In the never-ending quest to mess with things, I (obv not actually me) have taken a Seymour Duncan 5 string (https://www.seymourduncan.com/single-product/70s-music-man-alnico-5-5-string) out of my MM USA SUB . I have also taken the Nordstrand 2B-MM preamp out (https://www.bestbassgear.com/nordstrand-2b-mm-preamp.htm).
Don't be sorry for me. It is full of Bongo electrics now.
Pickup - £80
Pre - £80
I also have a black (b/w/b) scratchplate and a white (w/b/w) scratchplate. £20 each
Fancy them you know you do.
Geddy Lee's big book of bass - £35 + whatever it will cost to post. It is not light. Or small. As the title suggests.
