The top of the line instrument from GString Ukuleles. These ukuleles are built by Derek himself and number less than 12 per year. Each one of his creations are individually signed and numbered. All of the artists that are sponsored by GString play an ukulele made by Derek. If you would like an ukulele built by Derek, contact us and ask for the Signature Series ukuleles. Derek will personally talk with you and design the ukulele that you have always wanted. Derek also creates one-off customs based on his own imagination, so look for these in finer music stores near you!
