Mentioned in the July 31, 1982 issue of Circus.

"The most exciting thing that's happened to me in a while is the invention of the Gillis Wireless Switcher. I was talking to (inventor) Greg Gillis. saying it would be great it there was a switching system the size of a deck of cards that you could attach to your guitar strap—something with a calculator keypad that would transmit to all the switches on your rack. That way you would never have to have any foot pedals on stage. A week later he called me up and said. 'Come and get it.' I hit the ceiling. It was a dream come true. He took a nebulous idea of mine and I saw it realized in a week! It looks like a badge on my guitar strap with an antenna coming out of it. I have eight switches in there and a master clear button. Among Ronnie's effects are a modified Moog string filter. a Moog Phaser. two Lexicon PCM 41's. a Dyna-Mite Limiter Gauge and a Vocoder.

"The Moog String Filter resulted from Moog taking an orchestra and analyzing the waves of the string section. They built this into separate filters. The idea was good. but they never completed the design. It was very noisy and didn't resonate properly. You couldn't control the range of the filter. I tore it apart. put in DBX cards to quiet it down. and used a blend pot on the ranges rather than on off switches. I'm now able to dial in a very sweet tone.

"I'll always continue to experiment with new things. But after all is said and done, the fail-safe I utilize is my talent as a guitar player. When all else fails. I plug directly into the amp and do what I do best, which is play the guitar. Everything else is embellishment."
