If you are looking for smooth and fast operation, firm switching, no noise and no loose signal, DiMarzio pots will please you beyond expectations.
I used two on my guitar, a master vol with phase shifting and a tone one with Parallel/series switch. They couldn't work any better, and I consider myself hard to please. I never like anything.
I've had it worst installing other push/pulls in the past, but these DiMarzio were a walk in the park. Although I admit that bigger soldering points would be more confortable.
I will always recommend these pots.
They have nothing to envy CTS or others.
