Barber Gain Changer is Here! Measuring only 2.3” wide, the NEW Barber Gain-Changer 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 unLimiTeD distortion. Pop over to the other toggle-switch and you can volley between the flat sweet-EQ of the LTD SR , the vintage snarling-fat-EQ of our classic LTD v2 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. – Goto Product!
