Nice. I’ve not seen one in the flesh as it were but watched several demo’s on YouTube. The only bridge’s I was aware of that would adjust sideways for string spacing were the Schaller 3D and I have one on a Vintera which is basically a BBOT with a bunch of grooves on the saddles which is a bit more primitive.
Good luck with your build. I was going to call on your expertise at some point to fit a Status Graphite neck on my MIJ Geddy Lee …. Another Bitsa and the final one.
I’m going to spend more time after this learning to play them better!
