it falls short when recording
an overpriced time suck of a paperweight
Considering the cost of parts, the lack of support, the absence of an accurate drill template (which was a challenge to figure out), and the overall complexity of the build, I’d go so far as to say that the only meaningful difference between this and a $60 Mackie 4-channel mixer is the sends bus — and even that is "meh" at best.
If I had bought the Klein Bottle at retail price, I’d be pissed.
Anyone who claims to love it is either lying or justifying their investment of time and money.
