So I've been mulling over replacing the tuning machine heads on my P bass. The stock ones are old and can't keep the bass in tune after 30 mins of jamming. I have a 2010 MIM model and I've narrowed it down to these 3. Hipshot HB7, Schaller, or Gotoh FB30. The hipshots seem the most practical since they're a drop in replacement without having to drill new holes but they're the most expensive. I like the schaller and gotoh ones since they look like the classic 70's tuning pegs, though the gotoh tuning pegs look a lot longer than the schaller and hipshot ones. Any suggestions? Thanks
