Booli,
If the intonation is off then more than likely the fret's are miss placed for the scale of the instrument or maybe the whole scale is wrong and you really can't fix that without a new neck. I also use a wide neck my normal is 38mm and my wide for large fingers is 40mm. It seems all ukulele's have a problem around the 7th fret dieing out in tone a little but remember it's a small instrument and we are demanding alot from it. Don't get me wrong we can get good tone up the neck 7th,9th.12th frets but we have to work harder voicing the instrument and with proper bracing.

Hi Mike,
Thank you for the reply.
It sounds like you are aware of the problem and conscientious about minimizing it. I know that good intonation is possible, and even with an inexpensive instrument as well. It's been my experience that the
Magic Fluke Company (
http://www.magicfluke.com/) has achieved near-perfect intonation with their Flea and Fluke lines of ukulele.
I have a concert Flea with the polycarbonate fretboard, and a tenor Fluke with the rosewood fretboard, and the intonation is absolutely perfect up to the 9th fret, after which is is about 5 cents sharp, and at the 12th fret and thereafter, it is a steady 10 cents sharp, but since I rarely play chords at or above the 12th fret, this level of intonation accuracy is not a problem for me.
It seems to me that most of the problems with intonation that I've seen are simply because the bridge, and therefore the saddle are in the wrong place, even 3mm too long or too short can screw with the intonation. If the tenor fretboard is made for a 17" scale but the bridge/saddle is 17.25" from the nut, there is no way to fix the intonation without moving the bridge/saddle closer to the nut.
It simply baffles me that certain uke makers cannot seem to understand how to use a ruler and measure properly.
Sorry to mix metric and imperial measurements, I have not yet converted the scale lengths in my head to their metric equivalents, which I prefer instead of trying to figure out 16ths" or 32nd" divisions.
This problem is very common on instruments that sell retail for $100 or less, regardless of scale length.
If the intonation is off by too much, and unless the instrument is a one-string ukulele, the tone could be like the sound of angels, but without proper intonation you cannot play chords without serious problems with fretted pitches being accurate along the neck.
For example, the open A string should register at 440hz, and then the 12th fret of the same string should be VERY close to 880hz, but NOT 720hz or 970hz. I have played many instruments on the shelf at big-box retail stores and if the intonation is off by too much, altering the nut and saddle may not be able to fix the string geometry, especially if the bridge is misplaced. ALL of this can be remedied and prevented during manufacturing, but many ukulele makers in this range of the market seem not to care about this problem.
I like a wider neck as well. So far what you have said here all sounds like very good news to me.
