The MESA/Boogie® Head-Track™ is a Head + Effects Loop Switcher that enables two amplifier Heads to be used with one set of Effects and Speaker Cabinet.
The Head-Track™ gives you the ability to instantly select between two amplifiers, yet employ the same Speaker Cabinet and Effects setup. It is intended for use near the amplifiers being switched to maintain the shortest Cable lengths, thereby protecting the integrity of your signal, and has a Remote Switch jack so that a simple On/Off MIDI switching function, or Latching Footswitch located on your pedal-board, can control the switching. There is also an on-board Footswitch to switch between the two amps from the unit itself in the rare instance where the Head-Track might be used on the Pedal-Board.
INPUTS from Instrument, Amplifier Effects Loop Sends (2), Effect(s) Output and Amplifier Speaker Outputs (2) along with OUTPUTS to Amplifier Inputs (2), Amplifier Effects Loop Returns (2), Effect(s) Input and the Speaker Cabinet Input (or Load Device) being shared are provided. The Head-Track can be powered by an external 9 Volt DC/200 mA wall-mount power supply (not included).
