Hey guys, I have a new Stewart MacDonald 5/16" hex truss wrench that I bought and used once when I owned my Gibson Thunderbird bass. No longer have any need for it as I don't have any guitars with the corresponding truss rod. With shipping these are $18 or $19 from StewMac. Save yourself $5 and get it, new from me for $13 shipped. Paypal is preferred. Thanks!
