I have one from 2002. I never got a good sound for humbuckers with it, but it got along okay with my Strat. It sits in a box now, ultimately, a disappointment. YMMV.
I just bumped the last Fulltone thread Fulltone Pedals and Mike Fuller's Collection.
Also, use the search function for Fulltone, and it'll bring up a lot of good info.
