Dusty Harp Pickup
Pickup Type

The Dusty Harp Pickup is our answer to the question, "How can I make my harp louder and still have it sound the way I love?" Harps are particularly difficult to amplify because of their long soundboards, and when we spent time testing a bunch of different options, we didn't find anything we were completely satisfied with. We are perfectionists about how our harps sound, and we realized that designing our own harp pickup was the only way to ensure an amplification solution that would meet our standards.

After extensive development and testing, we came up with the Dusty Harp Pickup. Rather than relying on one (or sometimes two) contact points, which can't help but pick up more sound from the notes that are close by and less sound from the notes farther away, our pickup has 4 carefully selected piezo elements spaced along the length of the soundboard. (Three elements in the case of the smaller P10.) This creates a balanced and focused sound throughout the whole range of the harp. The full, rich bass notes blend with the clear mids and highs, providing natural-sounding amplification at any volume level. It's simply the sound of the harp, only bigger!

Although we initially designed the pickup for our own harps, the response was so enthusiastic that we created a kit to allow the pickup to be installed in a wide variety of harps by other makers. We even developed a pedal harp version, and over the years our pickups have been successfully installed in many non-Dusty harps. Harpists and sound technicians alike rave about how easy it is to use and how even and natural the sound is.

The pickup is discreetly mounted inside the soundbox, invisible to the audience. A single jack mounted on the back of the harp makes for "plug and play" ease of use. An instrument cable (not included) connects your harp directly to any amplifier and most PA systems. In most situations a preamplifier is not needed, but if you are playing in situations requiring very high volume, you may want to add one. In addition to boosting the signal, it will give you direct control over your volume and tone. With some amplifiers, a preamp can also sweeten and smooth out your sound.

We can install the Dusty Harp Pickup in any new or existing Dusty Strings harp, and it can also be done by harp owners who are handy with tools or by any instrument repair technician. Installation involves attaching mounting clips to the internal braces or sides of the harp, snapping the cable harness into the clips, gluing the elements in place, and drilling a hole to mount the jack in the back of the harp. There are detailed instructions and a template for placing the elements in Dusty Strings harps. If you have a different type of harp, use the template as a starting point, but it's a good idea to experiment with the element placement to confirm the best-sounding attachment points. The only tool you'll need is a ½-inch brad point drill bit, available at most hardware stores or from us. If you prefer not to drill a hole, you can simply connect to the jack through the bottom soundhole of your harp, or add our Jack Clamp for a secure and removable way to anchor the jack.

Please note that the pickup produces the best possible sound when the elements are super-glued to the back of the soundboard, as specified in the instructions. If you choose to use double-stick tape for a less permanent installation, you will have a challenge getting the volume loud enough, and you will not get the sound quality this pickup is known for. Once the pickup is glued in, it can be removed if desired, although we don't recommend that because it is too easy to damage the elements in the process. In any case, the presence of a high-quality pickup system will enhance the appeal and value of your harp.

If you're curious about the installation process, you can download and read the installation instructions for lever harps (P10, P20, or P25) or for pedal harps.

Specifications

P10 (for 24-30 string lever harps):

  • 24" long
  • Additional 8.5" of lead
  • Minimum soundbox length (internal): 25.5"
  • 3 piezo elements
  • In order to mount the jack in the back of the harp, either by drilling a hole or using the Jack Clamp, the soundbox depth should be a minimum of 4-5". Small lap and therapy harps with shallow soundboxes might require the jack hole to be drilled on the side instead of the back, and the Jack Clamp may not work.

P20 (for most 32-40 string lever harps*) and P25 (for Serrana 34):

  • 28.5" long
  • Additional 7.5" of lead
  • Minimum soundbox length (internal): 30"
  • 4 piezo elements

P30 (for pedal harps and some pedal-harp-styled lever harps*):

  • 34" long
  • Additional 24.5" of lead
  • Minimum soundbox length (internal): 35.5"
  • 4 piezo elements

*Certain large-stature lever harps are built more like pedal harps, with similar heavy construction and high string tension. The Lyon & Healy Prelude and Troubadour, Camac Mademoiselle, and Salvi Ana are good examples. Although they have levers and not pedals, in all other respects they are much closer to a pedal harp in sound and design, and we would recommend the P30 pickup for the best results.

Please also note that these pickups were designed for and have been tested primarily on harps made of wood. If you're hoping to amplify a carbon fiber harp, we would suggest first contacting the harp maker to see what sort of amplification they recommend. Carbon fiber behaves differently than wood does, and our pickup may not be an ideal solution for a carbon fiber harp.

Impedance and Choosing an Amplifier

The Dusty Harp Pickup system utilizes piezo pickups that are "high ohmic," meaning that they operate optimally in a high impedance circuit. Results will be best when the pickup is plugged into an amplifier that has an ultra-high input impedance of about 1 megohm or higher. This will provide a flat and balanced frequency response.

If you plug this pickup into an electric guitar or bass guitar amplifier, you may hear a thin sort of "quacky" bass response and there may be other frequencies that are filtered out. You may not like the sound! This is not the fault of the pickup, but is the result of the mis-match of this ultra-high impedance acoustic pickup with a high impedance electric guitar amplifier.

In short, coupling the Dusty Harp Pickup with an amplifier optimized for acoustic instruments with piezo pickups will give you the best sonic reproduction - the full, rich acoustic sound of your unamplified instrument, only louder!
