OK, by that pharase I think you might be asking something a bit different. It sounds like what you might be saying is that you actually ARE recording in stereo right now and not quite realizing what's going on.
Are you saying you are plugging your pickup into, say, channel 1 of your 122 and nothing into channel 2, and when you record it gives you a recording that only plays back your guitar in the left channel? If so, then it's a matter of understanding and adjusting how you have your Abelton set up to record.
If the above is true, what may be happening is that Abelton is set up right now to record both inputs from your Tascam into a single stereo track. Tascam channel 1 is going to the left side of your stereo track and channel 2 to the right side. What you need to do is switch Abelton's recording settings so that each channel of the Tascam is going to a seperate mono track instead of being combined into a single stereo track. Then the Tascam channel 1 will be going to mono track 1 in Abelton and channel 2 to mono track 2.
Set up this way, your guitar on channel 1 will still be a mono (meaning single source) signal, but now you'll be able to use the Pan control on Ableton's Track 1 to pan the guitar anywhere you want in the Left/Right stereo field.
Additionally, with this setup you can now use your mic in channel 2 simultaneously and record your vocals to track 2 in Ableton, and also be able to independantly pan those wherever you want in the stereo playback.
I've not use the Ableton software myself so I can't tell you exactly where the controls are located for adjusting the recording type from stereo to mono, but that capability is in there somewhere, I'm sure. Maybe another Ableton user can chime in on that one.
HTH,
