Tenor ukulele, peg head geared tuners or geared machine head tuners?
Just one point regarding balance, ukulele will be fitted with K&K twin spot pickup.
From the point of view of keeping your ukulele in tune? Get open geared tuners every time. Peg head geared tuners are still geared fast. Peg heads are for fashionista's or Masochists.
Pegheads and friction tuners are my favourite. I don't mind geared tuners but they don't look as good on a ukulele IMO. It's also easier to restring without having to wind/unwind forever.
I've been told that tenors don't stay in tune as easily with pegheads / friction tuners though. But the tenor I have on order will have friction tuners. I had the option so I jumped on it. I'm sure it will be fine.
