At the moment, nothing I'm afraid. My specific point of interest is research into the SB basses as I'm planning on making one this year - most likely a Black n Gold. The local
kansalaisopisto ("civil college") are running a woodworking and metalworking course this summer, so I will be replicating the bridge whilst I'm at it. I tend to think into things WAY too much, so in addition I will play a little with brewing pickup and preamp configurations. I doubt the bass will end up being a true SB in anything other than the wider look, but it will definitely wear its heart on its sleeve. I like unlocking these little challenges.
As a further development from this, I may make a small project run of retrofit replica bridges if there is enough call for them. Many of the originals have pretty much petrified by now.
