MF-104M Analog Delay

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.

The MF-104M will be available for a limited time, so grab this piece of Analog history before it’s gone forever-forever-forever-forever!

 

Front Panel Features:

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 40ms – 800ms of analog delay time

SHORT/LONG RANGE: Select between a short, bright delay 40ms to 400ms and a long, dark delay 80ms to 800ms

FEEDBACK: Continuous control of Delay line output fed back to Delay input from no Feedback to infinite.

WAVESHAPE: Selectable 6 Waveshape 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. 

 

LEDs and Switches

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. 

 

REAR PANEL Features:

AUDIO IN: 1/4” TS jack that accepts any instrument level to line level audio signal.

MIX OUT: 1/4” TS jack with adjustable output level for instrument or line level output.

DELAY OUT: 1/4” TS jack that supplies wet-only output.

FEEDBACK, TIME, LFO RATE, MIX, LFO AMOUNT: All are 1/4” TRS jacks that accept Moog EP-2 (or equivalent) expression pedals, or 0-5VDC control voltages from either two-circuit (TS) or three-circuit (TRS) 1/4” jacks.

FEEDBACK INSERT: 1/4” TRS jack for inserting effects on the feedback loop of the Delay Line. Supplies line-level output.

MIDI IN: 5 Pin DIN input for controlling the MF-104M via MIDI.

+9VDC POWER JACK: Accepts standard 9 volt center positive barrel power adaptor (power adaptor included). 400mA minimum required.

 

General Specifications

CASE: Black panel with hardwood sides - classic analog appearance.

DIMENSIONS: 9" x 6" x 2-1/2"

NET WEIGHT: 3 lb

SHIPPING WEIGHT: 5 lb, including power adaptor and instruction manual.

POWER REQUIREMENTS: 105-125AC, 5W. 220AC 50Hz either European or UK style power adaptor available on special order.
