I had a new rockbass double buck the tone wasn't as aggressive as I had hoped & it wasn't very versatile , I like the bare bones rockbass corvette passive ,it has that traditional Warwick growl and fits better in the mix IMO,I also have the mb2x12 and it will really handle the b no problem,I also feel that the basic has a better b string , I think this is due to less magnetic field produced by the thinner well spaced pickups,they should have put more switching options on the $$ just series /parallel so you either get mudd or thin
