Guitar making is like cooking – change one ingredient and the food transforms into something completely else. The Duke Supersonic has its own unique voice, primitive power and punch, aggressive lower mids – completely different from its big brother with carved top. It’s a first class no-nonsense guitar that can take a lot of beating without folding.

The Duke Supersonic has existed in our model selection for a long time, and evolved through many steps to what it is today. Even the name has changed from Sonic to Twinsonic, and recently to Supersonic. This guitar is in fact the forefather of the Unicorn Supersonic – even though you might think it’s been the other way around.

We offer the unique Bare Bone finish now also for the Duke Supersonic, as well as the innovative wraparound bridge anchoring system I call the Lock-Thru-Body bushings. And as with every one of my guitars, you have a plethora of options to customise the Supersonic to fit perfectly to your taste. Check out the specifications section to learn more.


For your inspiration – here are some Duke Supersonic guitars we’ve made. When you plan ordering your own custom guitar from me, feel free to ask me about any type of custom options!
