The Grunger is a tupe powered boost pedal from French boutique manufacturer Sabelya. This is a pedal that will serve to amplify the signal of your guitar by coloring it. We are not in the category of transparent boosts. On the contrary! The Grunger is made to bring color to your sound.

The very neat interior of the pedal:

Until the next gear review or interview, keep on playing the guitar!
