I've seen a few videos recently of guitarists using what I'm assuming is a synth/midi pedal that changes your notes to any number of other instruments, I've heard some that make it sound like an organ, some that make it sound like a violin. I was wondering if these are just odd multi-effects boards or something else and how much they cost.
The majority of popular midi controllers and synthesizers (pickup and controller) cost a ton.
Check out Roland GR stuff (GR-20, GR-33 etc etc).
The Axon AX100MKII is much better than the Roland.
