My optical pickups, use an infra- red or matched pair of optical sender and receivers, that follow  the movement of the vibrating string.  This method for pickups, offer no mechanical distortion nor magnetic drag to the strings.

The "optical shadow" is the result of the senders and  receivers signal. Since it is the shadow of the string that is amplified, any type of string may be used; nylon, steel, bronze, gut, etc.

The signal output is full frequency audio sound, from below and well above human hearing, and only the bridge pickup is required.
