Here we have a boxed, hardly used set of schaller M4-90 light tuners / machine heads. 4 in line, Right handed.   Box is marked from storage but everything’s there.    I’ll consider a deal if you want to also purchase the matching 3D-4 roller bridge I have listed separately here:   Currently £79 but out of stock on Thomann.    P&P will be around £5 on top.   Cheers!
