BOSS GE-7 Equalizer

The BOSS GE-7 Equalizer is a standard pedal for guitarists seeking detailed control over their instrument's tone. This pedal features seven frequency bands specifically chosen for guitar applications, providing a practical tool for shaping sound and addressing tonal issues during live performances. Each of the seven bands - 100 Hz, 200 Hz, 400 Hz, 800 Hz, 1.6 kHz, 3.2 kHz, and 6.4 kHz - can be independently adjusted by up to ±15 dB, allowing for both subtle and significant alterations to the frequency response.

The inclusion of an independent level control further enhances the pedal's utility. This slider allows for an overall boost or cut of the signal by ±15 dB. This can be used to match the volume level when the effect is engaged or bypassed, or to provide a clean volume increase when needed.

The GE-7 offers precise tone shaping capabilities through its graphic equalisation circuit. This design enables users to make real-time adjustments to their sound. For example, the lower frequency bands can be reduced to minimise unwanted low-end noise, or increased to add warmth. Boosting the midrange frequencies can help a guitar stand out in a mix, while adjusting the higher frequencies can add clarity and definition. The first six frequency bands (100 Hz to 3.2 kHz) utilise peaking filters, which focus the adjustment around a specific centre frequency. The highest band at 6.4 kHz employs a shelving filter, which provides a more gradual adjustment of the treble frequencies.

The wide ±15 dB adjustment range for each frequency band provides considerable flexibility in sound design. This allows guitarists to make subtle enhancements to their existing tone or to create more dramatic sonic changes. The level slider's boost capability also means the GE-7 can function as a clean gain boost, useful for pushing an amplifier into overdrive or increasing volume for solos.

The GE-7 is a versatile tool with multiple applications for guitarists. It can be used to fine-tune the inherent sound of different guitar pickups. Placing the GE-7 before overdrive or distortion pedals can significantly alter their character, affecting both the tonal balance and the amount of drive produced at different frequencies. Additionally, the GE-7 can serve as a compact preamp for acoustic-electric guitars, allowing for tone sweetening and the reduction of frequencies that may cause feedback on stage. Its straightforward design and effective controls make the BOSS GE-7 a valuable addition to any guitarist's pedalboard.
