The CastleRock Guitar 7-Band EQ Pedal gives you precise control over your sound. Each of the 7 EQ filters allows for 10dB of boost or cut to eliminate muddy bass, honky midrange, nasty high end and allow some breathing room for your sound. Suddenly your guitar sounds more articulate and precise. An overall volume control allows you to match the original signal to the post EQ signal. The CastleRock 7-Band EQ pedal features an all metal chassis, rubber footswitch tread, and non slip rubber back.
