Hi.

I built a Bazz fuzz that is actually 2 bazz fuzz's in series. On the output iam gettng a VERY strong radio station signal. easily as loud as the actual guitar output.

Interestingly enough there is NO radio signal interferance at the output of the first bazz fuss. only when both are together in series. Is there any way to get rid of this or lessen it.

Im using 5088 transistors an 4148 diodes. Any help is appreciated.

thanks

radio shack has 7 entries in the ferrite bead section [i went to RS online and typed in 'ferrite beads'].
 If I could figure out which one to try, we could achieve RF rejection.

Have you already installed it in a grounded, metal enclosure?

That takes care of RF interference 95% of the time.

yes. grounded and enclosed in RACO

I guess any  ferrite beads will work?

Update

Managed to get rid of most of it by adding a capacitor to ground inbetween stages. Actually i used a cap value that still allowed some of it through lek a random high pitched squeel. No stations come through just some squeely static so it sounds kinda cool with the fuzz.
