2x Fx. He has some very interesting VCOs. Larry Hendry and anyone
else who attended AHMW2000 can attest to that.

I have done that before too just messing' around. You can get some nasty
distortion for other waveshapes though. I will certainly attest as Cary
said that Tony's VCOs were very interesting. They are not something for
sale, but ones that he made DIY for himself. He must of provided
waveshaping for all waves AFTER the fullwave rectifier as his VCOs had all
waveshapes out plus all waveshapes at 2X frequency. However, Tony is one of
those banana jacks guys. And, the crazy thing is his circuit boards were
all SMD (hand soldered). Now, very few of us have that kind of patience.
Tony is a talented guy. Next year at AHMW I just MUST spend some time
playing with his modular gear. Aside from his DIY stuff, he has one of
those Fenix semi-modulars and some interesting Modcan stuff. The Fenix is
kind of wild looking, but has stuff way too crammed into tiny spaces for my
personal taste. I guess they only made about 75 of those. The Modcan stuff
he had looked like nice quality, but the panels were all mixed with jacks
and controls. I am used to the non-cluttered MOTM approach to jacks and
controls on separate parts of the control panel. All-in-all, I thought it
was a very interesting set up.
Cary don't you still have some photos at your site?
