At many moments, feedback is unwanted, but when it's controlled feedback, it can be pretty cool. Electric guitarists often achieve this by standing in front of an overdriven amplifier at high volume or by opting for a specially built-in device in their guitar. If you're not playing at high volume and/or don't want to make modifications to your guitar, Digitech offers the solution. The Digitech FreqOut is subtitled "Natural Feedback Creator". If you understand some English, it becomes clear: the Digitech FreqOut produces a natural feedback sound.
