But if an arrangement is fairly dense, then it might be good to take a cue from the jazz amp, and use the second parametric equalizer stage to cut some frequencies in the 500 Hz вЂ“ 1 kHz range. For example, if you wanted a sound thatвЂ™s more suitable for lead guitar, you could use one stage of parametric EQ to add a major boost around 2 kHz. The second Parametric EQ component can contribute the same kind of вЂњcharacter-orientedвЂќ boosts and cuts to your virtual cabinet. The boost around 2 kHz gives good articulation for solos, the bass boost gives a warm, sound, and the midrange dip makes room for piano, vocals, and other instruments that are in the same part of the frequency spectrum. Finally, the amp in the lower right is used by jazz guitarists. The lower left image is a high-gain, heavy-metal amp-it gives a relatively uniform response thatвЂ™s loud across the spectrum.

The upper right image is from a popular combo amp note the frequency response cut around 1 kHz, an extended high-frequency response, and a fairly even low-frequency response. The peak around 2 kHz gives a strong boost to higher frequencies, so leads can cut through a live performance or mix. The upper left image is of a popular amp used by rock lead guitarists.

Figure 2 shows the result of feeding pink noiseВ (a type of test signal thatвЂ™s like white noise, but more closely approximates how the human ear perceives sound)В through different cabinets to reveal their frequency responses the two additional stages of parametric equalization can contribute this kind of character to your virtual cabinet. The variations in a cabinetвЂ™s frequency response caused by various peaks and dips is what gives different cabinets their character. A fuller, beefier sound can be created with a boost just above your 50Hz cutoff вЂ“В approximating a closed-back sound. If you choose a high-frequency boost with a wide Q value, youвЂ™ll achieve a sound closer to that of an open-back cabinet.

Increasing the Q value widens the effect of the filter. The low frequencies you choose to remove will depend on whether you use conventional or вЂlowвЂ™ tunings, but you can safely remove everything below 50Hz. Open up the EQ controls using the Expert Panel. Here, weвЂ™ll use a Parametric EQ to replicate this effect. If we set the Reso (resonance) dial at around 0.15, weвЂ™ll get a slight boost at this frequency which ought to give some improved definition to our notes.ДЄ guitar cabinet typically wonвЂ™t reproduce frequencies much below 75Hz вЂ“В thatвЂ™s desirable for most guitarists, since frequencies below this point typically comprise booming and rumbling sounds that can muddy up a tone.

This will sharply reduce frequencies above whatever value you choose with the Cutoff dial вЂ“ try anything between 3.5kHz and 7kHz. Select LPF in the Mode options and set the Slope dial to its maximum (fully clockwise). The Pro-Filter is ideal for this, as it has a low pass filter (LPF) mode, which only allows lower frequencies through. Good guitar tone is mostly about midrange, so youвЂ™ll want to remove some higher frequencies вЂ“ in fact, many real-world guitar cabinets donвЂ™t have any response at all above 5kHz.
