I just picked up an Ibanez guitar and whoever owned it before me had replaced the bridge p/u with a seymour duncan JBJ - I don't see it in the products list - what type (other than humbucker) pickup is this - i.e. what style does it work well for, high or low output, etc. When I plugged it in it did not seem as hot as the Ibanez p/u's in the other positions but than again it isn't set up very well yet. thanks in advance for any feedback.
