Set your EQ
Turn the low knob clockwise to a setting of 5 to 7. This varies depending on which guitar you are using, and which pickup sends a signal to the amplifier. The goal of the low range setting is to dial in very low frequencies without causing the amp speaker to vibrate.
Turn the intermediate level knob clockwise to a setting of 7 or higher. Many rock and metal guitarists choose to scoop all the midrange out of the tone and think it will make the guitar sound bigger. This is a mistake; My middle class is where your guitar sound lives.
Turn the high frequency knob clockwise to a level of 5 to 7. Again, this varies depending on your taste and the type of guitar you use. The key with the high quality setting is to dial in enough without letting the tone sound metallic or nasal.
Setting of lead tone and pure tone
Turn the gain knob to a setting of 4 to 6. Many guitarists make the mistake of turning this knob all the way, which will kill the clarity of your tone
Turn the post-amplifier channel (the knob directly to the right of the angle). pre-gain channel), clockwise to a setting of 2 to 3. This is essentially a volume knob, so set it as high as you want without causing feedback.
Turn your pure tone (the leftmost knob) clockwise to a setting of approximately 80 percent of the lead tone volume.
Find the ‘Modern / Vintage’ button and select which setting you prefer. The modern tone is sharper at the high end, while the tap tone has more low and mid-level harmonics. Peavey Rage 158 amps are cheap and small, making them a favorite among guitar players and those on a short budget. So that’s why they’re often a guitarist’s first practice palette to learn things like good tone and quality construction. Because Rage is cheap, there is often a reputation for sounding cheap and amateurish. But with a little patience, experimentation with the equalizer and good guitar technique, any guitarist can use Rage to achieve tones from the sparkling pure to the hellish high gain.
