Everybody who knows gear can think of basses that companies should make but don't. Here is my list: 1. Stingrays/Sterlings fives w/19mm string spacing or at least 2. G&L JB-2 with five strings & 19mm string spacing 3. Fender Jazz V & Precision V with Sadowsky style neck profiles and string spacing 4. Passive Sadowskys 5. Fretless G&L Tributes and Ibanez ATKs.
