In my line of work, vocal projection is everything. However, as one approaches the sunset years, one's vocal chord endurance deteriorates very quickly. I would be down with a severe sore throat (bleeding on occasions) if subjected to prolonged, unassisted loud talking. These days, I'd be arming myself with a mic to reduce this strain but maintain volume projection. However, some PA systems have no gain feature to push things through when it comes to amplification. The solution - external boosting. The JOYO Roll Boost you see here works well with a mic as it would with an electric guitar. It's a non-discriminant; it doesn't choose to boost guitar signals better than vocal signals. It just boosts anything that's plugged into it. 👍
