FX Audio TUBE-03 Preamp Buffer

An inexpensive addition to your hi-fi system, the FX Audio TUBE-03 aims to add a pleasant amount of color and warmth to your music. Compared to a previous model, the TUBE-01, this preamp buffer features new bass and treble dials that allow you to fine-tune the sound to suit your preferences. The front panel has a toggle on-and-off switch and a large volume knob, and on top you’ll find a pair of 6J1 tubes that can easily be replaced with other tubes to achieve a different sound signature.
