That is a looker. I wish these had fingerboard inlays. Wait, no I don't. I don't need the temptation!
I'll have to confirm in the file, but this beauty sure looks like Flame Walnut to me.
This has been on Ebay for a while and certainly looks like Walnut to me, too. Nice top.
This is one of my old basses. Actually this is the only one I wish i had back. I checked the serials against my records. I thought it might be my old one because I put those custom knobs on it. It is flame Walnut like Mica says.
