Amp-fx Keeley Compressor clone // C4 4-Knob Version // Handmade in Berlin.
Amp-fx Keeley Compressor Clone. C4 4-Knob Version.
The holy grail of guitar compressors. Improved.
Not the most expensive, but definitely one of the best guitar compressors.
The Amp-fx improved version of the famous Keeley compressor.
Only the best components available reach the high expectations we have in an Amp-fx pedal. Handpicked, tone-tested parts leave your natural sound untouched.
On the whole we use the same high quality parts that Keeley uses for his Ross compressor clone: Panasonic metal film capacitors and low noise metal film resistors in the audio path, expensive tantalum caps for filtering
and sturdy 1/4" jacks "made in Japan". The transistors are matched to less than 1% (very important for consistent compression). The compressor is true bypass to leave your tone unaltered when switched off.
Tone tested components guarantee a clear compression.
This is what the knobs do:
Level: Adjust the volume here. Match the bypass volume with the compressed signal. You can turn it up to overdrive your amp, or you can create a lead boost for solos if you turn the sustain all the way down, and pick your preferred overdrive level.
A perfect clone of the Ross aka. Keeley compressor.
The pedal can be powered using an internal 9V battery or an external 9V Boss style (center negative) AC adapter. The battery disconnects from the circuit when you pull the input jack. This will extend the battery lifetime. The current consumption of the pedal is low. It draws only 5 milliampere.
Placement in the signal chain:
Historically, the best place for a compressor is right after the guitar. Nowadays it is popular to use after your main "tube sound" pedal. This way you can get a more smooth transition from a clean to distorted sound. The compressor also works well before a booster. However, it does not work well behind a booster. The internal CA3080 likes low level signals more. We do not recommend using the pedal after a delay, echo or in the effect loop of your amp.
