This pedal is in very good condition with the only sign of cosmetic wear being the velcro on the backside. From Barber Electronics' website,

"Measuring only 2.3” wide, the NEW Barber Gain-Changer SR harnesses a vast spectrum of EQ and gain. Flick the toggle one way and you have sweet very low-gain overdrive, flick it the other way and you get wildly charged harmonic content of our much praised distortion. Pop over to the other toggle-switch and you can volley between the flat sweet-EQ of the , the vintage snarling-fat-EQ of our classic or a new voice that combines flat EQ with a little added fatness. Combine all these different options together and you have a super-versatile harmonic beast. Our goal was to shrink the size of our pedals and retain all the ultra-high quality electronics and build quality that we are world famous for. In the end, it’s almost impossible to miss the target if you are shopping for a new overdrive for your rig, “it’s like shooting fish in a barrel Jethro.”

The Gain-Changer SR has real honest solder lugs for jacks, True-bypass footswitch, toggles and pots. There are no worries about PCB mounted thru-panel parts that can’t be serviced on the road, or that lead to high cost repairs. Nothing but the best tried and true hand-built methods adorn the interior of the Barber Electronics Gain-Changer SR. The Gain-Changer SR has a generous 2 1/2” of clearance between the front edge of the footswitch and the back edge of the knobs, no more worries about changing your settings with each click of your footswitch. Buy a hand-built Barber Gain-Changer SR, and enter a world of immense overdrive possibilities."
