I have these Equipments for Live performance -

1. Fender Acoustic 100 - 100-watt Acoustic Amp
2. Boss RC-30 Loop Station
3. Yamaha Acoustic guitar
4. 2 Mics (1 is Sennheiser and other is Behringer Ultravoice Xm8500 Dynamic Vocal Microphone, Cardioid)

I need some advice on what settings should I set in the Amp, looper, and Guitar for best live sounds.
Any advice on getting some more instruments for enhancing the sound quality?

I like to play Ed-Sheeran songs and would really appreciate any tips.
