From time to time, you might need to adjust the action and/or intonation on your bass. Or you might want to make some other modification such as changing a pickguard or upgrading your tuners.
What tools do you need to do this?
There seems to be a zillion different “Musician’s Tool Kits” out there on various websites! All sorts of kits with any number of different screwdrivers, wrenches, hex drivers, etc. of all sizes, and it’s tempting to buy one of them, thinking it’ll cover everything. But unless you have a number of guitars and/or are planning to open a luthier shop of your own, it’s probably a waste of money. I just spent the morning looking at a lot of these kits, from all over the web.
My “Squier Vintage Modified Jazz Bass” came with a hex wrench for adjusting the truss-rod, and a smaller one for adjusting saddle height.
The smaller hex key that came from Fender appears a bit too loose, and I’m concerned that it may get rounded off. There are no markings on them but it appears that the larger one is 4mm, and the smaller one may be either 1.0 or 1.5mm
@JoshFossgreen could you ask your father what size that one may be?
I know everyone’s situation is different, but in my case, all I need is a small Phillips screwdriver (perhaps a #0) to adjust pickup height and a larger one (perhaps a #1) for everything else. It’s crazy to have to buy an entire set of screwdrivers or hex wrenches in order to get the one you need.
I finally found a good source for individual quality screwdrivers in various sizes:
They also carry individual precision hex drivers in various sizes:
HTH someone out there.
All best, Joe
