right now i am using a v-amp2 live and love it. i set up rhythm and lead patches and switch between them via the footswitch. i was thinking of getting v-amp pro to use live and use the v-amp2 for practice. the problem? how do you switch patches on a pro? there is no footswitch connection. i assume i have to buy a midi controller? is there a cheap one that will let me change patches like the vamp2 does. i don't want the expression pedals etc just a way to switch from lead to rhythm patches on the fly. any ideas?
