anyone see any artists using this stuff anymore

No I havent but I see some guys using the old stuff.......I think they got sold to GHS

Allan Holdsworth uses two Rocktron Intellifexes (silver faced version). I think he uses the multitap chorus effect.

Silver Face versions...where the special?????????

I am a huge fan of Rocktron stuff. great sounding gear designed by guitarists. I've met Jim Waller (old Rocktron owner)and Bill Blatter (co-designer), and they are nice guys. I have:

Power station
Replifex
Intellifex (black face)
Patchmate
300G compressor
Guitar Silencer
Rocktron/Egnater TOL 100 head
Rocktron /Egnater TOL 50 2x12 combo

and used to own:

Intellifex (silver face)
Pro Q
Hush IIC
Surf Tremolo
Tsunami chorus

so as you can see, I am a believer of their products!
