Behringer – 172-Phase Shifter, Delay, LFO – Notes
The Behringer 172 is a faithful analog recreation of the Roland System 100M 172 module from the early 1980s. This versatile 16 HP multitool combines a 6-stage phase shifter, bucket-brigade device (BBD) analog delay, a dedicated LFO with triangle/inverted outputs, and a gate delay section for pulse shaping—all in one compact package. Internal routing lets […]
