completely within reasonable selling price. 3ply gretsch are hard to move these days. as you know i've been offering my 3ply factory custom progressive jazz set for quite a while now with very few inquiries.
I'd have an exploratory discussion with the clothing guy and feel him out before offering any amount. If the market value is $1000+ and the guy has no clue, I'd offer $500. that just might blow his mind and make him jump in head first.
1st: If you've never heard a vintage RB 20" Gretsch bass drum with an Emad on the batter side, you've not been enlightened. Thump and bottom end for days and if this will be played in a closed and mic'd environment, you'll be more than happy with its playability and versatile tuning range...
