"Many Rickenbacker guitars and basses come with a fifth control knob which provides extra tone adjustment capabilities. It can be used to adjust the volume of the bass pickup in relation to a preselected treble pickup lead volume setting, it can be initially set at the tone which will be most often used, or it can function as an equalization control between bass and treble. To use the fifth knob as a bass pickup volume equalizer, first place both volume and both tone controls on the instrument at their maximum clockwise positions. Then, move the pickup selector to the treble position and set the amplifier to the desired lead sound. Now, switch the pickup selector to the bass pick up. The fifth tone knob can now be adjusted in order to bring the rhythm sound to a volume compatible with the already selected lead sound volume.
To use the fifth knob in a set position, first place both volume controls and both tone controls on the instrument at their maximum clockwise positions, and move the pickup selector to the center position. Now, adjust the amplifier, by setting the gain controls at the desired volume and the bass and the treble controls at their maximum positions. Finally, adjust the fine tone selection knob on the instrument until the tone which will be used most frequently is reached, and leave it in that position. After the small knob has been set, the pickup selector may be moved down for maximum treble or up for maximum bass. The variable volume and tone controls on either the amplifier or the instrument can now be moved to the desired volume and tone settings.
To use the fifth knob as an equalization control, first place both volume controls and the treble tone control on the instrument at their maximum clockwise positions, and move the pickup selector to the center position. Move the bass tone control on the instrument to its maximum counterclockwise positions, and set the volume and tone controls on the amplifier to their desired positions. Now, with the instrument's treble up full and the bass at its minimum, the fine tone selection knob can be used as a tone equalizer, moving the instrument through the entire tonal range without adjusting the amplifier."
