So I'm planning on building a Wal mkII copy. Currently even second hand Wals are out of my price range, and I know a big part of the sound of these basses is the pickup/preamp combo, so after looking online at who makes the closest p'ups and pre's, it seems those will be about half the cost of the project. I'm thinking of getting a warmoth paddle neck and building the body, as necks scare me and I've already built a body for a guitar a few years ago. I'll be getting help from my girlfriend's dad and his workshop, so it shouldn't be too difficult. I've also used CAD to create scale templates to get the body and headstock shape right. As Wal use their own knobs and bridges I'll have to use parts that are 'close enough', but hey, hopefully the project should save me £2,000-4,000 as opposed to getting a real one. I'll probably be around here asking for help as the project progresses, and I'll update as things move along.
