This client doesn't like the traditional raised pick guards and associated hardware found on many mandolins. So we installed a faux tortoise shell directly onto the surface of his Eastman MD 505 A-style Mandolin in classic sunburst. Happy to say there was no significant affect on the tone of the instrument and he was pleased with the function and the aesthetic of the pickguard! The top was refinished on this 70's Gibson below (at the request of the owner!) and we used a clear pick guard to replace the original which had left a patch underneath that wasn't so UV affected. Overall a neat effect as it looks as though the pick guard is made of the same wood as the top just a slightly different hue.
