The Fralin hot pickups are great, I just installed them in my ME1. 13.5 Bridge, 12.5 Neck. I also had Lindy use gold screws and raw nickel covers. They look just like the original RPs! The sound is on par with the 59/09 and DGT pickups.
I have used Unbuckers before, they are fantastic pickups. I thought I would use them for a another project, a hot rod Esquire, but Lindy talked me into trying the Hot. The guitar rocks.
It will be interesting to see what you think of the combo of the Hot with the Unbucker. I think the Unbucker in the neck is an excellent choice. You will probably get some nice split coil tones. Did you talk to Lindy about your plans?
