Re: what year did the js1200 come out?
I love it. I just got that as a fathers day gift, and I should have bought it myself a long time ago. It's given me so much more control over my tone. If all my pedals were stolen, it would be top 4 to be replaced. They'd probably be replaced in this order.

After that, the pedals all sort of add effect. those 4 give me most of my tone.
Never played around with the Vox amps, so can't give you much help there. But I love my AVT20 + 4x12. I can play small - medium gigs with that without having to break out the JCM800. See if you can get your hands on one to try. not for everyone, but I sure love mine.
