Ok so I just got this pickup installed in my Esquire partscaster last night. What can I say about it.....its just sweet! Cleans are sweet, midrangy but not nasely, good bass response, and treble that is useable! Very balanced and responsive, it really has some character quite unlike anything I've ever played. Now that being said I have never played alnico3' s until now. With some dirt it sounds jangly like that old school rock and roll, I don't know to else to describe this thing but i really dig it! If you have any questions I can try to answer them haha, but that's the best description I got. Wonderful work Rob, bravo man!
