I was playing a Fender Tele Thinline today at Guitar Center through a Peavey Valveking 2X12 combo. I'm thinking about buying one of them sometime because it played smooth and fast and the tone was awesome. There was one thing I didn't like though, when I dialed the reverb past half way there was so much feedback. How could you make it so there isn't any feedback or just hardly any? Could I use a gate for it?
