With an 80W, 4 - 6L6 power section and a custom-wound transformer, the Superdrive 80 is tight and beefy with plenty of headroom. It gets the tone of the gods and exceptional pick dynamics even at conversation level. In the preamp section, 12AX7s and a 5U4 rectifier tube deliver a tight and articulate clean channel and a lusciously creamy overdrive channel. Controls for treble, mid, and bass EQ; rhythm volume; hi-gain drive; and master volume. The transformer can be switched from 4, eight, and sixteen ohms to match your speaker setup. Effects loop and a slave out connection are provided.
