strings buzzing

[dvh]

I had a Godin A4 profressionally defretted and set up with a set of TI Jazz Flats. After a day or so I noticed the E string buzzing against the fretboard when fretting at the first and second frets marks.

The action was extremely low. The bridge is not adjustible on these basses (Piezo pickup) so I did a truss rod adjustment and took out a little relief on the neck. That fixed the E string problem.

What I've been noticing, though, is that at some positions on some strings along the board unless I press really hard on the string I get a buzzing, "mhahhy" note instead of a clear ringing note.

I'm not sure what's going on: technique? - I played an SR400 fretless for many months with no such similar issues - strings on that one were Fender flats; strings? - I've heard the TI Jazz Flats are very flexible - too flexible?; technique? - but I'm not doing anything wrong I'm aware of - like I say, never happened with the SR.

Maybe I'll post this is strings as well but thought I'd start here.

Thanks!

You should be able to get a great tone out of that instrument with TI flats. That's what I have on my Godin AcoustiBass (forerunner to the A4).

There may be some problems with the flatness of the fingerboard - it needs to be truly flat. And it should have a tiny bit of relief - certainly less that a buisness card's worth. Though the bridge is not adjustable, it is possible to affect the string/fingerboard clearance - same effect as raising or lowering a bridge. You should be able to get lots of "mwah" from the instrument, or much less if you don't like that sound.

I suggest taking to the folks who did the fret removal for you and explain the problem. They should be able to fix it.
