Guitarist Josh Smith demonstrates the AboveGroundFX Compressor pedal. The OTA-based Compressor circuit focuses on altering just the amplitude of the signal not the bandwidth. This combined with a slightly slower response time means none of the tone-suck and internal noise associated with most compressor pedals. This kind of superior performance isn't by accident. Peña's singular focus on perfect circuit layout means that signal interference is minimized to the point that no additional tone-killing noise filtering is required.
