Thank you for viewing. This is a listing for GOTOH GB640/L4 Nickel tuning machines. I purchased these previously to lighten the headstock, but they didn't make much of a difference compared to the standard tuners, so I put them away after opening the package and taking out one tuner without installing it. I wiped the removed part with a cloth to remove fingerprints and put it back in the package. This is a nearly new item, and you can purchase it at about 20% off the regular price. Don't miss this opportunity. Thank you.
