When I listen to people like Zakk Wylde and Adrian Smith, I can hear a really wide, slow and even vibrato. Do things like string gauge, guitar style, and neck width affect this? Because a lot of people associate fixed bridge guitars like Gibsons with that. Does anyone else use this vibrato? Because with my RG, with its very thin neck, after I finish a fast passage, I instinctually use a quick vibrato. Any comments here?
