so i just got this 10 watt from the goodwill for about 30 bucks and i'm having a little trouble keeping the feedback level down when i plug my acoustic in.
i've tried changing the phase in and out and the only thing that helps is taking the bass on my eq all the way down, which gives me horrible tone. any help?
also, can anyone tell me why i'm picking up the radio on the amp?
whenever i turn it on i hear my local sports radio, and the strings on my guitar are acting like antenae cuz when i dull them with my hand the station comes in and out.

Never heard of anyone picking up a radio station before. What guitar and electronics do you have?
