Bridge for UBASS conversion based on Bontempi GSW75/N

thingiverse

This bridge is engineered as a seamless addition that preserves the original integrity of Bontempi GSW75/N child guitar's structure. It simply slides into place, filling the existing gap with ease, and can be secured using two small nails, just like bolts, as shown in the accompanying picture. The only modification required to get it up and running is enlarging the holes in the nut to accommodate four thicker strings instead of six smaller ones. Incidentally, the strings used are known as Thundergut from Aquila.
