Preamp

Preamp products raise and shape an instrument signal before it reaches an amplifier, recorder, mixer or power stage. They may add EQ, gain, instrument-specific voicing, balanced outputs, cabinet filtering or a direct path. Check input impedance, headroom, noise, output level and whether the unit expects an effects return, interface, PA or real cabinet. A preamp can be an always-on foundation or a complete direct rig, but the routing should be confirmed first.
