Instructables user mattthegamer463 didnt want to buy an expensive wireless guitar system so he modded a wireless mic setup he already had to do the job.

However, they are expensive, way more expensive than wireless microphone systems. In fact, if youre like me, you might happen to come into a wireless microphone system for free.
