I'm selling the machine heads I replaced on my blacked-out Ibanez AZ guitar. Everything is included and I think they're in good condition. They will be shipped in the original box, so it's not black. You can lock them simply by turning the screws on the back, making tuning easy and stable. - Brand: GOTOH - Model: Machine Heads - Quantity: 6 pieces - Material: Metal - Color: Chrome Thank you for looking.
