Gordon Branch's Airtube V is constructed of aircraft-grade aluminum tubing. Cut to different lengths, the pairs of tubes offer varying resonance and sustain, similar to wind chimes. Reinforced with a carbon-fiber shell, the mahogany neck has a Sitka spruce core, titanium truss rod, ebony fretboard, and stainless steel frets. The guitar features active EMG humbuckers, dual tone and volume knobs, and a 3-way switch.
