Has somebody messed with your Axcelerator ?
The RSB pairs VFL pickups with passive Vol, Blend, Tone.
Axcelerators shipped with VFLs and a High/Low Boost/Cut preamp.
Other way 'round, I think. But yeah, the RSB is missing the stacked treble/bass knob, so that is different. I am not sure it's stock though, because the electronics look too new. I also don't think it sounds quite right, so I'll have to investigate. I didn't think to consider the preamp could be passive with active pickups, but it seems to be the case since it just has a "tone" knob. Peavey is so weird ;-)
At any rate, I would say they were made about the same time because they have the same bridge, tuners, neck construction/finish, angled headstock, so feel really similar. 'Course, there is the funky headstock. At any rate, it is a really sharp looking bass. Oh, I think the neck radius is larger, since it seems flat like my fretless axcell.
