The MF-104S Analog Delay is a reinvention of Moog Music’s classic MF-104 analog effect pedal.
The MF-104 Analog Delay, introduced in 2000, added a lush, all-analog delay to the classic line of Moogerfooger effects. It included a Bucket Brigade Device (BBD) with a range of 40 milliseconds to 800 milliseconds. Later versions of the MF-104 offered tempo synchronization and extensive time modulation capabilities via a multi-waveform LFO. Designed by Bob Moog and his engineering team, the MF-104 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate and play inputs from guitar, voice and synthesizer to every imaginable audio source.
The MF-104 Analog Delay has been meticulously reconstructed as the MF-104S, retaining the warm, organic texture and character of the original analog delay circuits, and adding 21st-century flexibility and ease of use.
With CV interconnectivity, stereo functionality, an expanded feature set, the ability to run multiple instances and presets, the MF-104S plug-in further adapts classic Moogerfooger functionality to the modern digital maker.
