What process is used to check the intonation of a bass? I believe that you check the harmonic on the 12th fret and then adjust the length of the string at the bridge appropriately. But I am still a beginner, so I just want to ask those in the know. I could take the bass to my local guitar store, but I have seen the people there and I suspect that I might be the best one to do this.... Is there a website or link that goes into greater detail on this? I imagine that learning this myself would be a great way to become more familiar with my bass guitar.
