Re: maple laminates
Advantages can be: Nice looking top if you get one flamed or quilted.
Neutrals: If you get a thicker top (typically about a quarter of an inch is enough to make a difference) It can add a bit of brightness to the sound. This works really well on mahogony-bodied guitars, which is the classic les paul configuration.
Disadvantages: Cant think of any. Could push up the price of the guitar, thats about it.
