Moog Analog Delay MF-104z

YouTube via ProGuitarShopDemos.
"The MF-104Z soundz fantastic and like all Moogerfoogers it has controls that allow you to vary the sound in a variety of ways that you can only do with a Moogerfooger.
Controls include:

Drive and Output Levels
allow you to set-up the Z to match the type of signal you want to delay from low level signals (vocals,guitar) to strong signals (studio console output, drum machine). The Z is designed to work with them all.


Delay time: from slightly less than 50 msec to slightly more than 1000 msec.

Mix: Pot Control from completely Dry to completely Wet or anything in between.

Feedback Control
mixes a portion of the delayed signal with the signal from your instrument. Feedback control can generate a single echo, sustaining echoes, or echoes that build up in chaotic ways.

Switchable Internal Loop / External Loop
selects the feedback path. In the Internal Loop position the feedback path goes directly from the output of the delay back to the input. In the External Loop position the feedback path goes through the Loop Out Jack and the Loop In Jack. This gives you an opportunity to insert signal processing in the feedback path, thereby enabling processing of the echoes as they are generated. Very cool with another Moogerfooger (unbelievable with the MuRF)."
