Well this is my biggest build so far. The Guitar Bow. You can turn your guitar into a cello or violin as demonstrated by Chris Gowing of Saving Strike a great band from Hastings you must check them out! You have Attack, Decay, Harmony, Blend and Sense controls to help you get that unique sound. Designed to work with all types of guitar pick ups. Completely crafted by hand including the enlosure and using some components which are as rare as hens teeth! I will probably only build these to order. Thanks for looking!
