I'm planning a new project and I simply can't find the right pickups. I'm making a semihollow adn I want to give it the warmest tone possible. A similar sound to a carvin ac40 or 50 or a rob allen. I just don't know what kind of pickups to use. I don't really want to see any either. I was thinking maybe a peizo pickup would do the trick, but I don't have much experience with them. Can anyone tell me where to get them and would a single piezo pickup be sufficient amplification?
