Problematic bass guitar pickups can be frustrating and challenging to work around, but it is certainly possible to address them.
Make sure that the pickups are undamaged. Also check your wiring system. Any loose wires could cause your pickup to misfire and make its malfunction apparent.
Damaged Pickups
Pickups are an integral component of any guitar. They convert string vibrations to electrical signals that allow control over its tone and volume; however, they are vulnerable to damage that could create serious issues if left unchecked.
There are various ways in which your pickup can become damaged, the most prevalent being an improper wiring connection or connection flaw.
An improper connection or wire can impede with the operation of your bass’s pickup, leading it to become inoperable and ultimately fail. You can test for this by taking several measures including unplugging it from its instrument and placing a multimeter near its jack.
Connect two multimeter probes (one red and one black) to the wires on your pickup. Set the meter to Ohm 0.
Magnet failure is another frequent source of pickup failure, often brought on by external magnetic fields that affect their strength.
Alternately, the magnet may have experienced internal breakdown due to insulation fatigue – this condition could negatively impact DC resistance of your pickup.
If your bass’s output has faded or become warmer due to your pickup, replacing its magnet could restore performance and get it working again.
Purchase a magnet that perfectly complements the size and shape of your electric guitar, made from copper or brass for optimal results and powerful output.
At the end of the day, it’s wise to ensure your pickup has sufficient insulation. Doing this can prevent its coil from degenerating prematurely and improve overall performance of your pickup.
Avoid touching your guitar’s pickups too frequently as this could leave scratches on their surface, negatively impacting performance and tone, as well as altering their polarity to compromise functionality.
Loose Wiring or Connections
One of the primary factors contributing to bass guitar pickups not working properly is wiring or connections issues. These connections play an essential role in translating vibration from metal strings into an electric signal; if these connections are made improperly, your bass could sound bad and may not deliver on its desired tone.
In most instances, you can resolve a bass pickup not working issue by replacing or connecting it to another point on your instrument. If you don’t feel confident doing this yourself or lack the necessary tools for doing it successfully, bringing your instrument to an experienced technician might be your best bet.
First, ensure the wires are connected properly to the screw terminals on your pickup. If they’re not wrapped clockwise around them, they could become loose and cause your bass to sound bad. Furthermore, inspect whether any connections have become corroded so as to restore them through resoldering.
Use a multimeter to check the wiring on your bass by measuring resistance; if reading is either zero or L this indicates an open circuit due to something such as bent wiring or improper soldering.
Wiggle the wires to test them further and listen for any static or disruption to your output signal – this can help determine whether it’s the wiring itself that’s at fault or something else amiss with the amp itself.
If your cable has become loosely attached, it could damage the output jack, leading to it malfunctioning and potentially cutting in and out when connected to an amplifier. In order to restore optimal operation of your bass guitar, unplug and tighten its connection before trying to reconnect it.
Loose electrical connections can be dangerous, even leading to fires. This occurs when electrical wires come into contact with metal components that heat up, creating an electrical short. Therefore, it’s essential that all devices and appliances you regularly use be regularly checked for electrical connections that might become loose.
Badly Adjusted Pickups
Many bassists don’t realize it, but pickups can actually move when playing their instrument – a perfectly normal process that often indicates something is amiss with its pickups.
One of the primary causes of bass pickups not working properly is due to improperly adjusted pickups, which can be caused by various factors but usually is easily remedied.
Pickups should be adjusted properly so they produce a strong magnetic field to produce the bass sound you desire. This can be accomplished by turning appropriate screws either side of the pickup clockwise to lower or counter-clockwise to bring closer.
Most manufacturers recommend setting your J-Bass no closer than 5/64″, and P-Bass pickups no closer than 6/64″, however you may also choose to adjust other pickups accordingly for optimal sound. It is wise to follow these guidelines for best results.
Poorly adjusted pickups may also interfere with string vibration when you play, leading to fret buzz and reduce sustain.
Quickly determine whether your pickups are set too high by holding down the lowest E string at its highest fret and hearing a warbling or quacking tone when holding down this string – this indicates your pickups may be too high.
To properly adjust your bass pickups, start by taking measurements with a precision ruler or calipers. This will help ensure that you adjust them at an ideal height without ending up with an undesirable setup later. It is also wise to take measurements on both sides of each pickup so as to ensure even distribution between bass and treble pickups.
Old Pickups
Guitar pickups are delicate devices that can easily become damaged if handled incorrectly or exposed to moisture or heat, or oxidization which results in them losing tone and effectiveness over time.
There are multiple methods you can use to assess whether a bass’s pickups require replacement: performing a magnetic polarity test, visually inspecting them and listening through an amplifier are just a few of them.
Changing magnetic polarity could cause your pickup not to align correctly with the strings, leading to hum, interference, or even sound cutting out when playing. If this is occurring frequently when playing, one or more pickups likely need replacing immediately.
By using a small compass, it’s easy to check the magnetic polarity of pickups and ensure they are properly wired – especially important if using a humbucker pickup.
A compass needle should always point towards magnets of opposite polarity; otherwise, replacement pickups will likely be necessary.
Another method of testing bass pickups is by measuring their DC resistance. Single-coil pickups typically measure between 5.5 to 6.5 KOhms while humbucking pickups can reach 20K ohms.
Old pickups on a bass guitar can have an adverse impact on its sound; as such, upgrading them every few years is always recommended for optimal results.
Switching up the pickups of your bass guitar can be an inexpensive and simple way to improve its sound and increase versatility, giving you access to different sounds.
There is a wide selection of pickup types and models to choose from when selecting a bass pickup, making it important to find one that best matches your bass’s sound. Experimentation will help find what works for you – and will result in the optimal bass tone possible!
