I had a lower end Spector that I was gigging for about a year. Was never quite too stoked about the tone but it played nicely. At the beginning of the summer I dug out my old Squier Affinity P (20th Anniversary Ed.) and plugged it in and had a blast. Decided I'd take some time and try fixin her up to play again. Everyone was going crazy over the Classic Vibes and a cheap pickup set from the 60's CV came up in the classifieds so I picked em up, threw em in, and wasn't satisfied with the output or punch and they were very noisy. I had also gone ahead and put an orange drop cap in and shielded the cavity. I know the alnico vs. ceramic, but the fender website doesn't exactly outline what each of these pickups are. So what is the difference between all of these?
