I'm new to all this Posting and Forum stuff, I usually don't do stuff like this but, What the Hell!! Right?? If someone can help with this "Pain in the Ass!!" This Bass simply, Does Not Tune!!I've looked at just about EVERY possible culprit. Bridge, Nut, Machine Heads. Measurement from Nut to Bridge ( 34" ) Neck, Angle you name it, I can't for the life of me figure out why it doesn't tune up. Closed tuning , fine ex,5th fret A and 7th fret A on D string, tunes fine but then open string, Horendous. Anybody run into something like this ?? The body is ACRYLIC, but should that matter??

I wouldn't think the body material would matter unless you can physically see the bridge lifting from the body?

Are the machine heads good quality branded items? The only thing i can think of is that the machine heads are slipping or have bad gears? Someone more knowledgeable than me will hopefully chime in with a better response.

Above and beyond that the bass looks fantastic with the LED lighting (y)

Are you saying it holds tune in the fretted positions but not the open tuning? Your post was a little hard to follow.

If it is in tune on the fretted notes but the open string is out you have two probable causes.
1. The nut. Is the nut lose or the string slots carved badly? The nut is essentially your zero fret so this being wrong would effect your open string.
2. Intonation. If you tune it accurately at open string and it's then out up and down the neck and vice versa try adjusting the intonation with a good tuner. The bridge saddles should slide back or forward with a screwdriver allowing you to lengthen or shorten the string until it's fixed.

Whereas if it's mostly in tune but just the odd place is out you might have some high frets. Get a fret rocker to check.

If it does tune up but then promptly goes out again something is slipping. Systematically check each possible cause.
E.g. is the bridge solid, nut, strings tied to machine heads correctly, machineheads ok, neck on tight enough and not flexing/moving
