Pittsburgh Modular has released this official intro video to their Analog Delay module:
The Pittsburgh Modular Analog Delay is “a brand new analog delay module designed around a pair of 4096 Bucket Brigade Delay Line (BBD) ICs to produce a distinct analog delay effect. The maximum delay time when shipped is set at 9/10ths of a second but this can be adjusted up to 2 seconds.
The Analog Delay offers voltage control of the delay time, feedback, and wet signal. A true bypass switch allows the delay to be enabled and disabled quickly.”
See the Pittsburgh Modular site for details.
