The Burpster Posted November 23, 2007 Share Posted November 23, 2007 DH, There is a thread in (repairs IIRC) about a BCer that has got some new pups, and they have an extra earth when output. When he has contacted the maker, they have quoted that the extra earth is for on-board pre-amps with a buffer. I have a rough idea what a buffer does, but my question to you is:- Have you any idea why some new on-board pre-amps have one built in? and assuming that most amps pre amp stages have one, or seperate pre amps have one, what would there be to gain by having one in the bass?
