Seconded. I'm going to have a stab at installing my new pickups on my bass with the fallback of taking it to the shop if it all goes wrong.I usually restring one or two at a time, based on a fear of losing tension on the neck, but I reckon its actually nothing to worry about. If I was gonna clean the fretboard I would just take them all off.
If you do need to set it up again don't pay any attention to anything I say though. Last time I tried to set my Les Paul up I started off with the 1st string choking a little bit on a couple of the highest frets, and ended up with too much relief on the neck, the intonation messed up, the bridge at a totally wrong height, and 3 times more choking going on. Its currently being setup by someone who knows what they are doing![]()
I did once take all my strings off the bass when restringing as I unbolted the neck by accident (honestly, I didn't have a clue what I was doing) with the strings on and had to do a full setup. Lucky to get away with that, but once you attempt a setup you learn a fair bit about your instrument and can set it up how you like it.
