Sooo, this stalled! I’ve put together a bitsa and bought a headless Hohner Jack since starting this thread, so simultaneously scratched a new bass itch and reached a reasonable limit of new basses (according to Mrs Turgh).
However, all is not lost - I still have those parts, so I’ll have to build it at some point! But it will have to wait until after I do a slightly bigger build - my garden studio! Once that’s done, I feel the new bass embargo will be unenforceable. Mww hah hah hah!!!!
