Rocket BB help

[Colonel Angus]

Hello. I know there is a litany of info about this build, I have searched it to the limit of my patience and only found suggestions/fixes in the vague realm of what I'm experiencing.

Built a rocket from Aron's schemo : http://www.diystompboxes.com/pedals/rocket.JPG

Schemo works on breadboard, super bombed out fuzz! Problem is the noise. Now I expect a fuzz of this intensity to have some noise, but on breadboard the noise is as loud as the signal. Granted the monitoring setup at my bench is less than ideal and fairly noisy in general, this is unique because the led metering on my mixer literally jumps to the same level - playing or not. Turning the guitar volume down quiets things up but that is all I got. I've tried adding some diodes for current protection and a cap for current filtering, but to no effect.

Sorry i don't have more info to diagnose the issue... I'm looking for some general advice to get to the bottom of where this CRAZY level of noise is coming from.

Thanks in advance!

Hello!

First question: does the noise occur when you hook your rocket (   ) to a battery instead a wallwart, too?

Is your circuit still on the breadboard? If you put it in a metal enclosure it will probably reduce the noise to a more manageable level. The enclosure will shield the circuit from many unwanted interference that can produce noise.

@ pharod : no wallwart, only 9v batteries. My guitar player friends have re-appropriated my 9v dc wall warts 

@ vince_b : still on BB, but the noise level is waaaaaaay beyond the interference of anything else I've built. I agree with you that the lack of shielding is definitely adding some noise, but this is really intense. Again, with the guitar volume up, the VU on my mixer jumps as high whether I'm playing or have the strings muted. This leads me to think that there is something in addition to the absence of shielding. This is just speculation though, my theory is shaky at best with more of an emphasis on trial and error.

Thanks for the response!
