Hi, I have a marvellous CV '60 Jazz Bass (indonesia 2023)... It is marvellous, it sounds amazing.
The only upgrade I made are 3 CTS pots and rewiring... good improvement from bad pots.
The only bad thing: tuner machines!!!
I've read a lot of threads but honestly I would like to be sure before buying any new tuning machines set. I do not want to drill new holes.
Is there any of you that have already replace tuners withou drilling new holes? Are Schaller BM a direct drop-in solution? (https://schaller.info/media/ec/a0/60/1730113515/1025.jpg)
Thanks a lot to any of you that helps me.

so I can see an argument for replacing with lighter ones (which usually involves drilling new holes and leaving old holes visible) but I don't expect any of the usual same-look replacements would be much of an improvement, if at all.
