Lab Ratz 3D Boum Warming Unit
Lab Ratz 3d · pedal
Lab Ratz 3D is a small, niche effects builder with limited documented history, and the Boum Warming Unit's name suggests a pedal or outboard device meant to add warmth or saturation to a signal, the word boum evoking a French origin or naming influence, though the exact circuit function and whether it targets guitar, bass, or a broader studio signal path isn't confirmed from available sources. Warming units in general terms typically add subtle harmonic saturation or gentle compression rather than overt distortion, positioning this device closer to a tone-coloring tool than a dirt pedal.
