As the man said be cool, a Warwick NT is an absolute steal at the price, no dispute. But, an issue with the 'crack' could up the aquisition cost a couple of hundred squids to have it sorted, then not so inexpensive. Plus, the new owner would have to explain that away when moving the bass on sometime.
My advice, get it sorted then sell with impunity, or, put it to the Gallery for sorting and selling you get the balance.....Anyway you got it off your chest thats a start.
