Atrum Kithara Unique Instruments

Located in our home in NE Portland, Oregon, we are a small shop building, selling, and repairing guitars and other instruments.


Brent Furstner is a graduate of Minnesota State Technical College SE Tech's Guitar Building and Repair program, and has been working on instruments for decades.


Atrum is Latin for dark, ugly, monstrous.

Kithara is one of the first plucked string instruments from Greece and Latin for guitar.


You can currently find a few of our instruments through our instagram, at markets we attend, or contact us at to schedule an appointment.
