Well i like the feel of a worn in neck, my MIM is 6 years old and the back as no wear it feels new and i just dont dig that. I am not looking to relic it i just want a more natural feel . Suggestions that dont require 100 years of playing welcome
Scotchbrite pads work excellent mate. No need to mask up your pickups like ya have to do with steel wool *edit.I just realised that your bass might have some sort of clear coat finish that Scotchbrite could take a year of scrubbing to penetrate.If so,maybe some fine sand paper would do the trick. Good luck with it.
+1 on the sandpaper. MIM's AFAIK have a poly coat on the back of their necks. I haven't done this personally as I usually clean the neck every 6 months to a year or so with gunstock oil. Makes it nice and smooth.
