TTONE Effect Pedal Looper Guitar Pedals Loop Foot Switch True Bypass Mini Looping Switcher Chrome This is an incredibly small true-bypass looper box from Keeley Electronics! This little wonder is only 1.5 inches wide and 3 2/3 inches long. In particular Vintage wahs, echoes, phasers, fuzz face type pedals, or even new effects that might have a weak bypass system. These elderly effects rob tone when they are off. Now you can make them truly bypassed when off with this little box. Route selection, suitable for no direct effect :For example, bass guitar pedals etc.
