Regulating Camac Levers

The great thing about Camac levers is that the player can easily regulate them. I rarely attempted to regulate my harp with any other lever, but with the Camacs, I am very confident that I can do it and so can you.

Here are instructions for regulating your harp with Camac Levers.

You will need the following which you can obtain from us for $60.
• 6mm nut driver for use with the lowest strings
• 5mm nut driver for use with the middle strings
• 4mm nut driver for use with the highest strings. Note that this tool has been ground down to fit between the levers of the highest strings. In our tool kit, this has been done for you.
• #8 torx driver (the red one) for use on all the levers where they connect to the neck
•  These instructions.

To regulate your harp, first, connect your harp to a tuner.
Tune the low C, then lever the note and play the C string again as a C#. If the levered C# note registers in the same spot on your tuner as the open note, then move on to the next string (D).

If the levered C# note is flat, use your 6mm nut driver and turn the bridge pin counter clockwise. This will raise the pitch of the levered note. Check the pitch and if it’s still flat, turn the bridge pin a little more.

If the levered C# note is sharp, turn the bridge pin clockwise to lower the pitch of the levered note.
Continue moving up the harp in this manner.

Here are some helpful hints for regulating:
The bridge pins are threaded, so as you turn the bridge pin counter clockwise, the pin twists out from the neck. As you turn the pin clockwise it goes further into the neck.

You will need to turn the bridge pin a larger amount for the lower notes and smaller amount for the highest notes to make a difference in the pitch of the string.

You will need to engage the lever of the very highest strings to access the bridge pin.

If you have to turn the pin so much that the string then is too close to the lever and buzzes on the lever parts recenter the bridge pin approximately to where it was before it buzzed. Then using the torx driver, loosen the screws that hold the lever onto the neck, but don’t remove them; just barely loosen them.
If the levered note was flat, you’ll want to slide the lever down a little bit. If the levered note was sharp, you’ll want to slide the lever up a little bit. Make sure you keep the lever straight up and down.

Tighten the screws just enough to hold the lever to the neck but not so much that you break the screw. Then re-regulate the harp using the other nut driver (4, 5, or 6mm) to adjust the bridge pin and regulate the note.
