My old band recorded a demo of some of the covers in our set as a marketing tool for getting gigs. Two of the tracks were recorded with my old 4003s. Listening to the rough mix, straight after the session, the Ric sounded great, really growly, definitely a Ric. However, when it was mastered and the final product was delivered, all that Ric-ness had disappeared, just a generic bass tone. OK, it was probably more like the tone of the original tracks, but all the character that I liked was gone . The guy who recorded, engineered and mastered it - a bass player!
