a problem with keeping my uv77bk in tune?
Sounds like it might not be set up right.
Are you having a problem getting in tune? *or staying in tune? *two different things.
If the floyd isn't balanced right, you can spend all day trying to get the whole guitar in tune - you get the top strings in tune and by the time you get to the bottom, they're all flat again.
here's what I do:
Use a tuner to get the guitar in tune with itself - even if it's a bit flat - as long as it's evenly flat, it's fine. *
Make the the bridge is level (i test this by locking the trem and pulling up on the G string until it bottoms out against the guitar - it should be about a 4th if the trem is set right)
Once you have the guitar tuned to itself, lock it. *Now go in back and turn both tremclaw screws about 1/4 turn (a little more if the guitar is very flat, a little less if it's only slightly flat). *Then check the tuning . *it should be closer to "440" tuning. *
If it's real close just tune the guitar and you're good to go. *If it's still flat, turn a ltitle more on the claw screws. *If it's sharp, then you went too far, loosen them a hair. *If the high-half of the guitar is close but the bottom isn't, just tighten the trem screw corresponding with that half of the guitar. *(i hope that makes sense)
Hope this helps.
PS: *i leave the back cover off my guitar because i do this at least once a month. *Sometimes with new strings you have to make an adjustment before the strings are fully stretched out, and then again after they're stretched.
