EFFECT PEDAL (OTHERS) 'If you like to have several pedals and you notice your signal is somewhat low, you may be suffering from ''capacitance''. This is because the signal from the instrument traverses long lengths of cables not to mention poor actuation of certain pedals. Added to this is the belief that True Bypass is good when in reality it is worse than you imagine. The Little Black Buffer supplies a perfect input impedance to finally give you a clean and natural tone, without loss. As if the guitar was connected to the amplifier. It does not have any switches or controls, just plug the instrument into the Little Black Buffer and from there to the rest of the pedals. It operates at standard negative 9V.'
