Since 2020, I have been developing classical guitar models using substantial amounts of carbon fibre in the back, sides and top.
In 2022, I began working on a concept guitar using a carbon fibre double-top, with considerable success. I am still in the prototype stage for this new design, and have incorporated colour into my back and sides (as an option). I'm very happy with the sound and structure, but still feel like the cosmetics are only 90% there, so I am not yet asking full price for these instruments.
What do they sound like? All I should say is that people are surprised at how similar they sound to my wooden instruments (typically my balsa/CF lattice-braced style). Yet still subtly different ... so a side-by-side comparison is more useful. When I get a chance I'll be recruiting some professionals to do side-by-side recordings using the same equipment, player and music for a proper comparison.
Next up (winter 2024-25): Developing a carbon fibre neck.
