Often described as the first great sounding solid state amplifier, the Beta was a revolutionary design when first launched. The unique analog MOSFET design provides a wide range of tones from clean to a distinctive fuzz like distortion that cleans up with the instrument volume control.

The Beta features two independent channels each with a full set of controls that can be used separately or blended using the optional foot switch (see other listings for bundled foot switch options). Three effect loops provide a multitude of ways to integrate effects into your sound.

The PL20 is a standard as 3U 19” rack mount format.
