This is what I will be using until I have enough to buy a real P.A. system.
This is a Fender acoustic amp, which I will use for both my guitar and mic.
It sounds okay, but as it's not a P.A. system, it's easy to get that horrid feedback from the mic if the volume is higher than 4 1/2.
And this is my Ovation:
I gotta stock up on 9 volts, which go inside the built-in tuner. If I forget to unplug the guitar from the amp when not in use, it drains the battery, which needs to power the acoustic pickup!
