What are the main differences between cedar and mahogany for neck construction? I understand cedar is lighter but mahogany is more stable. Is that correct? Acoustically what are the differences between the two, if any? I build classicals if that's a consideration. Any insight would be greatly appreciated.

Thanks!

I find Spanish cedar more stable, less prone to movement. It handles moisture better than mahogany and does not warp. Though, decent mahogany is not necessarily unstable, just a bit less stable. Mahogany is stronger, though cedar is plenty strong for a classical, so it is a moot point. I like cedar for its workability and lightness, and I feel for a lightly constructed classical (which is what I make), it is the best choice.



best wishes,
Joshua

I think mahogany is probably a little stiffer and stronger but the cedar is used quite a bit for classical. I have even used cedar for a small steel string but I prefer mahogany. I really don't know which os more stable but I'd bet that both are fairly stable.John How38467.829849537

For what it's worth, I play a GV Rubio "Torrez" with a cedar neck. All of the above I have found to be true with one additional point; cedar is so light, the guitar "feels" better on my leg. Less prone to having the neck side want to "fall" over.

It's hard to explain but suffice it to say that although I am just beginning to make guitars, I am making the necks (3 of 4) with cedar. The fourth is mahogany and I can feel the weight difference already.

Both woods are acceptable for a classical guitar. However, I use cedar from Brazil called Cedro Rosa. It is very similar to Spanish Cedar. It has a pinkish or reddish hue to it and a very nice aroma as well. I have seen the quality of this wood diminsh over the years and it is the next one on the hit list from the Brazilian government. Mahogonay from Brazil is already on the list and its commercialization in Brazil is already prohibited.   This wood (cedro rosa) as well as Spanish cedar is light but very stable. I have had no problems using it on any classical guitar. A bonus compared to mahogany is that the cedar carves easier.
