Hi, I'm from Spain. I read your post and it has brought me memories I want to share with you.
I met well Antonio Ariza. I have a flamenco guitar of him, a really monster of guitar by the way
. He died some years ago. His son, Antonio still works in lacquered (barnizado a laca con muñequilla), technique where he was the best.
He met for example Paco de Lucía and Camarón. He told me that Camarón used to go to his flamenco guitar shop to find some peace fleeing from people who wanted to drug him...They used to talk about life, flamenco, guitars, etc. As I was studying in Granada I used to visit him and always listen to his storys about flamenco, guitar men, singers, etc. I loved that man..., a really close person.
His guitars are unique, with brilliant sound, strong bass but very balanced, you can recognice soon when you hear, only the best woods, made to cross eternity, you can donate those guitar to your descendents about year 4040 with no problem. He sold guitars all around the world, specially France, Germany or Japan, and once I could hear a Masterclass talking with an english man about spanish salads, vinegar, oliva oil...exact amount of acidity... etc
He used to sell a little bit cheap than others. It was fine becouse I could buy my masterpiece guitar just saving money during 8 years, in spite of 10 and because he made me discount...hahahaha.
When I was checking my guitar he told me: 'Po no te kea náh' (in translate: long way to play guitar, man' -more or less-- hahaha.
If you have and Ariza guitar you have the sound of Granada. As I said before, in many pieces of Granada music you can recognice and Ariza guitar form others. Regards!
