I recently read an article about Jack Bruce. In it, he stated that the Warwick was his favorite bass. However, when he did some stuff with Ringo Starr, it didn't do well with McCartney basslines, maybe because the Warwick is fretless. So, you Beatle freaks.....what works best for their music? Hoffner? Rickenbacker? Gibson? Fender? Or is Bruce to picky?
