Type "Bass" in the description box, but select guitar from the dropdown menu. As of today, there are 11 pages of mis-categorized bass guitars, which a person may otherwise overlook if they only choose bass from the dropdown menu.
Sure, many are around the Squier/Fender MIM/MIJ, Ibanez, etc range. However, within that 11 pages, I've looked quickly and probably missed a few good ones, but here are some interesting basses which are presenly hidden due to their mis-classification...
