GT SONIC's compact ultrasonic cleaner for commercial use. It's not for audio only, but it seems that it can be used for quite a variety of purposes. I think the size is good too. If you've been looking for one, take this opportunity. You can see the exterior, dullness, and feeling of use (Kobayashi Hitoshi)
