It depends upon what sound you are after. I put one in my Frankenstein bass because it was cheap and I'd read good reviews. It sounded bloomin' luvverly - loud, edgy but perhaps not as organic as some of the trad tones you can get from some P pickups. Because the Frankenstein is so good, I then decided to change it for a Fender Custom Shop 62, because I perceived these to be the best P pickups (and one came up at a good price, of course ). Yup it sounded great but, for the job in hand, I miss the aggressiveness of the Entwistle and will be changing it back again soon. To me it sounds like the SD Quarterpounder but more so.
