I have the OCD and love it. But I use it on top of my gain channel and am still in the market for an OD for my clean channel. I tried the Sparkle drive the other day and It is unique. It is a different animal than the normal tube screamer or fuzz and you can get some interesting sounds. It didn't fit my specific need but it was very cool and I almost bought it used anyway. Definitely try it if you can get your hands on one. PS.. I found it a little noisy though.Cletus said:So shoot some names at me to think about. I like the Voodoo Labs Sparkle Drive thus far.
