I got these tuners for a small project. I have this bass for 20 years and it was my first e-bass. A squier affinity from 2004, somehow feels quite decent quality. I have a bunch of other basses now, but the emotional value made me keep it.
I decided to upgrade it a bit and to make it into a fretless bass. I bought these tuners and I had to drill some bigger holes on the headstock as the older ones were smaller.
The drilling was okey, I'm quite inexperienced when it comes to working on a bass. I ended up using a 16mm drill bit and then filed out some more with a multitool until i got to a size that allowed me to fit the bushings.
I basically enlarged the existing holes of the headstock which brought one small problem:
the metal plate of the tuners was in my case slightly too big for the headstock. It probably wouldn't have been a problem if i would have had to make the drilling from scratch, but since I used the existing ones as guidelines i found that the metal plate of the tuner for the G string is popping out from behind the headstock. Consequentially, i cannot place the last screw for that one as it would just be hanging onto nothing.
Which brings me to the one that I consider being the worst part of these tuners:
the screws.
The screws are absolutely terrible. I have plenty of drill tips but no matter which one I used they would strip in no time. They must be very cheaply made. I had to use some other (also extremely cheap, but not as cheap) screws i've found in my toolbox.
Overall I like the tuners and they do the job.
