* Get close to the microphone. No other technique has a big an impact on feedback. Each halving of distance is approximately another 6 dB of gain before feedback. This means that the difference between working a microphone at 2 inches, and 1/4 inch is 18dB! | * Get close to the microphone. No other technique has a big an impact on feedback.

* Use a directional microphone. Hypercardioid is better than cardioid, which is way better than omnidirectional. All sound waves impinging on the microphone from a direction other than the intended signal is "noise" and will lower the threshold of feedback. | * Use a directional microphone.
