...and the 2-post OP has dissappeared from the thread.
Yet here we are starting the third page without him.
We're such a helpful bunch!
...and the 2-post OP has dissappeared from the thread.
I'm on the other side of Lake Ontario ands deal with the same weather conditions!Folks, I bought a Godin DS-1 guitar in March. When it arrived I had it professionally set up by a superb local luthier. Action was set nice and low which I like. This week, after the guitar sat on a stand for one week without being played, I picked it up and was shocked to see that I was getting a ton of fret buzz which I wasn’t getting for the last few months since I bought it. What changed? The humidity and temperature changed a little in my basement where I keep my guitars. The temperature fluctuated from about 16 Celsius (62.6 F) to 20 celcius (68 F) and the humidity fluctuated from about 45% to 57%. I’m working hard to try to minimize these fluctuations but I live in Toronto where we go from cold winters to hot and humid summers. At any rate, I was surprised to find the change in my guitar and can only conclude that the Richlite board does not expand/contract as the maple neck does. My guitar has not reverted back yet and I’m going to have to set it up again. I hope this isn’t a semi-annual exercise as seasons change. Anyone else have this problem?

Maybe the whippersnappers around here haven't seen such a thing, but us oldsters remember seeing that curly thing inside a home thermostat. That there is a bimetallic strip and its movement is predictable enough to allow use to measure temperature, close or open an electrical connection when the temperature hits a certain point. Now they have solid state thingies that do the same job (they use dissimilar metals but the pairing generates a small voltage rather than moving).Look up "Bimetal" it explains what can happen when a different material is used as a fingerboard.... I'm not saying that it DOES.. I'm saying it can...
A bimetal or thermostatic metal is a sheet or strip of two or more composite materials having different coefficients of linear thermal expansion bonded by riveting, brazing or welding. The material with the larger coefficient of thermal expansion (CTE) is considered as the active component, and that of smaller CTE is the passive component. The active component usually has alloys containing iron, manganese, nickel, or chrome in varying amounts. Whereas on the passive side, invar is often chosen, an iron-nickel alloy containing 36% nickel. Some bimetals include a third layer of copper or nickel in between the active and passive sides in order to increase thermal conductivity and decrease the material’s electrical resistivity [1, 2].
it's such things that can make a guitar that plays great one day, play like a toad the next.... it only takes a very little movementMaybe the whippersnappers around here haven't seen such a thing,
I keep all my guitars in an unfinished basement. I also use a big dehumidifier in the summer and a humidifier in the winter. No issues with the necks what so ever.If you're going to leave a guitar out in any basement, learn to adjust the truss rod. Also, click bait title![]()
From my answer to a different thread (edited slightly to fit here better)
<warning - science below. Mojo free zone>
Hmmmm . . . the coefficient of expansion of Richlite in the X direction (length) is 5.2 micro inches (5.2 millionths of an inch) per degree per inch. So for a 20" fretboard (keeping the numbers simple!) the difference in overall length with a 100F degree temp change is .0104" or an even 1/100 of an inch. And that's for an entire 100 degree swing which hopefully a guitar will never be subjected to. A 25 degree swing would be 2.5 thousandths of an inch. I'm pretty sure that would be imperceptible IMO.
The coefficient of expansion of maple (for the neck) is 2.78 . . . so the difference with a 100 degree swing is 2.78 x 20 x 100 = 0.0056". The difference between the two is .0048 or about a 5 thousands of an inch. That's about the width of a human hair. I doubt that difference is twisting up a neck. I'm not doubting that it's happening - I just don't think that it's Richlite on maple.
A 100F degree temp swing is a ridiculous standard to be judged by and almost all materials show issues at this wide temp swing including wood. Guitars are usually built at ~72F and are generally kept somewhere near that number. Richlite doesn't shrink or swell with moisture unless you leave it submerged.
Maybe it's the fret slots? If they get moisture into them it can cause significant back bow. Or if the maple itself isn't sealed well . . . that can cause a neck to turn into a pretzel in short order.

You shouldn't have to do a full setup. Just adjusting the truss rod should suffice for seasonal movement.My guitar has not reverted back yet and I’m going to have to set it up again.
If you're going to leave a guitar out [on a stand] in any basement, learn to adjust the truss rod.
