What's the difference between the Vigier Excalibur Special and the Supra? Is it just the flamed maple top on the Special? And how will that affect my tone? I'm guessing it will make it more upper mid-rangey, but I don't know much about guitar wood. Also, what body wood (alder, maple, ash) will sound well with a flamed maple top?
You are correct the main difference between these two models is the addition of the flamed French Maple top. The addition of Maple helps with the high end tone, becoming slightly more 'fuller' or 'rich'.
