When running a pedal board with more than one or two effects, something called “capacitance” happens. This natural problem happens due to the amount of cable or line that you signal has to travel through. The result is a very audible amount of high-end loss, weak signal, flabby bass and uncharacteristic pickup behavior in guitars. A Buffer, or Buffered Bypass Pedal, can help maintain your core tone when running through lengths of pedals and cables. They help drive long cable lengths by converting your guitar signal to a lower impedance. Thus giving you the final result of clear, natural tone that sounds like you're plugged straight into your amp no matter how many pedals you use.
A great example of a Buffer is the JHS Little Black Buffer, and its available at Guitar FX Direct, the UK's leading boutique FX pedal specialist. Order today and enjoy free UK delivery.
