Schaller BM Light 4L CH

The pegs mean you cannot lay the tuning pegs flat to the headstock to make accurate measurements, which makes installing them very awkward. It is very difficult mark correctly where the pilot holes should be, and I personally have made a mess of my headstock and had to buy wood filler and start again. I probably should have been more patient and made more of a plan for installing them, but either way it's not a very user friendly design. I really think Schaller should have a guide on the best way to install these.

Aside from the installation they are expensive light weight tuners that look nice and get the job done.
