If you love vacuum tubes, these pre-amps have your name on them. The TubeHead is a low-cost, two-channel vacuum tube pre-amplifier with a twist; it's designed to be adjustable from crisp, solid-state transparency to an exaggerated caricature of tube amp warmth. In between these extremes, you'll find tonal coloring options that you've never had before and sounds that mimic every tube amp you ever heard. This circuit is so versatile that you may use it in place of compressors, limiters and sustainers even though, technically, it is none of these.

Tube Sound?
In sound systems from the golden age every link in the chain had distinct "squashing" non-linearities.
How Tubes work
"Starving" tubes with low plate voltages and currents produces a caricature of tube amp warmth.
