![]() ![]() This means that the output jack or the amp never really see or are shorted directly to ground-the pickup is shorted to ground instead. To resolve this problem, simply swap the input to lug 2 and the output to lug 3. Since the volume controls are in parallel and the output of the volume pots is the sweeper, when either of the controls is turned down (applying signal to ground) the sum output (what the output jack and amp "see") is "short-circuited" to ground. Yet, on a Fender Jazz bass, which doesn't have a selector switch, two volume controls somehow allow you to turn the pickups up or down independently, without affecting the output of the other. The volume control for the neck or bridge pickup will turn down the whole guitar-not just its respective pickup. If a guitar has two or more volume controls that are wired in the traditional manner (a Les Paul for example), an interesting thing occurs when the selector switch is in the middle position. Reversed (Jazz Bass) wiring for independent control of volume The "hot" output (sweeper lug 2) pans between the "hot" input (lug 3) and ground (lug 1). Typical wiringÄiagram #4 shows a typical guitar pot. Experiment with different value pots to see which ones work best for you. High frequencies are the first to go to ground therefore a lower value pot will allow more of these frequencies to pass to ground, rather than out to the amp as a part of the guitar's signal. This is because that there is always a certain amount of signal going to ground, even at full volume (10 on the knob). A higher value pot can produce a brighter tone, while lower values can fatten the tone by attenuating some of the high-end frequencies. Generally, 250K pots are used with single-coil pickups, and 500K pots are used with humbuckers. The value of the volume pot used is determined by the guitar's pickup(s) and the preference of the player or builder. If the sweeper is connected to the other end of the resistive strip (10 on the volume knob), then the guitar would be at its maximum volume level. If the sweeper, which is usually the output of a volume control, is connected to the lug that is grounded (zero on the volume knob), then there will be no output. ![]() By sending part of the signal to ground, a volume pot controls the amount of electrical signal the amplifier receives. When wired as a volume control, the pot allows you to vary the amount of electrical current flowing through it. In order to control the volume of an electric guitar, the signal is directed through a pot. View All WOODSTAX - Shop Tonewood by the Piece.View All All Hardware + Parts by Instrument.
