hi i have tha same bass serial no 174 .1982 model with foot controller. i have owned since 1994 purchased in UK from Andy`s guitar shop in Denmark St London for £800. mine is shown in the ULTIMATE GUITAR BOOK by Tony Bacon, published by Dorling Kindersley in 1991. some info in book but not much,.. i use the bass occasionally, works fine usually, sometimes it forgets its programmed sound on odd no`s (mainly no 10 and 11) some years ago i had a electronics expert make me up a longer feed lead to foot controller and that cost £100..... however no further prob`s there. i have been offered £1500. for the bass and matching case etc, but am not selling. hope this is of help as your .post is 5 years old, (only just joined the forum) i believe only 4 were made for sale?? i might be wrong. regards Syd. ps pictures to follow.... my tech ability , not great
