Guitar pedal effect - overdrive. Westwood is a touch sensitive translucent overdrive manipulator. This mild-mannered light- to medium-gain overdrive with active EQ controls will still knock the socks right off your trusty low-wattage combo amp, pushing it into anything from cutting, edge-of-breakup rhythm tones, all the way to articulate, singing lead tones stacked high with pleasing even-order harmonics and sweet, sweet sustain.
