Good Vibrations: Repair and Beyond With Chris Brandt
In my last article I posed a leading question to the readers…
A magnetic pickup on an electric bass (or guitar) can not hear wood resonance yet if you plug it in and stand back and listen you CAN hear wood resonance. How does the pickup do it?
Jonathon M. sent a great answer and it opens up a rich way of better understanding the electric bass. He shared:
“In short, the resonance of the wood dictates how the strings vibrate. The resonant characteristics of the wood cause some frequencies to dampen (zero) and others to resonate (pole). The magnetic pickups only react to the magnetic field vibrations caused by the strings, which is entirely determined by the “pole/zero” characteristics of the wood (and the neck joint, bridge mass/material, nut material, etc.). There’s plenty more physics behind the sound of any instrument, but that’s beyond the scope of this question. Thanks for the great question!”
Jonathon’s answer gets to the idea that there is a circulation between the energy in vibrating strings and the energy in the vibration of all the rest of the bass. This continuous circulation of energy shapes the tonal properties arising from the body, neck, bridge, and other parts as well, but it also sets up the flex characteristics principally of the neck. These flex characteristics can effect how low the action can be adjusted and it varies from bass to bass, even on instruments which appear to be identical. Same model, same wood, same everything, yet they aren’t the same and each has to be adjusted for its own best performance.
The electric bass is a system of great complexity and nuance and over the next few articles I’ll discuss some of these subtle and interesting factors. You could say that the vibration in a bass circulates with all of the other vibration in a bass and this accounts for its complexity. It is a sophisticated system. But all of this complexity is balanced by an elegant simplicity as well. The energy (vibration or resonance) flowing back and forth between the body and strings is totaled up within the string vibration. Here you can think of the strings as a delivery system for carrying the resonance from the body and neck to the pickups. Strings do a lot of multi-tasking, and I’ll discuss this in a future article. The complexity within the cross-resonating body might be comparable to the ripple patterns from raindrops on the surface of a pond but this doesn’t bother the strings a bit. They are happy with all of it and the strings pass this energy to the pickups which are like the front door to the rest of the system. This sophisticated system makes for elegance and simplicity and there is tremendous complexity as well.
Here’s what’s cool. Once the pickup comes into the picture, we cross into a historic revolution within the development of stringed instruments. You see, we now have the emergence of an entirely new pathway to get sound to the human ear! By now we’ve all grown up with electric instruments so it is easy to take them for granted, but if you think about the slow development of musical instruments over many centuries you can begin to see how revolutionary this new technology really is. The power of a bass is no longer confined by the acoustic limitations of the pre-electric instrument and the physical capacity of the person playing it. There are enormous new tonal possibilities and it revolutionizes what is now possible in terms of range extension. This business of range is particularly important for the bass because dropping down into low registers has always been hard to do acoustically. This is a big subject and I’ll discuss it more in a future article.
But beyond all this, there is an even more revolutionary effect and it might not necessarily seem obvious. You see, the sound or energy produced by an amplifier becomes a second source of the energy which enters the bass. The first source of energy is the bass player playing the strings but the second source of energy is the sound from the speakers inundating the bass itself. It re-circulates energy back into the bass almost as a form of arco, arco in the sense that a violin bow can indefinitely keep a flow of energy going into the violin. So I think of the energy from amplification as an intrinsic component of the electric bass itself and this “second” source of energy is why an electric bass feels as if it physically comes to life when it is plugged in. This too creates something new in the history of stringed instruments.
Knowledge is power and this is the key to appreciating how fantastic the electric bass really is. I hope that interested bass players will find it helpful to picture how energy moves through out the bass and that this now gets us ready to start talking about all sorts of practical questions having to do with set ups and adjustments, repairs and modifications, differences in construction and much else as well. If you have a few questions about repairs or set ups go ahead and send them my way and we’ll get started.

A review of the Joyo Gloam – Sub Octave Fuzz Pedal for Bass
Disclaimer: This pedal was kindly provided by Joyo for the purpose of this review. However, this does not influence our opinions or the content of our reviews. We strive to provide honest, unbiased, and accurate assessments to ensure that our readers receive truthful and helpful information.
Introduction: The Joyo Gloam is a sub-octave fuzz pedal specifically designed for bass players, combining modern sub-octave effects with rich fuzz tones. With two independently controlled circuits, the Gloam aims to provide a versatile range of sounds, from deep, aggressive fuzz to Moog-like synth effects. This review will explore the Gloam’s specifications, controls, and overall performance, highlighting both its strengths and areas for improvement.
Specifications:
- Dimensions: 130 * 110 * 50 mm
- Weight: 403g
- Working Voltage: DC 9V
- Controls: The Joyo Gloam features a comprehensive control set designed to provide bassists with a wide range of tonal options:
- Dry Tone: Adjusts the tone of the clean signal.
- Dry Volume: Controls the volume of the clean signal.
- Sub Octave Volume: Adjusts the volume of the sub octave signal.
- Gain: Controls the amount of gain in the fuzz circuit.
- Fuzz: Adjusts the intensity of the fuzz effect.
- Bass: Controls the bass frequencies in the fuzz circuit.
- Treble: Adjusts the treble frequencies in the fuzz circuit.
- Fuzz Mode Switch: Switches between two different fuzz modes.
- Dry Tone Frequency Switch: Selects between two different frequency points for the dry tone.
Performance: The Joyo Gloam excels in its dual-circuit design, offering both a sub octave and a fuzz channel that can be controlled individually. However, it’s important to note that the octaver cannot be used without the fuzz circuit activated; the only way to solo the octaver is by turning down the fuzz while both channels are engaged.
Fuzz Circuit: The fuzz circuit includes standard controls such as gain, volume, bass, and treble, along with a fuzz mode switch that toggles between two distinct fuzz modes. While one of the fuzz modes is highly usable and delivers a rich, aggressive tone, the other mode falls short and is less practical for most applications.
Octaver Circuit: The octaver circuit features controls for sub octave volume, clean volume, and clean tone, along with a dry tone frequency switch that provides two different frequency options. This allows for significant tonal versatility, enabling bassists to fine-tune their sound to match their preferences. Despite its limitation of being tied to the fuzz circuit, the octaver produces a deep, balanced sound that stands out.
Combined Effect: When used together, the fuzz and octaver circuits create a wide range of sounds, from classic, aggressive fuzz to synth-like tones reminiscent of a Moog synthesizer. This combination makes the Gloam a powerful tool for bassists seeking to experiment with their sound and achieve unique, textured tones.
Pros:
- Versatile Controls: Extensive control options for both fuzz and octaver circuits.
- Rich Tones: Delivers deep, aggressive fuzz and balanced octaver sounds.
- Sturdy Construction: Durable build quality ensures reliability.
- Wide Range of Sounds: Capable of producing everything from classic fuzz to synth-like effects.
Cons:
- Unusable Fuzz Mode: One of the fuzz modes is less practical.
- Dependent Octaver: Octaver cannot be used independently of the fuzz circuit.
Conclusion: In conclusion, the Joyo Gloam sub-octave fuzz pedal offers a versatile and powerful option for bassists looking to expand their tonal palette. Despite some flaws, the Gloam delivers impressive sounds and flexibility. Its combination of rich fuzz and deep octaver tones, coupled with a sturdy construction, makes it a valuable addition to any bassist’s pedalboard. For those seeking a modern bass distortion with the added depth of sub-octave effects, the Joyo Gloam is a compelling choice for a very compelling price.
