| Well, I probably should respond to this, although I have little gig experience with this bass. First, it is perhaps significant that Tim Landers has one of the first series of lightwaves, and I am not sure at all whether there is a significant difference between this and the current series II.
I have a series II, one of the Ohio LightWaves, maple board fretless. Apparently, it is one of the good ones, because it has been reliable for 5+ years. It came with steel strings of some kind, I have heard they might be SR2000s. I did not like them at all. I put on Acousticores right away, and love them. They are very lively strings, with lots of upright-sounding bloom to the notes, and the lightwave system gives them lots of low end. But, they do not thump and die like an upright. You have to pluck them very hard, turn the volume down, and use the side of your plucking finger knuckle to get them to respond in that way, but you can fake it. Played like a normal fretless bass guitar, they sound wonderful, but not really like an upright.
My E string broke recently, and I was desperate for a temporary replacement while I waited for an Acousticore E replacement. I tried the original steel E (even worse than I remembered), another spare roundwound, and a Labella tapewound E. This just did not work. I finally put on a Labella 760N A string and tuned it down to E, and it matched the Acousticores in tension, output, and general sound pretty well. It sounded like plastic compared to the sophisticated sound of the Acousticores, but it worked.
Well, I don't know if this is helpful. I do have another fretted bass with TI Jazz Flats, and I think they might really work on the Lightwave, but I have not tried them. lbanks has, but I am not sure he is still around to ask. |
