AM receiver pedal

[Branimir]

i've searched the forums but all i could find was people having issues with their effects/amps picking up AM radio...



i would like to build a circuit that would pick up AM radio signals, with guitar's pickups serving as an antenna... i know i could just by an AM radio, but I like that trashy badly demodulated thing that sometimes occurs when using badly constructed amps or effects... so  hifi - well reception thing is not needed 

i'm guessing just a random opamp type circuit with diode clippers should do it (dist+)? i'm not experienced in RF so i hope someone would help me
would be nice to put in one the pedalboard to engage at some part of the songs to pickup random radio programme and using it as a part of performance...

my dad had a saying: "when you're building an amplifier it is most likely the first time you turn it on - you'll have a really good receiver, on the other hand when you're building a receiver, most of the time you get an amplifier" - his words of wisdom on building and debugging  electronic circuits...

just build one of these


I owned one a long time ago and the radio signal was always louder then any bass signal.  Of course it was FM. 


It's an intriguing idea.   My first thoughts were that if you were trying to use it during performance, you'd only be successful if there was a strong radio signal near wherever you are performing.  Adjusting the frequency somehow would be essential.    Also, you'll want a damn good bypass. 

Why not just find an old handheld reciever and mod it for 1/4" ins and outs.

I don't know if this helps, but I'm building a fuzz that taps into various points of an AM radio PCB/kit.

Actually, it is five hemmo fuzzes...
