Sound buffer that protects against signal amount and quality loss which happens with large pedalboards with many pedals and with long cables. This buffer compensates for the loss of the signal and can work at the beginning or at the end of the effect line and doesn’t need any controls. Thanks to the components being used, the amount of hum is minimum. RockBoard Natural Sound buffer is encased in a durable metal construction, houses In/Out Jack inputs and is powered by a 9V power supply, which is not included.
