I'm in the process of purchasing, probably in the coming week. But I find red just like the basses shape plain ugly! (don't mean to offend anyone).
I had wished they created this bass like the MKII, more like a steinberger, a simple square stick with minimalistic looks, but I'm not willing to pay $1500 for a bass like that!
So I'm stuck with black and blue.
Black in my mind is so common, and I prefer the purplish blue compared to the original guild blue.
I think the blue is not too RED-IN-YOUR-FACE, and neither is it 'YOU-HAD-A-BLACK-ASHBORY?I-DIDN'T-NOTICE'-like.
Black definitely looks best, but is so common, and people won't notice the bass.
Therefor I'm looking into blue.
Like mentioned somewhere else, you could always paint it in whatever color you like!
