guitar preamps, mic preamps, and other Di devices that are going through a line-in jack are meant to be recorded mono. if you want to have stereo guitars recorded, you will have to record through your line-in jack and specify the audio to record into a stereo track. your mic jack is wired for stereo.

It helps if we know what soundcard you're using.

Most, if not all, consumer soundcards have had their analog I/O color coded in the last 5 years. For most of us, the most important colors are: Lime Green - Line Out and Light Blue - Line In. The Mic In is usually  pink in color. Note that with some soundcards and onboard audio, changing from ordinary stereo operation to surround mode (5.1, 7.1...) will cause some inputs to switch into output mode, often sacrificing the line and mic inputs.

Use the Vamp Pro's unbalanced 1/4" outs and use a good Y-cable; preferably, make one yourself if you're handy with a soldering iron. I've seen some y-cables and y-adapters that sum to mono. Remember that the tip in a stereo plug, be it 1/4" or 1/8", is always the left channel.

Hmmm...lam ko kaya stereo yung mic jack it's because it uses the middle connector for phantom power.

Actually AFAIK, the mic in for the soundcard uses a stereo jack, but only the tip is used to take in audio. The middle ring carries a DC voltage which is used by the usual condenser mics connected to the PC. Ang alam ko, the line in is stereo.

yep BAMF, yan din pagkaka-alam ko, correct me if im wrong. i used to record using an ordinary soundcard's line in.  cassette tape to hard sisk. i always get a stereo signal that way.

greenweenie, when you say you get a stereo signal thru your mic in, do you see any distinction between the left and right channel? just to take away some confusion, an identical left and right signal is still a mono signal. what do you mean when you say you get a mono signal from the line in, does the meter show only one signal coming in? if so i think there something wrong with your cables or your output.  try to experiment using a cassette or cd player. record the output thru your soundcard's line in an see if the signal is still mono.  are you using a stereo jack? if you see only one ring at the tip of your jack then it's no surprise you are getting a mono signal.

hope this helps.
