Can't decide if I will actually post a video because my mind was more on the disparity of tone coming from my duo-string setup last night.
The ThunderGuts are great, at least the D and G. Acoustically, they are tighter and brighter. One poster says, you can EQ that even. True to a point. The white strings are missing that undertone, or subharmonic part of the note. The black strings are great at that. Not this extreme, but it's like playing lower notes on an upright and upper notes through a high pass filter set at 80hz on a Jaco jazz fretless. More definition, sustain. Not "mwah" Pre se, but definitely more mids put out from the string sustaining against the wood. They are loud and have more singing quality up high than the blacks, but are missing that thump. I can see totally using these if my U-Bass were being used in place of an electric bass, as many on here are. The white strings would be perfect. But I am using it primarily instead of my upright. And on last night's gig specifically, instead of both. But I tend to prefer that open, airy, thumpy upright sound with low sub harmonics filling in the attacks "under" the notes. Does that make sense?
about the Ray.
Yeah, I have a fretted Ray 5. I'm getting a Ray 4 fretless. So not exactly the same, but I was really hoping to use it a little last night. It is insured. I'd rather have the bass, though.
