Bloodwood is an excellent choice for guitars that need a red highlight.  
Very limited supply!

Bloodwood is a beautiful red color.  It is strong and very tough and very well suited as a pickup ring.  These rings will work very well on a Vintage Cherry or sunburst with some red in it.  The possibilities don't end there - they can be used on a guitar with a black finish - either transparent or opaque gloss and these rings will be the highlight of the whole guitar.  For sound, they will lend a little bit of brightness as they are a very dense wood.
