UPDATE: I noticed the Japanese site has removed all of the exhibition models! So I've added all of the photos I have of these basses...I came across some very unusual Aria SB-1000's on Aria's Japanese site. They are apparently exhibition models and it doesn't seem like they will be produced on a large scale. However, it does look like they are for sale since they have prices listed (around 180,000 Yen!) on the site along with the specs! They're definitely some of the most unique SBs I've ever come across! There's even a model with a Kahler Tremolo! I'm kind of partial to the black 5 string with orange stripes!
Here are some pics, but be sure to follow the link to Aria's site for even more photos!
