Bass is a Rob Allen. It uses a piezo under the bridge. I have a new Deep 5 model on order with him, but happened on this MB-2 used. I'll likely sell it when the new Deep 5 shows up. Big, fat organic tone. Will pass as an upright in a busy mix and is just flat out fun and involving to play.
The new Deep 5 will look like this, but mine has a rare blonde walnut top
