Nearly £3,500 has been raised so far by 130 supporters, with just a few days left to enter.
The guitar has been manufactured by Établle who gave a lot of thought to the materials to use. The top is made from Hawaiian Koa and the main body is English walnut. Ziricote was been selected for the neck and fretboard which has a distinctive appearance and excellent sound.
The Guernsey Mind logo on the fretboard has been inlaid with crushed sapphire, which is believed tohave properties of protection, healing and calming.
These materials have been combined with high quality hardware with a Schaller Hannes bridge and custom finished Sperzel Trim Lok tuners.
