At 26:50 in this rig rundown with Premier Guitar, a Duophony Parallel Blender is seen on Rhett Shull's pedalboard. At 29:45 he says:
Another interesting pedal is the Duophony from GFI Systems. This pedal does not actually make sound. It's a stereo line mixer. So I have two pedals plugged into it, which is the Synesthesia from GFI and the Dark World from Chase Bliss, and throughout the show I'm using this to blend these two pedals together in different combinations and different sounds.
