The C4 4-knob Compressor has knobs for Sustain and Level just like the original two-knob version, but the Input Clipping and Attack controls are now controlled by knobs on top of the pedal rather than with trim pots inside the pedal as with the 2-knob version. This 4-knob version is perfect for high output guitars, bases, line level instruments, recording, etc.
The Keeley Compressor effect has nothing but tone tested components and has TRUE BYPASS switching! Effect switching incorporates a triple pole-double throw switch! You will have clean unaffected sound when in the bypass mode AND an LED for effect indication. Metal film resistors and capacitors ensure the cleanest compressor on the market. Hand matched transistors to less than 1% tolerance ensures you get a perfectly compressed signal, no chance for unwanted distortions.
Why does this compressor sound so good? Careful selection of parts. The output transistors are carefully matched transistors. They use only the best components in the construction. Metal Film Resistors and capacitors are used throughout the design. It also has a true bypass switching circuit. This makes sure you have absolutely no tone loss or signal reduction through my pedal in the off/bypass mode. This is a very expensive switch but is well worth the tonal difference.
