The Keeley Compressor GC-2 Limiting Amplifier is built around the exotic and extremely high-fidelity THAT Corp. 4320. Think of it as very musical studio-grade compressor in stomp box format! It uses high performance Voltage Controlled Amplifiers, on board true-RMS detector, and ultra-high performance op-amps to bring you the very best quality. This type of compressor gives you precise control and very musical results. This along with a full frequency range means that the GC-2 Limiting Amplifier compressor is well suited for guitar, keyboards, drum machines and, really, anything you can throw at it. The Keeley GC-2 Limiting Amplifier is both musical and transparent. Where our older compressors were based on the CA3080 or the LM13700 and are perfect for that “Compressor Effect” and are still in use by tens of thousands of players, the new Keeley GC-2 is a different style compressor, aimed at being the ultimate in low noise and transparency. Not only can it handle astonishingly large signals, but it has an incredible bandwidth of over 20 KHz. No detail in your guitar’s tone will be lost. The Keeley GC-2 will be a sound investment in your tone–you now have genuine rack-mount quality at your feet.
