Decided to pull the trigger on a stingray style bass, and I'm so glad I went for the Z3. The 3 band EQ powered by 18V gives you loads of tone shaping options, and the push/pull bypass gives me peace of mind that I'll never be caught short during a gig (the bass sounds great in passive too, but I always use it in active). I'd say the general tone is quite clean and modern, a bit less 'woody' than the Sterling basses I've heard. Perfect for me.
The neck isn't exactly narrow, but I wouldn't say it was uncomfortably wide either, it is quite 'shallow' so not at all like a baseball bat! In combination with the rolled fretboard edges it's a very very comfortable neck to play.
I've heard some negative things online about the quality of tuners on the bass, but to me they are absolutely fine, and I won't be replacing them. The lower horn is short, but I've not had any issues with that - it's never slipped off my leg while playing.
My only issue is that the bass arrived with quite a bit of fret sprout and some dings on the fretboard, this is why I can't give a perfect score for quality. Thomann quickly rectified the issue, and the one they re-sent is an absolute dream. It's light, feels good, looks good, and sounds good. If you're in the market for a stingray style bass I would absolutely recommend this. Honestly if someone told me this bass was twice the price it actually is I would have belived them.
