Back in 1991 BOSS released the Metal Zone. A classic pedal full of powerful tones that needs to be tamed and tethered in order to be understood and used successfully (in my opinion). The Metal Zone has stood the test of time and this year BOSS celebrates its 30th Anniversary with this commemorative release in basic black and grey. Very cool. And very rocking! This is a pedal for the guitarist who has everything - or not quite. Happy Anniversary BOSS and the MT-2. Rock on.
