Slab is a low gain dirt pedal with a range that goes from clean-ish into overdrive and fuzz/distortion.
A tube-like JFET preamp section with a James tone stack drives a responsive silicon bi-polar transistor output stage. There’s also a footswitch activated JFET boost to overdrive the preamp stage, adding more gain and harmonic saturation.
The pre-gain tone stack provides control over which frequency ranges are emphasized and is a powerful tool for shaping the texture of the overdriven sound. The post-gain tone knob is a passive low pass filter to dial back any unwanted harshness and shape the final sound.
Slab is recommended for use with guitar or bass into a traditional amplifier setup.
Slab is an all transistor design, hand soldered with all through-hole construction except for the surface mount JFETS. Every transistor is tested before soldering, and every pedal is calibrated and tested after assembly to ensure quality and consistency.
