I am an amateur guitarist and collector of interesting instruments. In May 2024, I bought a Takamine EG 236 SHB guitar with a large Dreadnought body. It was a short series produced in 2011-2012 in Korea. On the day of purchase, the guitar was already 12 years old, but it was a brand new instrument in its original packaging. I bought the guitar with the intention of using it in a tuning lowered by a whole tone - from D. The original 1:15 tuners did not ensure good standing. So I bought Gotoh SGL510Z-L5 3L / 3R Tuners G from Thomann. Takamine went to an excellent luthier, Lewicki Custm Guitars, who "improved" the factory :-)). Gotoh tuners with a 1:21 ratio and D'Addario Flat Tops Light 12-53 EFT16 strings do their job perfectly. The guitar with original electronics has the sound I expected - strong and very deep. I recommend Gotoh keys for such experiments :-)) Jacek.
