1. Extremely Obvious, does not need a instructable.
2. You will most likely get worse sound quality than if you had used an amplifier.
3. Almost all guitar amplifiers are monaural, so you will lose the right channel altogether.
4. MP3 players have an amplifier built in, making their output voltage higher than a guitar's pick-ups.  This voltage can cause damage to the preamplifier of your guitar amp.

Not losing the right channel , but even my DSP amp has a TRS input for my android or anything that has audio , and combines left and right .

 I agree there is nothing difficult about connecting a MP3 player to any kind of amp. I also agree that the sound quality will suffer by losing one side of the audio unless you use an adapter to turn a stereo signal into a mono signal. But it will still not sound as good.

Use, instead, a 1/8" stereo to left & right RCA jack cable (a buck or so at RadioShack), and run the output of your mp3 player (or mp3-playing cell phone, like I did a couple of years ago) into the AUX input of your component stereo or home theater unit. Works the same way if you want to route the line out of your sound card into your stereo -- who ever needed computer speakers in the first place?

This would be fun. But so would buying an adapter for a dollar. Smarter, not harder. : )

The point is to eliminate noise or buzz, and that can be done with a humbucker guitar pickup, which is what amps use. But, don't spend that much money -- you can accomplish the same with an audio transformer. These are cheap and small (thumb-sized). Solder one side's terminals to a plug to the CD player; solder the other side's terminals to a guitar cable (or a plug that will take a guitar cable). I used this setup with "play along" CDs (karaoke for guitar). Clean!

Tried it, it sounded horrible! no amount of tweaking would make the sound anywhere close to even the £1 headphones from the pound shops.

The problem with this is that amps almost always have mono inputs, so you'll only get the left channel of sound.

i'm really iffy about this b/c i know that amps work by amplifying the power coming out of the gutiar, which is minimally small. the power coming out of the ipod has to be many times more powerful than the guitar (which doesnt even put out enough for a minor shock), so wouldnt that mean you might blow out ur amp? a personal comment or message about this would be nice, cuz i'm prolly never going to check his ible again!

Well, it's simple, you connect an audio source to amplifier and then you can hear music! What a surprise... This could be good idea if you build a dock to your amplifier which gives power to your Mp3 while listening but otherwise this instructable is quite useless.

you can get a dock for the zune that gives it power while its playing only problem is that it needs a usb port but it has an adapter for that too, u would need a plug for the amp too so it all works out

anyone with any concept of line in/out, mono vs. stereo could have figured this out, but true, most people have no idea that all you need is a set of old stereo phones, snip ear muffsoff, and solder to 1/4 inch stereo jack, rat shak, bam, personaly, i just snipped two sets of phone lines, and wired them together , taped up, used 1/4 in adpt. i wonder what it would sound like using mono lines. after all you only get 1 spkr w/ amp.

lol well said... I know that this is a pretty simple concept, but most people have NO CLUE when it comes to inputs and outputs.
