This is the newest version of the Polytune that has the buffer included.  Buffers make a huge difference especially with larger pedalboards or long cable runs to bring back the high end and clarity. This listing is just for the pedal unless stated otherwise or included in the photos. All items will be shipped with insurance, and most items (typically $100 and up) will require a signature. Please see the photos for exact condition and send us a message with any questions!
