Keeley Compressor Plus — Compressor / Sustainer / ExpanderRobert Keeley set out over 20 years ago to build the best-sounding compressor effect possible, and the result became the most popular boutique compressor in the world — with over 132,000 units hand-built in Keeley's Oklahoma shop. The Compressor Plus is the most evolved version of that lineage, taking the acclaimed original design and adding several key features that make it more versatile and easier to use than ever.At its core the Compressor Plus is not simply a compressor — it's a compressor with an integrated expander/sustainer. It limits the peaks in your playing like any compressor would, but it also adds gain as notes naturally fade out, giving bends, leads, and sustained chords a blooming, singing quality that feels alive. Think studio-rack-quality JFET compression in a pedalboard-friendly enclosure. The result is a sound that feels professionally recorded — polished, even, and present in a mix — without sounding squashed or lifeless.The addition of a Blend control is a game-changer. Rather than applying full compression to your signal, you can mix in as much or as little compressed signal as you want alongside your dry signal, preserving natural playing dynamics and maintaining proper phase alignment. The Tone control — adapted from vintage analog delay emphasis circuits — gently recovers the high harmonics and treble that compression tends to soften, adding back sparkle and shimmer without harshness. The Release switch eliminates the guesswork of setting attack and release times by offering two positions optimized specifically for single-coil or humbucker pickups, making it effortless to transition between guitar types.It excels across a huge range of applications: Texas-style country twang, funk rhythm playing, ambient washes, loop creation, lead boost, and pushing a tube amp into natural saturation.
