Azumi's pop up here in Oz from time to time.
I have followed them with interest for a while.
The main reason that they interest me, is that they seem to share elecrtonics & hardware with the early low end Wing series Washburns, Ravens etc.
A friend of mine had an Azumi that in every way, bar the body shape was exactly the same as a series 2 Raven that I had.
Same pots, same wiring, same switch, same bridge, same nut, same neck profile, same pre logo tuners as the washy, even exactly the same color.
General Consensus from folks I have spoken to is they were a house brand for Chushin Gakki.
Most Azumi's also seem to be copys of other Japanese Brand Guitars.
Here is a link to an Azumi Bass thats for sale on Evilbay Aus, Look Familiar.
