solid tuners, but the screws that come with the hardware are AWFUL. I somehow beheaded 2 of them in a row, thankfully I had a parts bin full of tuner screws

Only dislike was sliiiiightly larger than spec sleeves, necessitating the need to ream my supposedly-fitting holes to get them to install.

These are not smooth but work very well. Hold tune long time.

High quality upgrade to the factory tuners you got on your Squier? No.Adequate replacement tuner for a cheap tuning machine that broke on an axe that doesn't get too much use? Yes.Bottom line: It will keep your bass in tune for low cost but will be susceptible to the internal gears stripping or breaking if used a lot. But then, how often to bass players actually change their strings?

Bought to replace 2 broken tuners on an Ibanez bass. Exact replacement, simple to install and perfect fit.
