There are two types of laminated wood.
The better of the two is layers of real tonewood glued together. Many high end classical guitars are laminates. These guitars can sound awesome. When Martin was making some laminates, such as the DM and D1, were made this way. The DM, for example, had three layers of Mahogany.
The LXM is high pressure laminate, which means particles of wood pressed together under high heat with special resin and given a “photo finish” to resemble real wood.
How do these sound? Not great, but passable. I bought a Martin LXM for my granddaughter and it's fine for her as a starter guitar. At 10 years old, it's also the right size for her, which is mainly why I got it. If she sticks with it, I'll get her a real wood guitar someday.
Some of the other Martin HPL models are full size, but they all come with electronics, so the sound is different. Electronics can cover up all sorts of sins in the how-does-it-sound department.
Hope this helps,
: An LXM is made from laminated wood.......
: So, my question is that....
: How does Martin laminate compare to nonlaminated wood... when it comes to sound ?
