Intonation, am i doing something wrong?

Sign in to disble this ad
I have a warwick corvette and the intonation on the E string is a little sharp at the 12th fret so i took a screw driver to it and cranked the saddle as far back as it can go...and it is still sharp! frustrating to say the least. its not bad, maybe 1-2 lights off on my TU-2 but it is just frustrating me. is there something that i am not doing right?

-thanks

Put a guitar capo on the 1st fret, and check the intonation again, this time from the 1st to 13th fret (F to F). Is it still sharp? Many guitars (and basses) play flat on the open strings, due to a variety of reasons. Also, try a new E string, of course.

everything works together, but the nut slot could be high, it's impossible to tell without seeing it firsthand, but i'd definitely check that

I have the exact same prob with schecter 004. When I told the tech at the music store where I purchased it he said that i was being too picky and schecter would do nothing for me. If I wanted a bass with perfect intonation, I should purchase a bass that costs over the $600 I paid. Or pay them to do nut work. What a line of BS. I am unsure as to how I am going to resolve this. I will call Schecter on monday.

Are you:

Tuning the string using the 12th fret harmonic, then--

Playing the 12th fret fretted, and--

Adjusting the intonation to make that fretted note in tune?

You have to retune the harmonic every time after an adjustment. If that's what you're doing, and it's still not right, put a new string on it.

Was it ever right, or is this a new problem? If it was right and went bad, it's probably the string.

This problem can drive you crazy! Believe it or not, but the simplest answer is to change the offending string.

I was playing and noticed that certain notes didn't sound right. I plugged in a tuner and sure enough, the intonation was fine on the open string and 12th fret, but off a odd spots. Then I noticed the odd spots were on the same string. So I replaced it, adjusted the intonation and no more out of tune notes!

...Or you could go back to the store and let the tech tell you how picky you are, and how your mother didn't love you enough, or some other ridiculous response to a simple problem.

Its not always simple kev...

I have tried several differing types of new strings such as EB's D'addario and cheapie hartkes, all with the same results. I think it is the nut, its brass, and not so easy to adjust the height because of this. I have tried every trick in the book that I can do.
Well see on monday, either way Ill get it worked out.

Be sure that there is a good break angle at the nut and the bridge. Press the string down hard just in front of the bridge and on the finderboard side of the nut. Often new strings form a bit of a hump over these areas and it can cause the string to intonate improperly. So try pressing to create a good angle, retune and try resetting the intonation.

I had a '90s Warwick Streamer that had the same chronic problem with the E string. I ended up hacking off half the saddle spring so as to allow more travel. Worked like a charm (in my case, anyway).

You may also want to consider switching to tapered-core strings. As a general rule, the intonation point is somewhat forward of where it would be with conventional fully-wrapped strings. Roger Sadowsky addresses this on his website but his reference pertains to B strings only IIRC.

Yes, I've found improving the witness points helpful in that situation.
