The Ashdown ADMS1 Studio Compressor is a bass-optimized compressor pedal from UK manufacturer Ashdown Engineering. Featuring Threshold (gate level), Ratio (compression amount), and Gain (output level) controls with factory-optimized Attack and Release settings not exposed to the user. Retains the natural tone of the instrument while controlling dynamic range. Can be inserted between instrument and amplifier or between preamp and power amp. Available from Sweetwater, Ashdown directly, and multiple international retailers.
The Keeley Compressor Good Ol' Edition is a take on Keeley's original studio-quality compressor, the pedal that helped establish the brand and became a staple on countless professional pedalboards. It provides smooth, transparent optical-style compression that adds sustain and evens out picking attack without obvious pumping or noticeable tone coloration. The classic two-knob layout keeps it simple and musical, ideal for clean funk strumming, country picking, and always-on dynamic control. It preserves the natural feel of both single-coil and humbucker guitars while smoothing transients and extending note bloom. Long regarded as a benchmark studio compressor in stompbox form, it suits players who value transparency, low noise, and dependable, set-and-forget compression.
