Description

This extremely useful wrench has an easily adjustable tip that will fit any size harp tuning pin with a square, straight head. Pedal harps, lever harps, even antique harps can all be tuned with the same wrench, making it the ultimate tool for harpists with multiple instruments or for teachers whose students frequently forget to bring their wrenches to lessons! And if you've lost a tuning key and can't find a new one that's the right size, the Universal Wrench will work for you. No more rounding over the pins with tuning keys that don't quite fit or chewing them up with socket wrenches or pliers! Using the same ergonomic handle (made of maple) as our custom harp wrench, the Universal Wrench is comfortable in the hand and works like a charm.

Adjustable range: .160" (4mm) to .236" (6mm)

Please see the Sizing tab for examples of pins that do not work well with this wrench.

Note: We know the price is 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.

Sizing

Adjustable range: .160" (4mm) to .236" (6mm)

This wrench is meant for standard, square-headed harp pins, which go all the way through the neck of the harp and stick out on both sides.

These are some types of pins that are not a good fit with the Universal Wrench:

  • It does not work well on zither pins, which you can identify by their sloping shape (see photo below) and the fact that they stick out on only one side of the harp neck. These are often used on small harps like Harpsicles. Due to the tapered shape, the Universal Wrench will damage the pins over time, and we recommend instead using one of our our hammered dulcimer tuning wrenches or our Duo-Tune Zither.

  • It does not fit pins that have a non-square or flattened head (see photo below)
