Yeah, unfortunately. I tried to contact Andy G. several times and all I got was a mail with his new band's add, something like: "Nice of you to write to me. My new band blah-blah..." And I wanted to know how the hell they recorded "Saturday...", which guitars and amps they used, since so much energy they release every time I play CD. I have a rock and roll trio playing LP Classic Premium Plus ltd. and singing and so much in love with that great DD sound.
I tried to get myself a Custom, too and I've found one in great shape in nearby Croatia, black from 1975. in protector case, but still don't have that pile of money ($3,000).

Saturday Night Fever is a criminally underrated album! I still am amazed by them to this day, they shoulda been huge...Custom is a 1987, towards the end of the "Norlin" era I've been told...rock on!

I've seen "like" for The Devil Dogs. You're one of the rarest person ever heard of them. My favorite rock and roll band for almost 20 years.
Nice Custom there on avatar!
Cheers!
