Lightwave saber. picked it up recently , it's awesome, the lightwave system on the fretless is what everyone says, "perfect!."The bass is now set up E-C with a new set of Labella black tape wounds. High C sounds sweet! I'll shoot some new pics with the current set up. Bass is in mint condition, new battery, power supply, manual and tools included. Ash body and rosewood fingerboard. buyer pays shipping charges. going back to 4 strings only so this one is up to help finance a 4 string fretless.
