The instrument
Designed as Boss' competitor to MXR's popular M-109 6 band equalizer the GE-6 offers six bands with frequencies 100, 200, 400, 800, 1600 and 3200 Hz. Each band can be boosted or cut by 15dB. The GE-6's center frequency is 800Hz and was chosen because this is where it has the most useful impact on the sound of an electric guitar. The other frequncies are set at octave steps from the center frequency. Boss's line of compact pedals began in 1977 with the release of six pedals: an overdrive pedal (OD-1), a phaser pedal (PH-1), a parametric equalizer called the Spectrum (SP-1), a 6-band graphic equalizer (GE-6), a compressor pedal (CS-1) and an automatic wah pedal (TW-1).
