Questions about locking tuners on an Ibanez RG7421
Hi all. I've been doing some reading about locking tuners and I think I'll put some on my RG7421 seven string. The stock tuners are Gotoh standard die cast. What I'm wondering is does anyone know if there's a locking tuner that will fit right in the stock hole without having to drill it bigger? And if so, where could I find them?
More generally, does anyone know the dimensions of the stock RG7421 tuner holes so I could check the specs on various locking tuner models?
Anybody done this before? Experiences?
It looks like Warmoth would sell me the tuners individually, so they may be the place I'll go. But they only carry the Schaller mini locking tuners I believe, so if they don't fit or would require a lot of modification then that wouldn't be the best option.
Any info or experiences appreciated!!
