This seller always seems to have rare items in excellent condition. Is this mainly because it's in Japan? Don't know if the market's the same over there and if the original distribution of products was equal to what was exported elsewhere?
I have a hard time envisioning how someone is going to get the "jet plane" sound without the noise... this sound essentially is the inherent noise in an analog-BBD flanger -- and also why the Electric Mistress is such a wonderful sounding piece of junk.
Probably going to sound more like a PH-1r or PH-2 with some resonance kicked in.
