The blue is original. Here's what I found in the file:
top: Flame Maple
accent: Walnut pinstripe
body: Maple
neck: 3-piece Maple with 2 Walnut pinstripes
scale: 34" long
fingerboard: Ebony
inlays: none
pickups: MXY
controls: Essence (volume, pan, filter, mono output)
finish: Sapphire
originally made for: Steve's Quality Instrument, MA
birthday: September 22, 1993
I love the blue finishes we do. That one is done where we seal the wood with clear first, then paint with the tinted paint, then more clear. It makes the figuring totally 3D and it's reversible if you want to go natural later.
