GE-7 Equalizer

With the availability of slimmer slide potentiometers, the GE-7 was released 1981. It's got the same frequency bands as the GE-6 as well as one additional one at 6.4kHz. There is also a level control that you can use to set the difference of level between on and off mode for the pedal.

Boss Advertisement text (Internet, 2001):
Provides seven bands of equalization ranging from 100 Hz to 6.4kHz - ideal for guitar. A boost/cut of +/-15dB per band gives you complete control over your sound and helps eliminate unwanted feedback, particularly when connected after a distortion effect.

Boss Guitar Effects Guide Book vol.9 (1993):
The GE-7 has seven bands ranging from 100Hz to 6.4kHz, ideal for guitar sounds, with boost/cut of +/- 15dB per band. This lets you completely control your sound and eliminate unwanted feedback, particularly when connected after a distortion effect.

Using the GE-7

* For sharp rhythm sounds: Cut the middle frequency bands around 800Hz and boost at 1.6kHz (Fig 1: 100Hz -5, 200Hz +5, 400Hz +0, 800Hz -5, 1.6kHz +10, 3.2kHz +5, 6.4kHz +0, Level +0)
* For powerful guitar solos: Boost the middle frequency bands slightly and connect the unit after distortion and overdrive. Set the LEVEL control a bit higher than normal. (Fig 2: 100Hz +0, 200Hz +5, 400Hz +10, 800Hz +8, 1.6kHz +7, 3.2kHz +5, 6.4kHz +0, Level +3)
* For a metal sound: Cut the middle band around 800Hz and boost the lower and higher frequency bands. Place the GE-7 after the distortion or over drive unit. (Fig 3: 100Hz +10, 200Hz +10, 400Hz +0, 800Hz -5, 1.6kHz +0, 3.2kHz +10, 6.4kHz +5, Level +0)
