These attachable super-trebles are exquisitely built by Luke Brunner in Switzerland. They attach to any guitar with elastic straps and a covered bar that hugs the back of the guitar. Each comes with a built-in K&K pickup, carrying case, and string-changing tool. You may contact me directly to choose from the instruments I have remaining in stock (in photo: Bear claw or walnut), and for payment methods that don’t have a merchant fee such as paypal to my personal account or check. The price may vary slightly more or less from the amount listed depending on shipping options and merch fee if any. If you are outside of the USA, please order from Luke Brunner directly at Brunner-Guitars.com.
