I recently bought a Maruszczyk Frog 5-string, set up with the the standard flats they sell through their custom portal (.45, .65, .85, .105, .125). However I want to switch to TI Jazz Flats. The TI low B is the only string that's a thicker gauge than what's currently on my bass (.136). Typically I'm fine with setting up my own instruments, but I've never filed a nut slot before and I don't have the tools for it. Is it worth it to buy the right file and and attempt this myself? Is it even necessary with a .011 difference between string gauges?
