Unlike most ribbon motors designed today with an offset ribbon the new Cascade FAT HEAD houses a hand-tuned ribbon element that incorporates the legendary symmetrical ribbon design. This design offers a true figure 8 pattern. The corrugated aluminum membrane itself is positioned in the center from front to back, thus producing a balanced audio input signal to both sides of the ribbon assembly. This design is very useful when executing a mid-side or Blumlein recording set-up and also great for live stage use. The FAT HEAD warm full-bodied signature and increased sensitivity is what you would expect and demand from a professional ribbon microphone and the FAT HEAD delivers. The FAT HEAD is suited for guitar cabinets, drum over-heads, vocal, piano, horns, strings, and much more.
