Strange request for fuzz, how to increase radio interfenece?

I know most people try to make their pedals a quiet as possible. I would like to build an uber trashy sounding fuzz. I thought it would be fun to have lots of radio interference coming through. How could I increase it? I saw this pic from beavis audio and it gave me the idea.

Put an antenna at the input in parallel/series with your guitar signal, or, anywhere in the circuit!. Something like this UFO DETECTOR!

Cool thanks! I may make the antenna switchable to turn it on and off, or use a pot to dial in the amount of interference

interesting idea...though i don't seem to need one of those as i seem to attract ufo's already......had some very strange experiences.

one of which was really up close....  sorry to go OT....as you were... ;)


@ghost: add a tiny  radio into your pedal...can be bought in poundshops etc...just move the vol/tune knobs onto the box..and mix them.

that antenna appears to be grounded?!? will that not ground any radio/interference ?
i've had good results by hanging a long piece of insulated wire from the input of fuzzes. one end connected before the input cap, the other end not connected to anything.

I would just hide a radio underneath the pedalboard and couple the audio in with a wire.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

my "best results" were achieved by building a 741 into clipping diodes pedal, with no regard for upper frequency limits, ie good practice. with the right length of guitar lead at the input, and output, we were getting 'radio russia' and others, w/ plenny nice shortwave swoosh and phase/fade, all that good stuff, and could be tuned just by moving around.

never got it to go good again, though.

This crystal radio might also work: http://www.techlib.com/electronics/crystal.html

using a germanium diode and couple it to your fuzz.

Cheers.

P.S. (edit)
I might give this a go and also add a pair of diodes in the feedback path ala Muffer or at the output  to ground, don't forget the coil (see link)!

+1 on that.
even if you get interference ,you'll likely be stuck with a specific station / spot on the dial. with a radio at an input you can easily dial up static or npr or whatever you like as well as plug in an mp3 player with 'noise' recordings in a loop or even sound effects recordings. you won't be tied to the specific quality of noise you randomly pick up. much more dependable that way. i'd maybee just opt for an 1/8" input jack for a mp3 player into parallel path with your signal. add a volume control and a footswitch to switch it on and off... even better put it into a wah shell and fade it in/out...a wah would be big enough to just stick your mp3 player inside of with a modified bottom plate for easy access. jack on a pcb inside the wah, no drilling...

With a custom variable capacitor expression pedal to change the channels!

Or.........hire a midget dressed as one of the seven dwarves! That will surely add drama and intensity to the stage show!
I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

Timd has done this or something very similar. You might want to PM him.

This one: https://www.youtube.com/watch?v=SEhFU5hfoZs I think it uses a real radio.

You could just not ground your enclosure, then wire it to the input of your fuzz.
If at first you don't succeed... use bigger transistors!
