Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.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 Custom Shop CSP028 '76 Vintage Dyna Comp is a faithful recreation of the original 1976 Dyna Comp compressor, built around the same CA3080 integrated circuit for quiet operation and relatively transparent, dynamic compression. It thickens and evens out the guitar signal, raising quiet notes and leveling loud peaks into a rich, full-bodied sustain, with a note attack that can snap forward with a pronounced pick transient while still sounding natural rather than clamped-down. Pushed hard, it produces a squishy, almost backward-sounding swell as the compressor's gain rushes in after the initial attack. It is closely associated with the slashing, squashed funk-rock tone of Adrian Belew and Andy Summers, and also suits huge, sustained clean tones in the style of David Gilmour.
