." Wood, being a naturally occurring material, is prone to variations in density and flexibility. This, coupled with the high stresses created by stretching steel strings across them lengthwise, makes wood necks prone to certain unpredictable and undesirable qualities. Among these are twisting, incorrect "bowing" (either too pronounced or too subtle), and "dead spots," or areas on the neck where notes are quieter or more indistinct compared to other areas. Non-traditional neck materials such as carbon fiber and aluminum are attempts to correct these issues by replacing wood with lighter, stiffer components.
Gould was inspired to experiment with non-traditional materials after attending a 1974 Grateful Dead

After being passed over by his employers in the aerospace industry, the project of creating hollow, carbon fiber bass necks was brought to fruition by Gould and Alembic, who built a bass with a prototype neck and displayed it at a trade show in 1977. Immediately after the trade show, the bass was purchased by Fleetwood Mac
