If you play in a band and want to emphasize a guitar solo, for example, you may not only have to touch the volume knob on your amplifier. Try changing the frequency range of your guitar with this pedal. I can say for sure that you will hear the desired parts of the game louder and fuller. I haven't used EQ for a long time, and in retrospect I regret the years wasted like that. The Boss GE-7 is a good effect, for a good price! I recommend it to every guitarist! + Compact, strong housing, small size. - Basic noise ("blow"), easily adjustable pots.
