This article over at cycling74 is a few months old now, but is a pretty good intro to using MaxMSP apps to process "real" instruments (a guitar in this case).
It starts off with an overview of the hardware required - guitar (obviously), input device, mixer/pre-amp, etc...
It then takes you through the creation of simple, stomp-box like, effects. The first one is a chorus effect which you basically create by using the existing help files (just a bit of copy and paste).
Other effects created are an "auto-stutter" which samples small snippets of an incoming audio signal and an envelope follower which is used to control the settings for a filter depending upon the level of the audio signal.
