Slab
Concrete Sound Lab's Slab is a gritty, versatile tone-shaping powerhouse that'll inject your guitar rig with a healthy dose of lo-fi attitude. This all-analog pedal packs a JFET preamp that delivers a rich, tube-like overdrive, with a responsive silicon bipolar transistor output stage that can push the gain into fuzz territory. The real magic lies in Slab's flexible tone-sculpting controls. The pre-gain tone stack lets you emphasize specific frequency ranges, shaping the texture and character of the overdriven sound. Meanwhile, the post-gain low-pass filter tames any unwanted harshness, allowing you to dial in the perfect amount of grit and smoothness. But Slab doesn't stop there – it also features a footswitch-activated JFET boost that can overdrive the preamp for even more gain and harmonic saturation. This makes Slab a versatile workhorse, capable of everything from clean boost to raging fuzz, with a wealth of in-between tones to explore. Concrete Sound Lab has meticulously crafted Slab, with each transistor hand-tested and every pedal calibrated for optimal performance. The all-through-hole construction ensures durability and reliability, while the sleek, understated design will look right at home on any pedalboard. Whether you're chasing vintage-inspired dirt, modern high-gain tones, or anything in between, Slab is a must-try for guitarists seeking a dynamic, expressive gain pedal that can adapt to any musical situation.
