I picked up an OCD (4/18/2005 date inside) from by brother in law.. I play thru a MazJr 2x10 and '76 SFPR and '76 SFSR and it sounded OK but a little brittle on top. Basically, nothing special. I use the Gain on 0 or 1/4 to just drive the front end. I decided to check the battery and it was low so I replaced it. MAN.... talk about a new pedal!!! Its just what I like. The tonal reproduction (especially the bottom) on these little suckers (compared to the compressed TS808) is UNREAL. Now the top is sweet. It's got just the right amount of grit so it still sounds like I'm playing thru a Tube amp and not a tube amp connected to a solid state pedal. I might try a 12V supply just to see. BOTTOM LINE, check your batteries in your pedal. :RoCkIn
