number of customer requested feature and function upgrades. “We’re very excited about this limited release of the MF-104M,” said Moog Music CEO, Mike Adams. “Many of the parts we use to create these amazing delays are completely original and incredibly hard to find. Since this will be the last of its kind, we have gone to great lengths to incorporate features and functions requested by customers over the last 12 years. The MF-104M delivers those rich, creamy, classic delays Moog is renowned for, but also has the ability to modulate the delay time and create effects not found in any other analog delay." The MF-104M recreates the sound of the original MF-104. It uses 4 MN3008s, which provide 800ms of analog delay. A new 6 Waveshape LFO significantly expands the sonic capabilities of this Classic Analog Delay. The MF-104M incorporates Spillover Mode, the most popular modification to the Classic MF-104. A Tap Tempo switch lets users quickly tap in delay times or LFO rates, and MIDI capability allows control over every function. The rear panel contains ports for additional pedal inputs, to control other parameters. Following their August 2018 discontinuation, Moog Music have made limited reissues available of their MF-104M pedals from time to time as they gather and acquire batches of MN3008 chips. Moog Music did release yet another version of the MF-104 called the MF-104MSD which stood for Super Delay. These also had the same modulation features as the 104-M, including the same MIDI control, Tap Tempo, Spillover Mode but like the 104Z they were capable of producing delay times of 1200ms (1.2 seconds). Only 560 MF-104M Super Delays were produced and made available worldwide. An additional very small production run of about 30 units were built for the Gearfest trade show. These had the words 'Super Delay Small Batch' hand-written on the Black painted metal casing rather than the standard silk screened White paint. MF-105 Better known as the MuRF, the MF-105 or Multiple Resonance Filter Array is an original effects processor, designed by Bob Moog in 2004. The MuRF has 8 band-pass filters whose levels are controlled by 8 sliders which resemble a Graphic Equalizer. The filters' center frequencies are set at 200 Hz, 300 Hz, 450 Hz, 675 Hz, 1 kHz, 1.5 kHz, 2.2 kHz and 3.4 kHz and their sliders adjust the gain of each filter.
