So is this near impossible to get? why would they make this limited edition, and continue to issue black/blue lite AE voyagers!!! seems wrong. From what I’ve heard NAMM 05 may see 106 delay-hybrid…? 
They only made a limited number of 104s because its design incorperates a now out-of production semiconductor analog delay circuit called the bucket brigade chip. Apparently Moog Music somehow got a hold of some of these chip to make the 104, but they only had like 1000 of them. No more bucket brigade chips means no more mf-104.
