a buffer is a device that lowers the impedence of your signal so that it can pass through your pedals and cables without loosing treble. This is commonly referred to as "tonesuck". Buffers can counteract the effects of tonesuck and bring added clarity and treble response to your sound. Put a buffer at the beginning of your chain and you will instantly have improved signal integrity and regain your lost treble."
