here's a thread at kvraudioDr. Fluffenstein wrote:How does the rob papen delay compare to the free alternatives out there in terms of sound character? I'm not so much interested in the routing possibilities as I am in the tone it has. Is it anywhere near as good as echoboy? Would it still be worth buying if I just wanna use it as a basic stereo delay?
