Abstract: A stringed instrument, such as a guitar is provided. The stringed instrument may include a tuning system in which harmonic and pitch tuning are simultaneously obtained. A bridge assembly is provided on the stringed instrument which includes a force conversion assembly capable of converting nonlongitudinal forces into longitudinal forces such that selective adjustment of a tuning knob or similar control by a user results in slidable movement of saddle members.
Abstract: A constant current source is connected to a first node that connects on the one hand to a predetermined potential via a first switching transistor with a control electrode thereof connected to a signal input terminal, a second node, and a resistive conduction member, and on the other hand to a current output terminal via a second switching transistor with a control electrode thereof connected to the second node to constitute a current switching circuit operable without an external reference bias and with a reduced number of components.
