    Gotoh Locking Tuners

    Posted by Mr. Joe Bangles on Jan 18, 2024

    These are great, vintage looking tuners that stay in tune wonderfully, and look right at home on my 40 year old Gibson SG. The price was fair, and shipping was quick, I'd definitely order from Philadelphia Luthier again.

    Extremely happy!

    This is what I exactly needed. I have a few other Gotoh products including a tune o-matic bridge and tuners for ES-335 I replaced 10 years ago. They are all so precise and I was confident before receiving these Magnum Locking tuners. When I received I was extremely happy because these tuners were even more than what I expected. They look great, keep tuning extremely tight. Installing them was super easy. I will stick to Gotoh's products when replace bridges and tuners. They never disappoint me!

    Not only is this a great product, helping my Les Paul's infamous G-string from going out of tune, but the customer service I received from PLTS was incredible. The post office delivered my tuner to the wrong place, and eve though they admit it's their fault, because I didn't buy "insurance" at the time of purchase, they made no effort to pay me back for my loss. I let Kenny know and he didn't bat an eye. He sent me another set at no charge. I jumped through hoops with the post office, but Philadelphia Luthier was a dream to deal with. I will definitely be ordering from them again.
