Updates: We have just migrated our website and have some details to clean up, so please pardon the mess! We’d also like to ask for your patience if we are slower than usual to respond to orders, emails, and phone calls. We are still dealing with the challenges of operating a manufacturing business safely during COVID, and we are working with limited staff capacity. Thank you!
Please read the Sizing info below if you have a non-Dusty harp!
Note: We know the price of the Universal model seems high, and it's because we need to have the adjustable shaft custom-milled for us. In the past, we were able to buy an off-the-shelf product and modify it to work with the full range of harp tuning pin sizes, but it's no longer possible to find that product in the quality we need. We considered discontinuing the Universal Wrench altogether, but we know it can be a lifesaver in specific situations, so we opted to go with the custom part, even though it meant raising the price.
Tuning a harp typically requires an electronic tuner, a clip-on tuner pickup and a tuning wrench, as well as a certain amount of coordination. We do a lot of harp tuning at Dusty Strings and this awkward process was begging for an improvement. We've now combined our harp tuning wrench with the Snark clip-on electronic tuner to make a single handy tuning device, the Dusty Duo-Tune. Now you can pluck a string with one completely free hand while the tuning wrench and electronic tuner are in your other hand picking up the vibrations through the tuning pin, displaying the note on the attached LCD screen, and allowing you to adjust the pin - all at once. No more juggling tuners, wires, clips and wrenches and wishing you had three hands!
Note: The Snark tuner carries a one-year warranty against defects in manufacturing. Should anything happen to yours outside of the warranty, it is possible to replace just the tuner head without buying a whole new Duo-Tune wrench.
There are four models of the Dusty Duo-Tune to fit different sizes of harp tuning pins. The size that each wrench fits is engraved on the handle, but we realize most people don't have calipers readily available to measure their tuning pins. So here is a list (to the best of our knowledge) of harp makers and the size of wrench we expect will fit their harps. Unfortunately, we can't make any guarantees, and current harps may not necessarily have the same tuning pins as older harps by the same maker. We do our best to add to this list as we get more information about pin sizes.
Custom: For tuning pins with a square tip diameter of .176" or 4.5mm. Does not work well on zither pins.
Concert: For tuning pins with a square tip diameter of 3/16" or .188" or 5mm. Does not work well on zither pins.
Universal: Adjusts to fit harp tuning pins with square heads from .160" or 4mm to .236" or 6mm. Does not work well on non-square pins, zither pins, or other pins with tapered heads; please see Sizing tab on our Universal Wrench page for more details.
Zither: Fits harps that have zither pins instead of through-pins. You can tell you have zither pins if your tuning wrench goes on the same end of the pin as the string, and the pin does not stick out on both sides of the neck.
The zither wrench is designed to be held in your left hand, in order to tune a harp with zither pins in normal playing orientation. If you prefer to turn your harp around so that you can tune with your right hand, this wrench will not work well, as the electronic tuner will be facing away from you.
Please note that the zither wrench needs about 3/8" clearance on the end of the pin in order to seat firmly. If your string coils are closer to the end of the pin than 3/8", the wrench may not go all the way on, and you could have difficulty tuning.
