Dead spot ?

[mike not fat]

During my last training I noticed that the sound at the 19th fret on the E string of my Bongo isn't sustaining as long as the others (I never noticed that before). It deacreases fast and in a strange way, being a bit distorded. Is this a dead spot ? Or is it an intonation problem (I far as I know, on the Bongos intonation has to be checked at the 19 th fret, not at the 12 th ) If its a dead spot, are there any ways to make it disappear ?

Thanks in advance for your advices.

>>>and in a strange way, being a bit distorded.

By your description, my first guess is that a pickup is sitting a tad high...pole magnet affecting the string vibration.

Thanks GAV, but I dont think so. The PU are set to EBMM's specification, even a bit lower. And this phenomenon doesn't appear in any other frets, even after n° 19, or strings.
By distortion, I mean that the note is decreasing fast and suddenly going up a very short time before ending ; using a tuner and watching it react makes that obvious.

But I'll follow your advice an check the PU height, just to be sure.

Anyone got another idea ?

Play the note on the 14th fret of the A string. Problem solved!
(Or the 24th fret of your B string or the 9th fret of the D string or the 4th fret of the G string. Take your choice.)

raise the saddle a little and put some relief in the neck, that's what Jon told me for my dead spot I had last week BUT since eturning home I think the climate has re-tweaked whatever was going on. But I am going to fiddle around with it tonight a bit finally.

Correct me if I am wrong, but I would assume that factory specs for pickup height would be dependent on the strings used during factory setup. If you have changed string brands, gauges, or material then the properties of the string would be different, resulting in a perhaps minutely different pickup height requirement. Also, if the strings are new, check the break angle across the bridge and nut (this is especially true on B, E and A strings). Improper break angles can serioulsy alter playability toward either end of the fretboard.

Just tryin' to help...

Perhaps the 20th fret is a little high? Is it vibrating against it and making a metallic noise?

the 5th fret on my gstring has a very short sustain and goes into a harmonicish ring...and i'm pretty sure the 6th fret is whats doing it so you might want to look into that

Thanks for your advices, I'm gonna check everything you pointed out and let you know. As it doesn't buzz or produce a metallic noise I don't think the 20 th fret is responsible for that. I'll try to improve neck and saddle adjustment.
