A used Maestro Invader Distortion in Very Good condition with minor signs of handling and use. 

FROM GIBSON:

The Maestro Invader Distortion is a high-gain, all-analog modern distortion pedal with a heavy, aggressive, dominant sonic character and loads of rich harmonics. With the Maestro Invader Distortion, users can generate a wide range of distorted sounds. The 3-knob control layout gives users intuitive control over Gain (distortion amount), Tone, and output Level, with more than enough volume on tap to easily exceed unity gain when you want to. Users can also engage a built-in noise gate with the top panel toggle switch. An internal trim pot mounted on the circuit board inside the pedal allows the user to adjust the level of the noise gate's Threshold. The true bypass footswitch triggers the LED lights in the bugles in the Maestro logo when it’s on, so you’ll always know when the effect is active.
