Moog MF-104M Super Delay - Limited Edition

The Moog MF-104M Super Delay features over 1.2 seconds of vintage, analog delay time provided by 6 NOS Panasonic Bucket Brigade chips. The power supply, bias, and rail generating circuitry have all been improved for greater sound quality and reduced microphonics, and an Emphasis/De-Emphasis circuit has been added for reduced noise. Additionally, the delay-loop level matching circuitry from the 500 Series analog delay has been included for maximized feedback and mix stability.

The MF-104M Super Delay includes all of the features found in the MF-104M analog delay, including MIDI control of every feature on and under the hood, a 6 Waveshape LFO, tap tempo of delay time and LFO rate, spillover mode, and the traditional short/long delay switch for bright, articulate 50ms-600ms trails, and dark, mysterious 100ms-1200ms trails.

Like all Moogerfoogers, the MF-104M Super Delay is housed in a rugged steel chassis with wood sides and utilizes CV/Expression inputs for external control of Time, Rate, Feedback, Amount, and Mix parameters. A delay feedback Insert is also available for adding external effects to the delay line.

• Dimensions: 9" x 6" x 2-1/2"
• Weight: 3 lbs
• Power Requirements: 105-125AC, 5W

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 60ms – 1200ms of analog delay time
• Short/Long Range: Select between a short, bright delay 50ms to 600ms and a long, dark delay 100ms to 1200ms
• 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):
  • Red when the Rate is set from the front panel
  • Green when set by Tap Tempo
  • Orange when the LFO is synced to MIDI clock
• 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

*Note: When synced to MIDI clock, the Rate control is quantized to select only rhythmic subdivisions of the MIDI clock tempo

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-3 (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

“In 2005, we released the MF-104SD, of which only 250 units were ever produced. The new MF-104M Super Delay utilizes the identical vintage Bucket Brigade chips found in the classic MF-104SD, faithfully delivering a vintage grittiness that's extremely musical.“
