In 2000, Bob Moog designed the MF-104 Analog Delay and discontinued it in 2001, but in 2012 Moog introduced the Moogerfooger MF-104M Analog Delay for mass production. The MF-104M includes the same bucket-brigade delay chips found on the original for up to 800ms of delay time, but has additional features such as Spillover mode, Tap Tempo, a 6 wave-shape LFO, and MIDI In. The MF-104M is considered to be one of best and most fully-featured analog delay pedals out there.
