The Brass Knuckle uses an all-tube signal path to create the harmonically rich overdrive tones only tubes can. Although based on the much-revered British amps from the late 60s to early 80s, the circuit has been modified to create everything from classic-styled crunch to searing saturated lead tones, all dripping with pleasing harmonics. This pedal does not “clean up” in the traditional sense, rather it is “driven” from the get go and responds beautifully to the player’s touch on low to mid gain settings whilst retaining harmonic content. You could say it’s always just a little angry, but can be tamed by anyone willing to explore different guitar volume settings. Of course, it’s always ready to explode back to life as soon as pick attack and/or guitar volume is increased.
