These are direct replacement pups for bartolini MK1 pups. I bought to put in a Lakland 5501, but I eventually sold the bass before pickups were received. So, the pups have never been used. Asking [DEL]$200.00 [/DEL] $175.00 shipped CONUS. I believe the price of these pickups increased at the beginning of the 2013. Will post pics later.
