This is too cool... Nathan East is selling his Series I, and he wrote the ad copy!

This bass has been on the market for a couple of months now. Price started at 25K and continues to slowly drop. It is a really nice bass that will get sold when the selling price coincides with reality.
 
FWIW... I believe the bass is being sold on consignment. The ebay listing shows that is being offered by Rock Island Sound.

is it me or does that fretboard look pretty worn?
