Originating in the USA but embraced worldwide, these pint-sized powerhouses allow sound engineers and musicians to customize their signal chain with preamps, EQs, compressors, and various other processors, all fitting neatly into a compact 500 Series rack.

Drawmer MQ-2 Motown Equaliser

The Drawmer MQ-2 is a stereo 7-band proportional-Q equaliser and compressor for the 500-series, inspired by the classic 1960s Motown EQs. It offers fully variable ±10dB boost or cut, an intuitive one-knob compressor, and a ‘CRUSH’ feature for harmonic saturation. Users can switch the processing order between EQ and compression. Designed and manufactured in the UK, the Drawmer MQ-2 delivers high-quality, low-noise performance in a two-slot 500-series module.
