I have scored a used Roscoe Beck. I know that this bass is higly regarded here at talkbass. i would like to know something about: -i have heard the sample on the fender website where the RB is recorded with a good jazz bass sound. Is this bass capable of the Precision thump too? i am referring to Jamerson-Duck-Prestia type of sound. -Is there an outboard preamp which enriches the tone of this passive chamaleon? have you ever tried it with a sadowsky preamp? -referring to the B string, how can it be judged? -is this an heavy bass? -is the big fat neck stable? thanks!
