I've wondered about an onboard preamp for a bass with a chip that uses bass modeling (like how so many companies are making bass amps and pedals with amp modeling). Have a rotary switch that will cycle through different bass sounds. That way you have the Spector 9v, 18v, Tone Pump, Aggie OBP, EMG BQC, all right there in one bass. Even add modeling for Ricks, Walls, Sadowsky, etc..
If done well that would be really cool I think.
Line 6 had the Variax Bass that modeled a couple different basses (ric, t-bird, p-bass, stingray....) it could prob be done with the above mentioned...although the Variax is not a very nice looking bass tho, IMO
