Verified Customer zZounds has verified that this reviewer made a purchase from us.
Just received my KO II last week with no fader or speaker problems. Diving into the work flow as I type this. To totally sum up my sentiments about this little machine, I am HIGHLY IMPRESSED and satisfied with the purchase. I can't believe the features this little machine offers for such a low price!! The only frustrating thing is the lack of a physical manual!!! Other than that, great job Teenage Engineering. The only request I have is some type of firmware update to allow connection of an external USB C storage device to allow users to archive projects and samples once the onboard 64mb is used up. I can't wrap up this review without tipping the fedora in appreciation to zZounds for the uber convenience of their Pay As You Play option making it possible for us to cop the gear we dream of with just a simple down payment and affordable monthly payments!!!!
