The Black BBD is one of kind analogues delay module - it features two BBD lines - short, 1024 stage, and long, 4096 stage, that work simultaneously, and you can smoothly fade between those two, thus creating distinct multitap effect. Furthermore, an advanced BBD clock noise cancellation circuit is implemented that reduces unwanted BBD noise without filtering higher frequencies of audio signal. Most of parameters are voltage controlled, which allows to integrate the module in complex modular setups.
