I think it's referred to here (the second bass described as a "severely modified" Ric):
Equipment
In 2007 Ed Roman built Dave a custom instrument designed with most of the same features and specs as the "Fendenbacker" (see below), with a Rickenbacker-like body shape but with a Fender scale length and neck width and more of a Fender body contouring.
Dave's main bass previous to the new Ed Roman bass is what he terms his "Fendenbacker". It's a Rickenbacker 4001 bass that's been severely modified to serve a variety of purposes. "A buddy of mine found a really trashed Ric in a pawn shop, and I turned it into a project bass to try to make a 'one bass fits all' for myself" says Meros.
It has a set of Fender Jazz Bass pickups set in mid-'70s-era spacing (the bridge pickup moved closer to the bridge than in previous incarnations, giving the bass a "tighter" and more midrange tone) as well as the standard set of Rickenbacker pickups in the traditional Ric positions. This gives Meros four pickups total to choose from, with a switch that chooses between the two fairly different "basses", Rickenbacker or Jazz. All four can also be activated at the same time. A BadAss bridge, Hipshot Bass Xtender (otherwise known as a "Hipshot D-Tuner" or simply a "Hipshot" or "D-Tuner" among bassists) for its ability to downtune the low E-string of a bass typically to D at the flip of a lever) and a string mute that Meros can raise or lower with thumb screws (which were fabricated by Meros himself) were also added.
