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 Valco Under Pressure is a Ross-style analog compressor pedal from the revived Valco brand, using Sustain, Attack, and Level controls to shape a quiet, smooth, transparent compression rather than an obviously colored vintage squash. Sustain sets how long notes are held and compressed, Attack shapes the initial pick transient's tonal character, and Level compensates output volume for the gain reduction. True bypass keeps the signal clean when off. Reviewers describe it as an excellent compressor and sustainer that rivals pedals costing twice as much, prized for how quietly and smoothly it evens out dynamics without drawing attention to itself. It works especially well for country chicken-pickin' and any playing style where a player needs to step out cleanly above the mix for a solo without the compression itself becoming audible. It suits players wanting genuinely transparent, quiet Ross-style compression at an affordable price rather than a heavily colored vintage-voiced squash.
