"Broke after 4 hours no support from Waldorf"
Overall: 0.5 out of 5 stars
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Wanted to love this synth. Had it 4 hours when the screen started going out, then the Osc 1 particle button stopped working, and the other buttons worked sometimes. Tried to get ahold of Waldorf but they never responded to emails or messages so had to return it. Now we are having to wait for our replacement which no one knows when that will be because Waldorf is not delivering units AT ALL now. So after dropping almost $3k on a synth no one has any idea when we will get our synth, but hey we got a gift certificate for $100 off my next purchase. Because you know that equates to the nonexistent almost $3k synth we paid for.
