Buffer/Preamp

Buffer/Preamp



A buffer is an important tool to combat tone loss with long cable runs or in signal chains running lots of true bypass pedals. With its high 1 Mohm input impedance and low 100 ohm output impedance, the EarthQuaker Devices® Buffer/Preamp will restore your tonal integrity and give you back the clear and dynamic signal you deserve and your amp craves. Want more? Not only will it restore high end loss, this device has a little trick up its sleeve that will also give your low end a subtle, yet powerful, little kick for some added dimension.

    Power

    This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!

  • All our devices come with a limited lifetime warranty. If it breaks, we will fix it. Should you encounter any issues, please visit earthquakerdevices.com/support.
