Ok, I'm at a loss here, so I figured I'd ask around these parts. A week ago I got a new bass to replace the one beat up Ibanez I used for my first year of practice and, as expected, the strings on it weren't the best ones. I got new strings and today changed them as I would normally do, and when I got the action and all that to a point I felt comfortable I decided to go for intonation. Got everything in tune and tried the tune in the 12th fret, the fretted note was pretty flat next to both the open string and 12th fret harmonics, and as every resource I found online told me I tried moving the saddles more towards the nut. No matter what I tried the fretted 12th fret is still flat. I de-tuned every string before adjusting the saddles and tuned again afterwards, but no matter how much I the saddles The 12th fret is still flat, I got to the point where if I turned the screw one more time the barrel would fall off the screw and still flat. My options here are, either I did something wrong, there is something wrong with the bass or I managed to get bad strings. Please help me here, any questions you have please ask, I need to get to the bottom of this. Technical info: Bass: Yamaha TRBX174EW (34 inch scale) Strings: Ernie Ball Hybrid Slinky (105, 85, 65, 45) Tuner: Ibanez PU3 Clip-on Chromatic (This could be the problem but the results are so consistently bad that I do not think so) I know some really nice tuner pedal or something similar would be the best here, but I can't really afford one.
