      Well, I’m guessing on what you’ve used to connect it all up, but (to be on the safe side), I suggest cease and desist 🙂

      Your problem is that you have a stereo device (CD) and a mono device (guitar) fighting to make their way out of another stereo device (your headphones). The fact that you can hear the guitar (pickups are an incredibly feeble source) surprises me, but there is the possibility I suppose to damage something (any amp in the way, the ‘phone speakers, your ears).

      A mono jack (socket, and your instrument cable) has a source (or “hot”) tip and ground sleeve. A CD player’s ‘phones out has a “left” tip, a “right” ring and a ground sleeve. If you’ve used a stereo jack — 2 stereo jack splitter, then your ‘phones (tip, ring and sleeve) are in one end of the splitter and your CD ‘phones out (tip, ring and sleeve) is in one of the other ends. This should sound fine if left like that. As soon as you plug the guitar cable in, you’re throwing into the mix a mono tip and the ground sleeve is touching the splitter’s “right channel” ring receptor. Having grounded the right channel, you’ll hear that horrible “duuuur” noise you get if you press your thumb on the tip of a jacklead you’ve left plugged in the amp. You also won’t hear the right side of your CD, at the least.

      A lot depends on what sort of splitter you’ve used. What’s male and what’s female? Is it stereo-stereo, stereo-mono?

      Thanks for the help all.
      I found some plugs and adapters lying around the house, and gave it a try. it worked……..sorta. The guitar works alright, but when plug in the stereo I get a loud buzz, and can barely hear the CD in the background.
      I’ll try a headphone amp device.

      Bass is right you need some kind of signal boost for the guitar, if you are looking for a christmas present, tell someone to get you a Korg Pandora PX4.
      It’s a band in a box with amp sims and excellent guitar effects, also has a CD input you can jam along with, or if you have a PC get yourself a Line 6 Guitar Port.

      Just plugging a guitar into headphones isn’t much use, unless I’m missing something obvious. The output just isn’t good enough. What you could use (costs more than a splitter cable, unfortunately) is either something like the Pocket Rock-it headphone amp (guitar and CD input) or any amp with CD input and ‘phones out – such as the Marshall MG10CD.

      I imagine there are MultiFX/modeller units that also can do this job.
