My esp eclipse is losing tune while playing. I am pretty sure its the tuning heads they seem worn out because the posts wiggle a bit. What tuning heads can I get to replace them that will fit? Originally it has Gotoh.
you need to twist them round a little till they are tighter then, the Gotoh Magnums are the best locking tuners out there IMO
