Reviews

  • "This pedal takes us into simple, unfussy, relatively low-gain overdrive territory. The gain and level controls enable you to balance the level of drive with the overall volume you want, while the tone pot offers global control of the EQ – relatively more dark or bright, however you like it. And that's it: super simple, no fussing.”

  • "With three triangulated knobs for level, gain and tone and a green metal-flake finish, the Grid Slammer pays homage to the classic Tube Screamer pedal and its countless variants. But that’s essentially where the similarities end. Instead of a narrow and nasal midrange boost, the Grid Slammer overdrives and shapes the entire sound, with no bass attenuation. Through a clean channel, the Grid Slammer enriches the tonal spectrum, vastly increases sustain and adds deliciously warm, tube-like grit and girth. When combined with an overdriven amp, this pedal is capable of producing tones that are shockingly close to Mesa’s legendary Mark II C+, keeping the bass tight, accentuating the mids with a chunky grind, and turning the upper mids and highs into a magical amalgamation of surreal overtones and vocal presence.”

  • "The dynamic responsiveness of the Grid Slammer is pronounced when playing simple blues progressions through single-coils and a clean Fender amp. The pedal has a very natural response to picking dynamics, and you can ease up on picking intensity without losing any crispness or sustain. Volume-knob jockeys will rejoice at its ability to go from snarling to a quiet purr by simply backing off the volume and letting up on string attack and vice versa. Though it doesn’t serve up heaps of gain for, say, the heaviest late-’70s and ’80s rock, the Grid Slammer does move from the brash tones of classic AC/DC to bigger-than-Texas blues-lead tones with ease. And though it doesn’t have a ton of gain on tap, fans of heavier music shouldn’t dismiss Grid Slammer too hastily, because it’s a very powerful tool for giving your tone a much more focused punch and tightening up high-gain amps that are a little flabby in the low end.”
