just guessing here, as they don't say that in the description. To be safe, I would call AES support and ask them. That's my best guess anyway.
