Okay, so on a whim, I bought a showcase 5 string body from Warmoth. It is routed for two p'ups in the shape of EMG45's. I'm not a big EMG fan, so I'm looking at what Bartolini offers... And it turns out, they offer *four* different p'ups in that form factor: 72M55C, M55CBC, XXM55C and the XXM55M Now, the Best Bass Gear web site gives some general info on these p'ups, but I'd like to hear from real users as to their experience. I expect I'll mate these to a Bart 3 band preamp. Oh - and one of these p'ups (XXM55C) is listed as a "Quad Coil" - - why might I want that, as opposed to dual coil? And for those who want more data before commenting - Body is swamp ash, and I will be using this bass (hopefully) as my primary slapping 5 (My Zon 5 will be my go-to jazz/fingerstyle bass). Thanks!
