This winter I purchased a Gitane John Jorgensen model. I've also been fighting midwest/heated house low humidity, which seems to cause problems to several of my guitars.
The Gitane is plagued by fret buzz on the first string, sometimes on the second string, which varies in location and intensity with variations in humidity. Note - not the real nasty fret buzz that makes a guitar unplayable, but just the kind that seems to muddy the sound, distinct from the clarity higher up the neck at say the 18th or 20th fret. I'm reluctant to take it in to have any permanent adjustments made until later this spring when the heating season is over, and I can see how it behaves in "normal" humidity.
Supposedly the Gitane has an adjustable truss rod. Since I don't see a plate on the head, I assume the is accessed through the sound hole. Though it looks like it's behind a brace just "north" of the soundhole. Any one know what tools are needed? I'd expect a 1/4" ratchet with extender, and a normal or deep socket, or an allen head. What size, does anyone know? I assume righty-tighty, lefty-loosey, normal threading.
Also I see much discussion of replacing the bridge with something a bit higher, giving 2.5-4.0 mm string height 1st string/14th fret ( or is it 12th?). Are the guitars all shipped "wrong" for the aggressive picking style of gypsy jazz, to meet "market" expectations of low action?
When shimming as a temporary adjustment, do you shim equally under each foot of the bridge? This would seem to promote better and more equal contact of the bridge feet with the top. Though one might only need to shim the high side to get more relief for the first string.
What about replacing the fixed bridge with an adjustable bridge? I've seen at least one sel-mac guitar with an adjustable bridge as used with most f-hole archtop guitars. This might be a good alternative in varying humidity and while finding out what action height is best for you.
As a permanent solution, seems a new Dupont bridge is recommended, and not really that expensive. Anyone have a set of bridges with varying heights in liew of an adjustable bridge?
Any thoughts welcomed. Thanks -
