Made like tanks, like all Boss pedals that never break! This pedal, besides being an EQ, is one of the best boosters on the market. Unbelievable, yet true! It has a great impact on the guitar's sound, and if you experiment with settings, you can create very unique sounds.
I have two in my pedalboard. One at the end, which shapes the final sound I want, and the other right after the distortion and before the delay, which I use as a booster for leads.
