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.
The MXR Dyna Comp is one of the most iconic and recognizable guitar compressors, a colorful, character-rich pedal rather than a transparent one. Built on the Ross-derived OTA circuit with simple Output and Sensitivity controls, it behaves much like a limiter, taming pick-attack transients so the percussive pop levels out with the note while a long release adds body and sustain to fading notes. It rolls off some high harmonics and low end for a perceived midrange boost, giving it an unmistakable squash. It is a Nashville staple, its fast attack accentuating the pluck and cluck of chicken-picking and its sustain fattening pedal-steel-style bends, and it also underpins soaring solos in the David Gilmour vein. Beloved for its distinctive flavored squash, it suits country, funk, blues, and rock players who want a compressor with a strong, musical personality.
