I recently bought an Electro Harmonix B9 organ machine guitar pedal, and its limited, but you could get away with playing it live for certain parts. I'm not that sensitive a player, but some of the samples by better, more polished guitarists are quite good. I may use it some in place of MIDI keys which I use quite a bit of in my compositions. Just for creating different sounds. It has a Melotron setting and that actually is really useful and has given me some pretty unique sounding parts (unique is sometimes very very cool) It has a good Farfisa sound as well. The "Lord Purple" setting is really good, but you have to use an external leslie setting to really get a realistic sound. Whats cool about the pedal is you can bend notes while soloing and its works and that makes the organ sound really unique. A four piece band with 2 guitars could add fair keys and not have to use a keyboard, and they would probably pull off cover tunes pretty well.
