A different flavor of flanger, for sure. It's in the BF-2 camp but to my ears, sounds like the odd harmonic setting on a A/DA flange. I still want to wrap my head around the depth and clock trimmers. There were lots of variation in sound available by playing with those. MB's flanger magic in the newest releases is here; this thing is dead quiet when you aren't playing. Very cool build. For the enclosure I used a white paint marker on a no-film decal to block out the skeleton. Super pleased with the results.
