Folks, I got lucky and had some extra time. I was able to finish the complete kit. There's still some detailing I have to do (for example grommets), but the complete thing is up for a test run now.
Been playing it a band rehearsal. It is really present and cuts through the mix nicely. The toms are loud enough en sound very clear. The bass is a firm kick in the ass, but has a lot of musical tone. I haven't tuned it to perfection, but it allready sounds really good.
After some time, when all the detailing is done, I'll post some higher quality daylight pictures.
