Quote from: Ratbones on November 04, 2010, 11:58:40 PMHey deadastronaut, could I bother you to repost that colorsound wah breadboard layout again? I tried building it from the schematic and must have done something goofy... Thanks!
Quote from: Ratbones on November 08, 2010, 07:26:49 PMTurns out my goofy antivirus was blocking it for some reason. I breadboarded it following your layout but didn't have some of the necessary cap values. And... It didn't work. Dunno if it was my substituting, or the layout though. I did manage to get it working using the optochopto schematic though. It sounds really cool. Now I'm working on a triangle or saw wave lfo so it sounds more perty.

Quote from: deadastronaut on November 15, 2010, 12:09:06 PMhmmm strange, check the schematic on page 3...sounds like somethings wrong there..i take it you havent got a 555..so are using one side of a 556..should be ok, just double check the pin connections though!.
Quote from: tombola on November 15, 2010, 09:17:41 PMBeautiful design Deadastronaut, so simple. Love the way it's bidirectional - you don't need to label In and Out, because it doesn't matter which you use. Only problem I have is with quite noticeable ticking. I built it with two grounds - checked with the meter, there's no connection between battery ground and audio ground. Have a 100uf cap between +9v and (power) ground. I've tried it with two adaptors and a 9v battery, different guitars, different amps. It's there when depth is at zero - i.e. the LDR isn't bleeding anything to ground. Is there anything else I can try? Thanks!
