The Ashly SG33 is a vintage dual-channel analog noise gate designed to reduce unwanted noise, microphone bleed, and background interference in recording and live sound applications. With two independent channels and hands-on controls, the SG33 offers a straightforward way to manage signal levels and improve separation between sound sources.

The SG33 is particularly useful for tightening up drum recordings, controlling microphone leakage, reducing amplifier noise, and cleaning up individual channels in complex mixes. Its analog signal path and dedicated hardware controls make it easy to integrate into traditional recording setups or modern hybrid studios.
