Bartolini 57J1-L Bridge p/u
I have a brand new/never used Bartolini 57J-1 bridge p/u. It's for a 5-string bass. It measures 4.1" wide and will fit a Fender Am.Dlx.5. Or...if you're thinking about making your Fender, Lakland, etc. P5 a little more versatile. $60 shipped, ConUS.
Here's the description from the Bartolini website:
This is a split coil hum-cancelling design. It's wound to yield much more "growl" from the Bridge pickup. Very similar in tone to the old Bartolini 94J 4 string pickups, just ever so slighlty brighter at the bridge. Tonally, it has stronger lows and low mids than the typical "vintage" tone.
