hi, i was wondering if it was possible to add a speaker to this amp so that you could hook it up to your guitar or something like that?

this looks ok, but from radioshack it will be something like 25 dollars.

i bought a 5 dollar personal radio and found out how to hack it to add a male audio jack. it goes loud. srry, i didnt take many pics along the way. if i did i would put it up here…

how much louder will this amp be able to amplify sound, 2X 4X, Higher? Lower?

Im sorry but this is not difficult but it is very similar to the smoky amp which i have modded and im only in secondry school. I think people that cant build it should keep their opinions to themselves cause there only messing it up for the rest of us.

I bet anyone who gets caught at the airport with any of the minty devices probably will not be having a fun time tring to explain that it is only a MP3 player and amp.

This seems way similar to the Smokey Cigarette Amp (http://store.smokeyamps.com/catalog/product_info.php?products_id=31) I think I might make this in a Cigarette pack with plexy glass inside to prevent crushing. Cause you always need a mint after a smoke anyway. That would turn more heads the the headphone into the altoids tin. I could even save a space for a cig or two.

and don’t smoke. It’s bad for you ^_^
