If I get another bass, it will be between these two. I play rock/metal/punk music. There really is no defined style or sound (to me) for the styles I listed...Fear factory has the one of the heaviest metal sounds and I cant hear the bass much at all. Personall I like it bright and punchy, a nice slap sound is a must. I could care less about string spacing- I don't even know if there is a comparison between these two basses, but if there is, I would like to know some more. In the end its all up to me, but it all helps Ibanez basses have been crapped on by the industry's reviews, and Music man has been hailed. Rumor has it the BTB prestige is a nice bass. Let me know your thoughts.
