If it's really volume, tone, volume, tone then not Epic electronics. Of course if it's only been played four hours in the past 11 years, then maybe the owner is mistaken as to the controls. If there is a build sheet, that would say.
Since everything else is unusual on this bass, it could be that the electronics are a modified form of Persuader electronics, with a volume and filter for each pickup; if it is indeed volume tone volume tone. On the other hand, it may just be Epic electronics.
I too was thinking that perhaps it's a set neck, but it's hard to tell. The truss rod cover tends to suggest that it's a neck through.
The lack of a logo, along with all of the other unusual features, should prompt any prospective buyers to ask for the serial number and a copy of the build record. The seller states that it was purchased as an investment, so it may be that the build record is still in the case along with the tools.
