Another newbie question: I put a new set of Spirocore Weichs on my upright a couple of weeks ago and have been playing them daily. I've noticed that the G string doesn't seem to intonate properly. The pitch of the octave harmonic is different than the pitch of the open string. If I tune to the harmonic, the fingered notes are in tune relative to the same positions on the other strings, but the open string is off. If I tune to the open string, the fingered notes play sharp when compared to the same positions on the other strings. I think I'll put the Helicore Pizz G string that came on the bass back on to see if it does the same thing. I guess that'll tell me if the Spiro G is bad and I can just order another one. So, is this likely to be a bad string or this just something that exists on some basses and I'll just have to learn to compenstate? Anybody else encounter something like this? A guitar player friend avoids one brand of "hand wound" strings after coming across some strings that just wouldn't intonate properly, so I'm hoping that this is something similar.
