There are a number of luthiers who are building a bevel into the upper portion of the lower bout of their guitars. This increases the comfort level of players who normally rest their forearms on the edge of the instrument. The John Pearse Armrest acts in a similar manner and offers other advantages as well. The Armrest helps keep the forearm off of the soundboard allowing the top to vibrate freely. It also protects the guitar's finish against the discoloration and dullness caused by perspiration and abrasion.
