Here we have a Lakland LH-3 preamp as used in the higher end Lakland basses. Bought these for a project and never finished it. Works great, sounds great. I resoldered the power wire to the board after it broke off, and fixed that flawed design while I was at it so that can't happen again.
It's a 5 knob preamp:
Volume w/passive bypass push/pull
And of course has selectable mid frequency points on the board.
I do have the mounting nuts and the original Lakland push on knobs for it that I will include.
I also have a Lakland wide 5 string pickup as used in the 55-94 and 55-02. This is the 'wide' version used by Brubaker, MTD, and many others. Works great. Preamp $75
Pickup on hold
Prices are shipped to the lower 48, paypal only please.
I don't have the mini switch for the pickup switching, so you'll need an on/on/on mini switch if you want to wire it for coil switching.
