Planning peghole drillings will always be complicated and doubtful, and that's why we developed this jig!
It's made of aluminium, with a black anodized finishing. 35mm spacing.
Package goes with the respective bushings (for Acoustic - 6.5mm).
Check it on use on this YouTube Video.
If you only need to work on classical, here's the jig for it,
but if you want to work on both, you can purchase just the bushings here (10.3mm).
