Originally designed by Bob Moog and released in 2000, the Classic MF-104 Analog Delay was manufactured as a limited edition release of 1000 units.
A special "Bucket Brigade” delay chip was employed allowing the effect to remain completely analog. Unfortunately, the supply of these chips was limited and the final MF-104 sold in 2001. Since then there have been two reissues of the Classic MF-104, the MF-104Z and the MF-104SD. In that time, each has been added to a short list of the most sought-after analog delays in history. The MF-104M recreates the sound and vibe of the Classic MF-104. It even uses the same vintage “Bucket Brigade” delay chips found in the original, which provide 800ms of the richest, creamiest, all analog delay on the planet.
A new 6 Waveshape LFO significantly expands the sonic capabilities of this Classic Analog Delay. Use it to create expansive delays that transport you through time, beautifully modulate the delay trails, or create sounds and delays that are simply out of this world.
Spillover Mode has been the most popular modification to the MF-104 and is now included in the MF-104M. Decide on the fly whether delay trails end or continue when you disengage the Delay.
A dedicated Tap Tempo switch lets you quickly tap in your Delay Time or LFO Rate, and the addition of MIDI brings a new world of control and function to the MF-104M. Use it to control and manipulate every function on and under the hood. It’s also a great way to incorporate an analog delay into your studio productions.
Rear panel features include CV/Expression Pedal inputs which provide hands-free control and manipulation of Time, Rate, Feedback, Amount, and Mix. Like all Moogerfoogers, you can connect Moog EP2 expression pedals to any of these CV/Expression inputs to control functions, or connect other Moogerfoogers and create new effects. Additionally, the Feedback Insert allows you to patch in other stomp box or outboard effects onto the delay line for even more creative flexibility.
Drive: From -7dB to +28dB of input signal gain or attenuation
Output Level: Use to optimize overall Output volume
Mix: Cross fader control to set the ratio of wet to dry signal
Time: Control range of 40 ms - 800 ms of analog delay time
Short/Long Range: Select between a short, bright delay 40 ms to 400 ms and a long, dark delay 80 ms to 800 ms
Feedback: Continuous control of Delay line output fed back to Delay input from no Feedback to infinite.
Waveshape: Selectable 6 waveshapes LFO for modulating the Delay Time
Rate: Controls the LFO Rate from 0.05 Hz to 50 Hz (Wider range available via CV and MIDI)
Amount: Controls the overall Amount of LFO modulation of the Delay Time
Time LED: The LED is red when controlled by the Time knob, and Green when controlled by Tap Tempo
Level LED: Bi-Color LED displays input signal for optimum processing level
Bypass LED: When the effect is on the Bypass LED is green. When in Spillover mode the Bypass LED is orange. When the effect is off the Bypass LED is red
Rate LED: Indicates both the Rate and Waveform LFO settings. The LED is red when the Rate is set from the front panel, green when set by Tap Tempo, and orange when the LFO is synced to MIDI clock. Note: When synced to MIDI clock, the Rate control is quantized to select only rhythmic subdivisions of the MIDI clock tempo
Tap Tempo: Tap Tempo control assignable to Delay Time or LFO Rate by holding down the switch. Time LED or Rate LED will flash Green to indicate Tap Tempo assignment
Spillover Mode: Press and hold Bypass to engage/disengage Spillover Mode
Audio In: 1/4" (6.3 mm) TS jack that accepts any instrument-level to line-level audio signal
Mix Out: 1/4" (6.3 mm) TS jack with adjustable output level for instrument- or line-level output
Delay Out: 1/4" (6.3 mm) TS jack that supplies wet-only output Feedback, Time, LFO Rate, Mix, LFO Amount: 1/4" (6.3 mm) TRS jacks that accept Moog EP-2 (or equivalent) expression pedals, or 0-5 VDC control voltages from either two-circuit (TS) or three-circuit (TRS) 1/4" (6.3 mm) jacks.
Feedback Insert: 1/4" (6.3 mm) TRS jack for inserting effects on the feedback loop of the Delay Line. Supplies line-level output
