This is a set of 4 chrome bass tuners from a bass project. I am not 100% of the make of these. They could be Schaller or just a set of generics. Either way they are hardly used and turn and hold their tuning very well. They are only up due to switching to a black set of tuners. Throwing in an extra tuner from a MusicMan bass. Screws and headstock ferrules are included. Also these tuners are reversable to righty if need be. They are currently setup in the lefty direction. A great inexpesive yet quality set for a bass project !! $30 shipped within the lower 48 USA. Thanks for looking !
