Wow 150g is really heavy! My geared uke pegs with pegbox weigh in at 100g. I find for my daily playing violin I prefer the geared uke tuners. I get very tired of tuning with the uke friction pegs! I have built up a fiddle with geared planetary pegs, and those tune very well and are a bit lighter, but they are expensive and can be hard to set up.
That said, I prefer the friction uke pegs when I am trying new bodies, as they tune up quickly. So they have their place.
Here is the weight of my different pegboxes with tuners:
- Grover 6B tuners 80g
- Wittner Planetary Pegs 75g
- 3D Printed Friction Pegs 50g
- Geared Ukelele Pegs 100g
