Just as soon as I received my new Lakland 55-01 I "immediately" replaced the MK1 pups and preamp. This MK1 Pup's and Preamp are in like new condition. I never took to plastic off the pickups. It comes how you see it in the picture... no knobs and you will need foam to put in your pickup cavity's. To make the install easy I cut the red and green pickup wires in the middle. That way you won't have to solder at the pot posts. Just slip a piece of heat shrink tube over the wires, match and splice the wires, the put a touch od solder on each one, slide the heat shrink tube over the splice and heat it up a bit to shrink and bada-boom, your done! but you'll have to do the same with the battery wires and the two black ground wires. Like I said these are in brand new condition. I will wrap the pup's and pre in bubble wrap and and ship anywhere in the lower 48 U.S. for $100.00. Paypal is fine. Thanks!
