They were labeled Moog style knobs on the reverb store I found them in. So that is right in line!Cool neck! Is it a Warmoth?
I like the first set of knobs, I've seen them called "synth pointers" on Small Bear Electronics.
I have always wanted a Rickenbacker, then I played my brother-in-law's 450 12. I love the body style, but the neck was a little cramped for my fingers. The "cresting wave" body shape is cool, a 620 is still on my wish list, but those Rosser bodies sure make it tempting to build something with a 1 11/16 nut width.
