The Allparts muddy gets a big thumbs up from me, I admit to being sceptical. I think I paid $40 bucks for it and I was shocked at how good it sounds. Specs list it at 30k and it certainly sounds it. A great budget EB0 pickup. The uncovered pickup is ever so larger than the original 60's unit. I used a 60s pickup when measuring for routing and test installation but once the Allparts arrived I had to remove a bit more body wood to get it to fit. The pickup would be perfect for Billy Sheehan builds or turning Epi EB0, EB3, or Gibson SG basses into mud slingers.
