Re: Thinking of upgrading PUPs to Dimarzio Evo's, help?
I second chris101, IMHO Evos are too bright in basswood. I like them in mahogany and alder bodied guitars though. For my money you can't go wrong with set of DiMarzio Tone Zone in the bridge and an Air Norton in the neck.
Keep in mind though, that pickup choices are like ice cream. Baskin-Robbins makes 31 flavors for a reason. So, what I like in a pickup may not be what you like in a pickup.
jim777 makes a great point too, if you purchase them straight from DiMarzio you'll have the opportunity to exchange them if you don't like the tone you get. Your local DiMarzio dealer may be able to help you in that respect also, YMMV.
