This is eye opening and seriously great information, thanks for posting. I might have that and an additional problem.
The saddle on my M120e is not original, the fella I bought it from said he put this compensated saddle in to correct intonation. I must say the intonation is perfectly spot on. However recently I plugged it in and man, it sounds terrible on the B and high E strings. So now after reading this I’m figuring the saddle slot or the saddle itself is not flat and perfectly mated.
The additional problem I note is this compensated saddle has raised the B string higher than all the other strings, and in fact, I don’t believe any of them are in alignment with the fretboard radius either. Clearly I can’t even whittle the top of the saddle to the same radius because it will lower the strings, when I would also need to square off the bottom too and so my thought is I just need to replace this one.
I have mostly noodled on this fingerstyle and it didn’t necessarily bother me or cause me to notice. When I flat picked is when my picking got hung up and thrown off by the slight difference in string height and I looked down and see the B string way out there which got me zooming in on things. Here look:
I have bone blank saddle, but whittling it down and keeping the perfect intonation seems daunting. Willing to try, but perhaps a new one close enough is better to start with? Secondly, how do you ensure the slot is flat, do you use a small router or some other scraper tool? Tight working area lol
Thanks
