From all I've read/heard from past threads, I think I'm going to try the DiMarzio DP 123 pups for my Fender Hwy 1 Jazz and the series/parallel switching. I think I would like stacked vol/vol, DPDT switch, tone knob setup. Would this setup offer the most versatility for tone? Any others to consider? Do I need any special pots? My stock pups are very noisey and the tone knob is useless -- always has to be on all the way. For some songs, I turn off my neck pup and fingerpick near the bridge. This is the most tonal diversity I have. I'm new to all of this and will probably have a luthier do the install, but I at least want to know what I'm talking about before I get the job done. Thoughts?
