Tascam have claimed that their mp3 phrase trainer - the MPGT1 -can remove the guitar part from a stereo mix.
There are quite a few bits of hardware (ie Karaoke) and software that claim they can remove vocals from a stereo mix - either through the attenuation of frequencies as Kris suggests (and this is hard to do as you will really need to ride a multi band eq in real time across a lot of frequencies where the gain is changing) or by inverting the signal on one channel so that the two phase cancel each other in the stereo master (you can do this in Audacity or any similar bit of software btw). From what I've seen none of them are 100%. Vocals tend to be mixed centre and usually with a bit more gain then the instruments, guitar is usually panned off centre. What you are effectively doing in vocal cancelling is wiping out the centre channel - and that means anything that is there: vocals, drums, anything, and rendering back to a much attenuated mono signal. To recover the other 'lost' information means you have to make another pass through and apply suitable low band pass filtering to bring those particular frequency ranges back into the mix. (Its usually low as it tends to be kick drums and bass frequencies that are most evident in the centre channel.) Centre channel sort of works then because the left and right channels are pretty much identical. (Rarely totally identical though as usually reverb, or some other buss type effect is added in different amounts to left and right channel.) Inverting one will cancel (most of) the other. Instruments off centre though don't give identical left and right channel waveform images. Inversion here won't result in full cut and may end up as a messy compromise. To be honest, well if we can't vocal cancel then guitar canceling seems even less likely to work really well. Having said that Tascam's bit is probably adequate for a riff tracker where you just need most of the guitar attenuated out so that you can jam over the top of it. Anyway if you don't want to try the Tascam you can always try phase inversion using Audacity or similar - won't be perfect but could be good enough.
