"These where designed and build by Jessica Rylan and are no longer in manufacture.
I am not a capitalist or a dealer, I just want these beauties to go to the right home.
I have loved using these and this is the second set I have owned, the first pair I stupidly sold, regretted it and tried to buy again, unfortunately they had stopped making them and it took me about a year and a half to track down another complete set.
The Little Boy Blue I bought from Allesandro Cortini (NIN), it has a few of the knob caps missing, 100% working, a few minor scratches to the paint underneath.
Jealous Heart I bought from a chap in Sweden, 100% working, a few little scratches underneath, the odd tiny paint chip.
These are designed to be used, last forever and built like a very well made thing. A lot of thought has gone into these, Rylan worked for Don Buchla and wanted to build something with as much sonic capability as a full blown modular, but could be slung in a bag for a gig.
Both units can process external audio from guitar, microphone, synth, drum machine or whatever else. They are sold as a pair (you will want both) and they work extremely well together, producing an extreme range of sound ideal for design, performance and sampling.
The price is fixed, I have them for sale elsewhere so the auction may end early and my price is very reasonable, the first set cost me loads more . Included is a set of 6 stackable pomona cables, I use a lot of banana gear and it is easy to make them up, you don’t need the expense of using pomona, you can get some really good stackable’s elsewhere you don’t have to solder.

"Unit is used and vintage. It is in good cosmetic condition w/ a little dust and such, as well as a few scratches and scuffs. It passed basic working testing. A cool older unit. John-Michel Jarre used this model back in the day.
