The MF-104M features an all-analog signal path with 800ms of all analog delay time, 6 Waveshape LFO, Dedicated Tap Tempo switch assignable to Delay Time or LFO Rate, MIDI control and recall of every function, and Spillover Mode which has been the most popular modification to the MF-104.
The Classic MF-104 was designed by synthesizer pioneer Bob Moog and released in 2000. It utilized a special "Bucket Brigade” delay chip that allowed the effect to remain completely analog. Unfortunately, the supply of these chips was limited and the final MF-104 was sold in 2001.In 2005 there were two limited reissues of the Classic MF-104; the MF-104Z and the extremely rare MF-104SD, of which only 250 were made.
The new MF-104M Analog Delay utilizes the same vintage Bucket Brigade chips found in the Classic MF-104 and faithfully recreates the sound of its coveted predecessors. In addition, the MF-104M includes a number of customer requested feature and function upgrades.
