Any shape any size any color and design any finish.
All I need is a pdf or cdr of the pickguard you want and a picture of the design and I can make basicly anything.
Metal, wood, plastic.
Wood is the best though.
I use birch. It has great high and low EQ qualities and does not warp to bad at these thicknesses. Any thinner then 1/8 inch the wood cups real bad.
