I notice the catalogue refers to perloid inlays on some instruments and mother of pearl on others.
Is perloid a synthetic and MOP the real thing?
Yes - though since the catalog was published we've discontinued the pearloid inlay material.
I have a bass with pearloid inlays. I wonder if it can be upgraded someday to the real stuff?
Sure, but we like to do it when we're refretting.
