I believe these "F" Logo tuners are 14:1 ratio and the Fender Vintage standards which I have on all my other ones are 15:1 (?), so not a huge difference. I've read mixed reviews about these "F" Logo ones in the past, but they seem perfectly fine to me. They get where you need to go fairly quickly and hold tune well. They do their job.
I'm still stretching out the strings and getting acclimated to it. Exploring the feel of the Bigsby and testing the overall tuning stability when using it. Seeing what I can get away with without it going completely out of whack.
The Tech did a marvelous set up before it shipped though. Really impressive. Pretty much as I like it action wise. I just had to raise the high E a hair and was off and running. No annoying "Pings" from the nut (I hate that. It's the first thing I check for with any new guitar). One funny detail: I noticed that the neck backplate was on upside down and thought, "That's weird, never saw that before!" So I contacted the shop and it turns out that when he did a slight truss rod adjustment, he accidentally screwed it back on upside down. I figured that's probably what happened anyway
I've been checking out some Tele/Bigsby related YouTube videos for set up tips and this one here by Jay Leonard J is really good. If you care to share any Bigsby wisdom, please feel free!
My only suggestion on the Bigsby installed on your guitar is to always minimize the break angle at the bridge. Friction is your enemy, and the B5 tends to introduce much more break angle than is needed. ALSO make sure your bridge is high enough that it can rock through your FULL range of vibrato. It currently looks fairly low, but if set up correctly, you should be fine. If it can't rock enough, then the strings are forced to slide over the saddles causing friction and possible return-to-tune issues. My only other suggestion is to try a Reverend "squishy spring" that significantly changes the feel of the vibrato - much more sensitive to use. Most people prefer them. With these springs, you kinda go from using your arm to using your wrist.
Don't just "put up" with any tuning issues. They are NOT inherent in Bigsbys, but are common due to poor setups. If you notice single strings not returning to pitch, it is likely an overly-tight nut slot on the offending strings. A simple polish is enough to cure it. NO, YOU DON'T NEED LOCKING TUNERS OR NUT LUBE! If you notice all of the strings going sharp or flat and not returning to pitch, your bridge is likely not rocking enough and the strings are slipping over the saddles. Make sure the bridge stays centered when the arm is at neutral. Sometimes with excessive break angle, the strings can actually push the bridge gradually forward so that it stops rocking. There are fixes for that as well that I won't go into here.
I am sure your instrument was set up well. You may want to take measurements now so that you know what the best setup settings are. Enjoy that beautiful guitar!!
