5. Gain Reduction
In the context of acoustic guitar compression settings, gain reduction refers to the amount by which the compressor reduces the level of the signal above the threshold. It is expressed as a ratio, such as 2:1, 4:1, or 10:1. A ratio of 2:1 means that for every 2 dB of signal above the threshold, the compressor will reduce the gain by 1 dB. A ratio of 4:1 means that for every 4 dB of signal above the threshold, the compressor will reduce the gain by 2 dB, and so on.
Gain reduction is an important component of acoustic guitar compression settings because it allows you to control the dynamics of your guitar sound. By reducing the gain of the loudest parts of the signal, you can create a more consistent and balanced sound. This can be useful for taming harsh peaks, adding warmth and fullness to the sound, and enhancing clarity.
The amount of gain reduction you apply will depend on the desired sound and the style of music you’re playing. For example, a subtle amount of gain reduction can be used to add warmth and fullness to a clean guitar sound, while a more aggressive amount of gain reduction can be used to create a heavily compressed and distorted sound.

6. Make-Up Gain
In the context of acoustic guitar compression settings, make-up gain plays a vital role in shaping the overall sound and dynamics of the guitar. Compression, while effective in controlling dynamics and enhancing clarity, can also lead to a reduction in the overall volume of the signal. Make-up gain is used to compensate for this loss in volume, ensuring that the compressed signal maintains a consistent level with the uncompressed signal.
The amount of make-up gain applied depends on the amount of gain reduction applied by the compressor. As a general rule, the make-up gain should be set to match the amount of gain reduction, resulting in a net gain of 0 dB. However, this can be adjusted to taste, depending on the desired sound. For example, adding more make-up gain can result in a louder, more aggressive sound, while less make-up gain can create a more subtle, compressed sound.
Make-up gain is an essential component of acoustic guitar compression settings because it allows you to control the overall level of the compressed signal. By carefully adjusting the make-up gain, you can achieve a balanced and polished sound that complements the natural tone of the guitar.
| Parameter | Effect on Sound |
|---|---|
| Gain Reduction | Reduces the level of the signal above the threshold |
| Make-Up Gain | Boosts the level of the compressed signal to compensate for gain reduction |
Understanding the relationship between gain reduction and make-up gain is crucial for getting the most out of acoustic guitar compression. By carefully adjusting both parameters, you can achieve a wide range of sounds, from subtle and transparent to heavily compressed and distorted.
In the context of acoustic guitar compression settings, the knee refers to the point at which the compressor begins to apply gain reduction. A soft knee results in a gradual transition between the compressed and uncompressed signal, while a hard knee results in an abrupt transition.
