I've had 2 in my time. A 5 string HH in Graphite Pearl (I think) and a 4HH in the same finish which I traded the 5HH for.
I liked the 5 tonally, and it was nice and light, but ergonomically the neck just didn't work for me at all... So I traded it with another Basschatter for his 4HH. Kept it for about a year and there was nothing much to complain about with it... I just fell out of love with it.
Having ticked the box now I don't think I'd own another, but there's no real reason for that other than I've ploughed that furrow already! That'll maybe change at some point, although given their current price, my love for all things ACG and all the other basses out there I've never tried, I doubt it!
Perfectly good basses. The look never bothered me personally. Sure it's a little different but so what?
