So I want a fretless precision (love the way they sound on the last couple fo deftone's albums). I've got a neck coming from warmoth and an excellent tech to do the work. Here's my question. I've decided to use a cheap donor bass for the project and upgrade things like pickup and hardware as i go (pickup first). what cheap p should i use? I'm thinking Squier P, Fender MIM P, or Essex P. Let me know which one you would use and why.
