Signal Delay Unit Model 277 by Black Corporation & Buchla
The reissue of the Model 277 is a deceptively simple design that offers a wide range of time-based effects, from extreme cross-modulation to subtle, tape-like warble. It’s based on a fully analog BBD circuit.
Features:
• A, B, and C inputs with overload indicator
• 3-channel mixing and input attenuation
• Delay time, ranging from 50 - 200 ms
• Separate delayed signal outs to output specific taps - at ¼, ½, ¾, and full delay time
• Modulation input with attenuation (audio signal)
• Delay time control input with bipolar attenuation
