I have had many of each. I like Brazilian because its so rare, but as far as tone goes, I think its crazy to say one sounds better than the other. Both Brazzy and Indian give a low mid hump that can sound a bit muddy, especially with overdrive. That being said, I play clean most of the time, and I adjust the amp with a little less bottom end when using Rosewood necks. I have made A/B/C clips with Brazzy, Indian, and Mahogany, and let me tell you, it is HARD to tell the difference when you are totally honest with yourself. Even between Mahogany and Rosewood, never mind Indian or Brazilian. If you go PS, maybe blind fold yourself and have someone tap on several different neck blanks of each while listening. Go for the one that rings better, although that may not even matter that much in the end.
Where do Pernambuco and Chaltecoco fit in?
