I'm not that experienced with setting up a bass but willing to learn. I’ve noticed fret buzz on the E and G strings around the 8th to 11th frets. Is this a coincidence and saddle height issue or do I need to adjust the truss rod? It’s an Ibanez Geo 180, so a very budget (but decent enough) bass. There is also a weird vibration on the E string saddle that I can only fix by wedging a bit of folded paper between it and the A string saddle. I’m probably going to replace the bridge. The reason I’m spending so much effort on such an entry level bass is because it’s the first bass I owned and was a present from my wife.
