Speaking from my own experience: Wood has a huge impact on tone. I have two guitars that are quite similar, especially the construction and shape. Suhr Modern (alder body, all maple neck, bolt-on, two point tremolo) and Mayones Setius (mahogany/maple body and neck, bolt-on, hardtail). The Suhr's body is actually a bit thicker as well. However, they sound nothing like each other. The Setius sounds close to a Les Paul, and the Suhr sounds bright and lacks the balls of a mahogany guitar. I also owned a Suhr S4 with basswood/maple body for a few days, with Suhr ML pickups in the neck and middle. It sounded extremely bright and extremely dull and lifeless at the same time... So I have figured that I will probably not get another guitar with anything else than mahogany! Maybe I will get an alder strat just to have one, but mahogany will always be my favorite by far!
