Brazilian rosewood has a sound like no other.  When you drop these rings on a table surface they chime a note.  These are the most musical sounding rings you can get. The grain is cut with a horizontal orient for strength and stability.
Nothing but brazilian rosewood will do for some guitars.  It is the perfect choice to finish off or put your personal touch on a high value guitar.  Sometimes, just installing a set of these can take the fear of playing your guitar away! It doesn't hurt that you get to look inside the pickup cavity while you're doing it and photograph the process for posterity! Who doesn't want to do that!  You will love the way these rings make your guitar look! THEY ARE WORTH THE PRICE and a super way to enhance the value of a collectible guitar.
