I've had trouble trying to
not use a string tree, but never a problem with a string tree.... the nut is the be-all and end-all of the issue, most of the people making them follow the "rules" for some reason. I make my slots wider than normal, as long as the back angle is steep enough the string
can't rattle - you also want the bottom of the slot to be round, not square, and the sides absolutely parallel. Don't give the string anything to rattle against, and it won't rattle. :icon_scratch: If it's sitting (perfectly) in the bottom of a (perfect) round slot, what
can rattle? :icon_scratch:
A 10X jeweler's loupe or an Optivisor is a
big help. Especially if you're an old blind coot like me; there's also no reason I can see that the heights of the slots should be 1/2 the string diameter (Rule # 7), then of
course your strings would pop out on those violent step-and-a-half bends at the nut - I make my slots cover the whole string.
Trees don't have to be dorky-looking, you can make your own outta... stuff, or just "find" some thing:
The seven-string needed three strings covered so I
had to wing; that's not a real pick either, it's... two bigger picks laminated together and winged upon.
