What is the cheapest way to get started using midi guitar?
Used equipment is always a good place to start if you have financial limitations (don’t we all). The Roland GR-30 can go for $200 dollars and has plenty to start with. An inexpensive guitar with a Hex pickup on it is going to be much harder to find. The most cost effective way to go is probably a used GK-2A mounted to an older guitar that has good “feel”. It won’t be pretty but pretty costs.
