The verdict is in on the comparisons. For all of their similarities, the differences between the 2 are definitely noticieable. For those new to this thread, this is a similar copy to my other Warmoth J-Bass. Other than the finish, the 2 are identical except for the neck woods, fretboard woods, and fret sizes. Same harware, pickups, bridge, controls, and layout.
Neck Dive:
On the Orange one, it is slightly neck heavier compared to the T-Burst one, but hardly has neck dive issues. When I weighed both, they were both 9.5 lbs. However, this was hardly scientific as I used a bathroom scale with me and each one and subtracted my weight to get each bass's weight. It's a digital scale and it's increments are in half pounds, and I do not know what it's rounding criteria is. It may have rounded one up and the other down to the nearest 1/2 pound because the Orange, Wenge necked one feels heavier. Also, this assumes that the bodies are the same weight. The T-Burst one may have a heavier body and the Orange one a lighter body which the neck differences compensate for with the total weight. There could be atleast a 1/2 pound difference in the completed builds and the scale wouldn't recognize this. A 1/2 pound isn't much, but if it only weighs 9.5 pounds, that's more than 5% difference.
Feel:
No doubt the Wenge feels better to the touch, and at first seemed too slick. The Maple (with finish) still feels fine, and only when compared to the Wenge would it feel strange. It's much like an HD TV ruining your enjoyment of a non-HD screen, or even comparing a Warmoth to a non-Warmoth. Ignorance is bliss. Both are the Standard thin contour but the Wenge feels thicker than the Maple. I haven't taken measurements though as I have no way to do so. I can not feel any discernable difference between the 6130 and 6150 with bass strings. I have the action set as low as I could on both and am using the same brand and gauge strings. I have a medium touch, and neither necks allow the strings to touch the fretboards.
Sound:
Neither one is better or worse but they are definitely different. Maple is supposed to be brighter, and is as far as I can tell, but the lows out of my amp sound fuller on the Maple one. The Wenge one is right at home in the midrange.
