I play jazzes and like a slim neck and I find my Yamaha 415 easy to play, I think the nut is 41mm , which is the same as my precision , hope this helps 🙂
Very nice Frank , and I like the grain in the wood ☝️, it’s very similar to my one , I think the block inlays may have been an extra on request , because when I ordered my natural finish one (I didn’t want markers) I was told they come without them unless it’s a signature model
I’ve had a set of those on a jazz for about 6 or 7 years, they did take a while to break in , probably about 6 weeks on and off, then they really mellowed and are even better now, I think I paid about £10 for them, bargain 🙂
I can’t help with roundwound strings as all my basses apart from 1 precision have flats, or tapes, I think @jazzyvee uses rounds, maybe he could advise 🙂
Might be worth asking if they will post, I really liked a precision a while back which was collection only way up north, and I asked if they would post and they said yeah sure 🤷♂️
