The Freebrid is a 3 Channel valve EQ, company director Nick Terry explains, "We've introduced a new product that can be considered as part of a modular system, in our own unique style of course. The Freebird has 3 channels of broad but versatile valve EQ. The unit is a half rack design but can be put together in a 19 inch rack case with another unit to give 6 channels of EQ."
