Bass guitars come in various shapes, sizes and construction styles – each factoring in to its tone and playability.
4-string bass guitars can play notes as low as E1, giving them 4 full octaves of deep range. 5- and 6-string basses may also be tuned down to B for extended playback capabilities.
Frequency Range
Bass guitars play an indispensable part in most bands. Although their sound may not reach as far, bass guitars fill out the low end of the frequency spectrum and provide structure and shape to other instruments in a band. Furthermore, they allow more experimental sounds that cannot easily be produced elsewhere to come through without difficulty.
Though most bass frequencies lie low on the spectrum, their frequencies do extend into the midrange as well. This is because double-string instruments like bass guitars have two strings played at different octaves: low is played on fret one while high octave occurs two frets up and one string over. As such, each bass can cover four octaves at any given time!
When it comes to EQing a bass guitar, the 200Hz-300Hz frequency spectrum is of key importance in terms of its impact. Mud usually lives here and removing it can help your mix sound clearer – however be careful not to cut too deeply from this range as doing so could make the track sound boxy or hollow.
Notability in bass’s low-mids (800Hz and 1kHz). This area should be carefully monitored because bass guitar adds punchiness when played distorted; when adding this range with wide, gentle curves – this ensures you won’t push it too far into mid-range which could potentially sound nasal and muffled.
Sub bass frequency range should also be addressed; typically around 60Hz. Here resides your deepest bass sounds; just keep in mind that other instruments in your mix may also contribute a low frequency content of their own. Too much sub bass can sound muddy and boxy while too little will leave it sounding hollow and thin.
With so many frequencies to consider when EQing your bass guitar, it’s crucial that you understand which ones should be highlighted and reduced when creating its tone. By tailoring its sound precisely to complement the kick drum without overshadowing it, sculpting your tone can ensure it sits perfectly within its place in the mix without overshadowing anything.
Bass EQ
As with anything, tone starts with the player. Where they place their hand or how they pluck the bass will have an immense effect on its sound – for instance, moving closer to the bridge will produce an upbeat 1970s funk sound while moving further up neck will result in richer, fuller tones. Furthermore, room acoustics have an enormous effect on how a bass sounds in that environment.
Equalization (EQ) can help you achieve a more desirable sound, but proper application requires knowledge of its proper usage. Most equalizers include frequency bands which allow you to sculpt your bass guitar tone by either increasing or decreasing specific frequencies.
There are four approximate areas where most bass EQ adjustments should take place:
20Hz-60Hz: This range is the lowest frequency range for bass guitar, providing a full and deep sound. When overemphasized it can become muddy while when cut too much it will sound thin.
200-300Hz: Muddiness thrives within this frequency range, making it challenging to mix. Too much muddiness may make bass and snare drum sound hollow or boxy while not enough will lead to clarity issues with your track.
500 to 1000Hz: Your bass’s punchiness resides here, so boosting this range can add thickness to the low mids for a full bass sound.
2-5kHz: This area of the bass’s attack falls between 2-5 kHz and can be used to emphasize pick and finger strikes from bassists, or bring out clanks for more aggressive tone when amplified with an increased Q value.
4-6kHz: Raising this range brings out the metallic sound of strings, helping your bass stand out in a mix. It may also serve to highlight transients for players who don’t play aggressively enough.
Midrange EQ
Bass guitars produce an array of sounds ranging from the simple amplification of string sounds to more complex electronic sounds found in heavy metal music. Their sound can also be altered depending on how the instrument is played; whether using a pick, fingernails, or both to play it can create different sounds by striking or plucking strings, or slapping them.
Midrange frequencies are key when it comes to EQing a bass guitar, as this range will share space with vocals, percussion and drums in your mix. To cut through all this noise more effectively and balance out competing frequencies more easily. By increasing or decreasing bass when necessary and cutting when possible.
Increasing attack in a bass by increasing frequency between 800Hz to 1kHz can be useful when playing with distortion, giving it more of a plucked sound that cuts through dense mixes more effectively. Furthermore, adding brightness with a small boost from 1kHz-2kHz may add crispness that helps it cut through dense mixes more effectively.
Though these charts can help teach us what certain frequencies do, it is essential not to rely on them too heavily when mixing. Each track and bass guitar has different characteristics so a generic chart won’t do. Instead, make it your goal to memorize these frequencies so that adjustments can be made faster and more accurately.
As a rule of thumb, it’s best to cut frequencies between 40Hz and 80Hz to minimize boominess and allow bass guitars to cut through small speakers more easily. Midrange boosts may also help create fuller-sounding basses; boosting between 250Hz and 300Hz can add snap or remove string slap noise, while increasing brightness between 4KHz and 6KHz will make vocals sharper and add shine to cymbals and percussion instruments.
High Frequency EQ
Bass guitars can feature many tuning options, with popular examples including BEAD and D-G-C-F tunings giving deeper range than an electric guitar. Basses also typically include onboard electronics that allow the player to amplify and regulate string frequencies.
High frequencies are used to add clarity and brightness to soundscapes, and bassists may utilize this area of the spectrum for shimmering effects. When working with this range of frequency spectrum it is typically best to cut back rather than boost in this region; otherwise unnatural sounds may occur and reduce headroom available to mixers.
Keep in mind when EQing any instrument, it is usually best to make only subtle adjustments – no more than a few dB either way – since drastic EQ changes will sound unnatural and also consume headroom in a track, making other elements of it hard to hear clearly.
As its name implies, a bass guitar is designed to produce bass lines and rhythm parts. While most commonly played with a kick drum, solo players or ensemble members also often utilize this type of instrument. Modern bass guitars typically employ magnetic pickups which pick up vibrations of metal strings converted to electrical signals amplified and played through speakers; other options may also include piezoelectric pickups which produce mechanical vibration of strings converted to electrical signals for playback through speakers.
As well as its electronics, there are other key aspects of a bass to consider when purchasing one. Most importantly is how well it plays for you – try several out before making your choice! Many stores have bass demonstration areas where you can try out various basses before deciding. Bring along an amplifier so you can compare its sound against what is expected by its new owner.
