Funny someone should bring that up. In a local Burger King, the owner did the whole interior in a retro '50's theme and.....get this.....he lagg boilted a Bond to the wall. Not very '50's and not very wise.
Does anyone remember the fretless wizard in BP in the early '90's ?
How about the 1/4" instrument cables with some wierd milky liquid in them (encased in a plastic shell). I still never knew what that was all about.
Lane Poor's ferrite beads.
Tony Levin's Funk Fingers.
The Washburn Wonder Bar.
Rockinger Bass Tremolo.
Some where out there is a bass with actual preamp tubes in it.
Raven Labs. I thought they would last longer.
Optical pickups.
Headless basses never really caught on.
Armour Cables.....I haven't seen them in a long time. They won't honor my warranties either.
PentaSystems basses ??????
Starr Labs on board electronic pickup switching.
Axon controllers.
Rockman Amps.
The Double Whammy.
EBows.....I know they're still around but IMHO are a failure.
Zolla's 425 and 426 necks.
And let's not forget the G&L 8 String Bass Initiative. That site's been on Harmony Central for over 10 years and it never came on line.
Headless basses still sell actually. I'm sure Steinberger, Status and Hohner would have given up a long time ago if not.
