Based on the sound of the regular M117R FLANGER, the M152 MICRO FLANGER is designed to deliver a classic yet versatile flanging effect in a smaller enclosure. Just like when it was first released in the 80s, it has two control knobs: the RATE knob adjusts the rate speed of the effect, and the REGEN knob adjusts the intensity of the effect. Furthermore, the adoption of BBD technology delivers a warm and lively tone, and it features true bypass. From jet sounds to spacey sounds, this single unit lets you do whatever you want. specification: Input impedance 1MΩ Output impedance 1kΩ Maximum input level (@500Hz) -2dBV Maximum output level +8dBV Rate control: Min/Max 0.2Hz/5.5Hz S/N ratio >88dBV Delay time: Min/Max 3.9μs/4ms Frequency response effect ON: 20Hz to 10.7kHz Bypass 20Hz–20kHz Current
