Tone King has been producing hand-crafted tube amps built by Mark Bartel out of Baltimore since 1994. The Tone King Falcon has become somewhat iconic for its television-like appearance and warm sound, as have many of the Tone King combos. A growing number of players, including Wilco's Jeff Tweedy, have started to realize that the name of this manufacturer represents what they are all about: pure vintage tube tone, with no unnecessary bells and whistles.
