I know less than nowt about guitars, but that seems a decent deal you got there, I expect a new knob (stop snickering at the back) cant be that expensiveCalled up the local waste site to donate a new waxing kit that the wife had never used (still boxed) as they have a charity shop there. Clocked this YAMAHA RGXA2 guitar missing one string and the volume control knob. Asked how much and bartered until I scored it for £37.50. He said he’d seen one used on eBay for £100 but they were obviously there to recycle used equipment primarily and to make some money but still provide a bargain so they’d marked it at £50 but we’re happy to haggle. When I checked eBay they were £700 plus when new and still selling for £240! Result.......not selling though but still pleased.
