I've had all these, and more... Btw, I'm very impressed with this forum, this thread, great info and atmosphere ;-) I had a pre CBS dead mint Dakotah Red Mustang with case (part traded in on a 1960 Strat before those things went completely crazy), a competition Blue Bass, dead mint, can't remember the year (and that was the second one, the first I bought out of the Sunday paper back in the early 90's), plus several Musicmaster, Duo Sonics, and two Musicmaster basses, evil little things that they are... One that sticks in my mind I bought in the parking lot of a discount smoke shop on the ID/WA border, was about a '62 Duo Sonic, in Desert Sand, the finish in an amazing state of "crackelure", and the icing on the cake was when I found out Jimi used to have the same year same color guitar before he got a hold of a Strat, except the finish on his wouldn't have looked like parched soil, but he would have liked that...
They are awesome guitars, not the biggest ego boosters as far as guitars, but whatever. And like (I think it was Qantum?) someone said, pickup combinations/tones you can't get anywhere else.
A little Mustang trivia... back in the 80's I went and saw Clapton, and The Fabulous Thunderbirds opened for him. Jimmy Vaughn played a Mustang their whole set, and that thing had totally killer tones on tap, some killer twang there! I could see him sliding those little switches, I still remember that and I don't remember one thing about Clapton's playing...
