Here is a recent build from my shop, it is a customized version of the "Road Kill" budget model. The owner of this one wanted a full length 5th string which required a custom Minstrel style headstock to accommodate the added tunning peg. It features the Bubinga wood tone ring and rim cap, Dobson style heel and rosewood fretboard and overlay.
I love it when a customer challenges me to build something new! Although the concept for a long 5th has been around for a very long time, it's certainly something you don't see often these days.
