I have another tune-o-matic bridge en route to me right now, black. If I don't use it for this project, It'll get used, no doubts about that.
While I wait the 3 or so weeks for my Bass VI Neck Mk II to arrive, I've gone with the sacrilegious option

It ain't pretty, but at least the nut doesn't go flying off.
Simon - my thoughts exactly. I didnt want to glob the glue on, so I lightly super glued like I usually do and the tring tension pulling to the treble side ripped it off when I tried to adjust the tuning.
Gotta say, the ripping, cracking sound that happened when I tightened the E string was...not something I want to hear again. Thank the bass gods it was only the nut coming unglued. I thought perhaps my shoot-from-the-hip headstock was protesting it's very existence.

She looks good though

I'm proud I got the fender headstock style, not something that will easilty be reproducible with the 3-3 setup I'm planning. But maybe I will spend the next couple weeks thinking about that

Going very bare bones. I know the Warman G-rail hybrid I have in the neck position is a tremendously powerful and versatile pickup, but the way I'm wiring it is just straight into the 3-way switch so that position 1 will be full-bore neck, position 2 will be both, and position 3 will be full-bore bridge, which is the twin loco from Warman as well.
One master tone, one master volume.
And a heart-shaped thumbtack to plug the last hole.

I got a black control plate, so that'll get switched out...and then It's just waiting for the other neck I guess!
