I got these in a massive parts buy, but have no bass for them. I wish I did, always wanted to try them out... but I have a LOT of irons in the fire now and need to slim the herd a little. They measure 9.34k and 10.09k on the multimeter. They are Fender-sized (3.9" and 4.1") and will fit all kinds of basses. A few examples (but not limited to): Fender Jazz V MIA, MIM Fender Deluxe Jazz V MIA, MIM Squier Affinity Jazz V and VM5 Lakland JO5 or DJ5 No screws, sorry. $140 obo shipped to the US Paypal or Money Order. Int'l PM me. I'd trade these for a preamp, maybe. PM me.
