Fuzz bass, also called "bass overdrive" or "bass distortion", is a style of playing the electric bass or modifying its signal that produces a buzzy, distorted, overdriven sound, which the name implies in an onomatopoetic fashion. Overdriving a bass signal significantly changes the timbre, adds higher overtones (harmonics), increases the sustain, and, if the gain is turned up high enough, creates a "breaking up" sound characterized by a growling, buzzy tone.
One of the earliest examples may be the 1961 Marty Robbins Country and Western song "Don't Worry." By the mid- to late-1960s, a number of bands began to list "fuzz bass" in addition to "electric bass" on their album credits. Two well-known examples are the Beatles' 1965 song "Think for Yourself" (from Rubber Soul), which marked the first instance of a bass guitar being recorded through a distortion unit, and the 1966 Rolling Stones song "Under My Thumb". Album or performance credits for fuzz bass can be found from every decade since then (see examples below).
Fuzz bass can be produced by overloading a bass amp's tube or transistor preamplifier, by using a bass fuzz or bass overdrive effect pedal, or for the most powerful effect, by combining both approaches. In the 1960s and early 1970s fuzz bass was associated with the psychedelic music (e.g., Edgar Broughton Band), progressive rock (e.g., Genesis), and psychedelic soul/funk (e.g., Sly and the Family Stone) styles, and it tended to be a "warmer", "smoother", and "softer" overdrive-type sound caused by soft, symmetrical clipping of the audio signal that "round[ed] off the signal peaks rather than razor-slicing" them and filtered out the harsher high harmonics.
In the 1980s and 1990s, overdriven bass tended to be associated with hardcore punk (e.g., Stormtroopers of Death), death metal (e.g., Mortician), grindcore (e.g., Napalm Death) and Industrial bands (e.g., Ministry), and the tone tended to be heavier, more metallic and more grinding. This is achieved by hard clipping of the bass signal, which leaves in "harsher high harmonics that can result in sounds that are heard as jagged and spiky." In the 1990s and 2000s, fuzz bass was also used by indie and alternative rock bands, with a notable example being Muse. In the 2010s, it is also used by hard rock bands, such as Royal Blood.
In the context of electric guitars, the terms "distortion", "overdrive" and "fuzz" are often used interchangeably, but they have subtle differences in meaning. Overdrive effects are the mildest of the three, producing "warm" natural overtones at quieter volumes and harsher distortion as gain is increased. The best quality overdrive effects respond to how hard the bassist picks or plucks the bass, producing little or no distortion when the instrument is played quietly, but gradually adding overdrive as the instrument is played harder. A "distortion" effect produces approximately the same amount of distortion at any volume, and its sound alterations are much more pronounced and intense. A fuzzbox (or "fuzz box”) alters an audio signal until it is nearly a square wave and adds complex overtones by way of a frequency multiplier.
A fuzz bass sound can be created by turning up the volume of a tube amp or transistor amp to the point that preamplifier tube (or transistor preamp) clipping" occurs. In practice, when a bass amp is "cranked" to its maximum volume, the fuzz tone will also include some power amplifier clipping. While some musicians seek out the additional "grit" provided by power amp clipping, audio engineers and bass technicians recommend avoiding power amp clipping, as it can blow speakers. In the 2010s, a number of specialized fuzz bass pedal effects are sold, ranging from mass-produced commercial models to expensive boutique pedals. Fuzz bass can also be produced by using an electric guitar fuzz, distortion or overdrive pedal. The downside of using a pedal designed for the electric guitar is that the lower-end bass tone is mostly lost when the signal is heavily clipped.
Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping may cause it to output power in excess of its published ratings. Clipping is a non-linear process that produces frequencies not originally present in the audio signal.
These frequencies can either be "harmonic", meaning they are whole number multiples of the signal's original frequencies, or "inharmonic", meaning dissonant odd-order overtones. Harmonic distortion produces harmonically related overtones while intermodulation distortion produces inharmonic overtones. "Soft clipping" gradually flattens the peaks of a signal and de-emphasizes higher odd harmonics. "Hard clipping" flattens peaks abruptly, resulting in harsh-sounding, high amplitude odd harmonics.
Since the late 1980s, manufacturers have been producing bass overdrive pedals specifically designed for the electric bass, and in many cases they found a way to keep the low fundamental pitch in along with the buzzy overdrive tone. One early model was the Ibanez "Bass Stack" bass overdrive pedal, which was sold in the late 1980s.
|Napalm Death live in Germany, 1987, the second song is half-way through the clip at 4 minutes, 37 seconds has a buzz-saw type heavy bass distortion, from YouTube, authorized by Earache Records.|
1980s grindcore groups, such as Napalm Death in the sound clip to the right, used a very heavy, distorted bass tone that resembles the sound of a grinding buzz saw.
The simplest fuzz bass pedals have knobs for controlling the volume level, the tone, and the fuzz or overdrive effect. More complex pedals have different distortion effects (e.g., overdrive and fuzz), gates to trigger the volume at which sounds will get overdriven, mixers to mix the natural and fuzzed sound in the player's desired proportions, and multiple band equalizers (typically for low and high frequencies). Boutique fuzz bass pedals even have unusual effects such as a "starve" effect, which mimics the distortion sound a pedal gives with a dying battery, a diode selector (either silicon or germanium) for selecting the transistor overdrive tone, and an octave selector (above or below the pitch being played).
While fuzz bass pedals are most commonly used by bass players, some electric guitar players use bass overdrive units. Buzz Osborne, electric guitarist from the Melvins, uses a BOSS Bass Overdrive ODB-3 pedal.
Standard overdrive effects for bass include:
- The AGRO bass overdrive is produced by Aguilar Amplification. The manufacturer claims that the pedal is "based on the saturation channel of Aguilar's celebrated AG 500 bass head" and that it can produce "everything from warm, tube-like overdrive to full on distortion" and all the "grind you need without sucking out your low end." It has a saturation (overdrive) knob, a contour knob, a presence knob, and an output knob.
