I bought the BigRedBass as a consignment piece at a local store. Really fine shape, but of course the brass bits needed the usual TLC.
So in the process of restringing and cleaning/oiling the ebony and the frets, it was obviously the right time to pull the bridge, field-strip and polish and lubricate. No big deal, I'm a reasonably (!) intelligent person.
Looked great when I finished, put it back on, strung it up . . . and it was on backwards ! !
So, BEFORE you do this, make yourself a little diagram where the saddles were and WHICH way they're facing !
