"This TB1000A features a double-cutaway koa body with a natural finish that is connected to the Reynolds T6061 aluminum neck with four wood screws. In 1977, the company reworked its body-chambering technique to remove some aluminum from the top instead of the side. The aluminum inside this guitarуs wood body was machined to create a U-shaped channel that provided a more rigid structure and also lightened the guitar a bit. However, this aluminum-wood hybrid still tops the scale at almost 10 pounds. Other features include a rosewood fretboard with large, pearl-dot inlays, original custom humbuckers with engraved chrome covers, and original hardware, tuners, pots, and capacitors."
