HeadRush Slammer Compressor

The Slammer Compressor is a compressor model made by HeadRush, offered in stompbox form within the company's model range. HeadRush describes it as a "component level model of a compressor often used with higher gain amps," which places it as a modeled take on the kind of compressor players commonly run in front of a driven amp rather than a standalone hardware pedal with its own circuit¹.

What it does

As a compressor, the Slammer's job is to even out the dynamic range of your playing, lifting quiet notes and taming loud ones. What sets it apart, according to HeadRush, is how it handles pick attack: "This compressor will do its best to retain LOTS of transients even with quicker attack settings"¹. In practical terms, that means the model is designed to keep the front edge of each note audible even when compression is set to react fast, so your playing does not flatten out into an undifferentiated sustain.

The maker's note that it is "often used with higher gain amps" points to its intended place in a signal chain: ahead of a driven or distorted amp, where a compressor can tighten the response and even out the input the amp receives. Players comparing compressor models may also want to look at the HeadRush Pressor, HeadRush's other compressor offering, or the broader range of compressor pedals for standalone hardware alternatives¹.
