i've been muckin' around with cubba's, and i must say, this is a great optical-style compressor (ala menatone jac, which i LOVE!)! it's greatest asset, though, is the tone pot. placed after the comp (where it SHOULD be!) in it's signal path, it adds a very even-handed upper freq'cy content that makes it perfect getting that glassy sound that kills with a bit of chorus & delay after it. it's not a squish-style comp; it won't provide that much compression. but it's great when used for a clean sound or a boost for other drives. the clips at the diamond site do NOT do this box justice, let me tell you straight up. it's a very live sounding comp with an eq that WORKS! like a champ! i am very impressed.
