have a 2000 swamp ash 3-tone sunburst bass with a tortoise shell pickguard and am putting the thumbrest on. i want to do some sort of mod to it, not quite sure, thinking about three things. 1)sand parts down to make it look like a 60's or a relic? 2) put an active mm humbucker in the bridge position 3) get it refiished to olympic white. opinions.
