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.
