I have a few of these black aluminum knobs that I won't end up using. I call them Sadowsky-style because I got them from BestBassGear.com (http://www.bestbassgear.com/knobs.htm) but I believe they are the same knobs that are used on Sadowsky basses. They look cool; I just don't need them. Two Large and two concentric. Installed once for all of 10 minutes and then taken back off. [DEL]$5.50 each for the Large knobs[/DEL] SOLD $11.00 each for the Concentric knobs (includes top and bottom) Shipping is a flat $3.00 for any order. Lower 48 USA only. No international shipping on these, sorry.
