I don't have an SCF myself but have used and sometimes still use the (rackmount) TC 1210 - Spatial Expander with my Boogies: http://www.tcelectronic.com/TC1210. Apparently both effects can yield similar sounds? From TC's website:
"Utilizing the technology of TC’s world famous Stereo Chorus/Flanger Pedal, the TC 1210 has additional cross-coupled audio and independent clock circuits that produce dramatic enhancement of the stereo image".
In my opinion TC Electronic effects sound best in a stereo setup. I usually put the TC 1210 (or my Yamaha UD Stomp) between my preamp (mono out) into my stereo poweramps (20/20 or Simul 295).
