Preamp & Buffer

Shape the front end of your rig with preamps, buffers and devices that combine these functions with other processing. Examples include Fire-Eye Red-Eye acoustic preamps, Jad & Freer CAPO bass processing and compact tuners with built-in buffers.

Start with the instrument and the input it needs to reach. Compare gain and tone controls, DI outputs, effects loops and power requirements, while checking whether the device is intended for acoustic, bass or electric guitar use.
