I'm thinking about building a custom Carvin bass in the next few months and I really want a P bass tone, so I was playing around with the bass builder for the PB5 five string P clone. Under the pickups section I saw that there was an option for a MM style humbucker at the bridge with an active/passive toggle. I like the sound of a Ray more than I do a Jazz, so instead of an added J pickup in was thinking about adding the big humbucker instead. Any thoughts on this setup? Anyone else have one like this?
