Maple is a very nice tonewood, both visually and tonally, imparting a quick attack and decay with nice separation between the notes. This set is dry and ready to use. I recommend letting it acclimate to your shop conditions first. The measurements are:
Back - .130"+ x 5 3/4" x 25" - 2 pieces
Sides - .120"+ x 5 3/4" x 23 7/8" - 2 pieces
These measurements are my minimum tolerance so the wood you get could, but not always, be on the larger side. If you need specific measurements, that will need to be worked out before shipping. Not all sets are sanded, therefore, there will be some saw marks from the milling process. Additional sanding will need to be done by the buyer.
