I bought this recently for my EUB which is an old BSX 5 string. This is a snarly sounding pickup system. I was looking for the exact opposite to offset the snarly sounding magnetic pickup already on the bass. In the process of pulling the pickups off of the bridge I broke one. I cut the lead and separated the wires to prevent a short. I tried it on my 4 string acoustic bass and the remaining 4 pickups work perfectly. If you wanna try it out I'll sell it for $30 shipped. Comes with enough double sided goo tape to mount it 2 more times. Don't cover the whole pad. Cut a small square of the tape. It is strong stuff so you don't need to cover the whole pickup with it. That makes it easier to pull it off later without busting them. Comes with all the original paperwork.
