Bridge construction, whether in the context of musical instruments or civil engineering, demands innovation, reliability, and performance. Among the various technologies developed to enhance the durability and tonal quality of stringed instruments, the Breedlove Truss System stands out as a revolutionary approach. This article delves deep into the Breedlove Truss System, exploring its origins, design, advantages, and why it has become a preferred choice for both luthiers and musicians. By the end, you'll understand not only the technical brilliance behind this system but also its practical benefits and long-term value.
The Breedlove Truss System is a specialized internal support mechanism primarily used in Breedlove guitars. Unlike traditional bracing methods, this system employs a cantilevered truss—a wooden dowel or rod anchored from the bridge block to the tail block inside the guitar body. Its main function is to counterbalance the immense string tension exerted at the bridge, which can reach up to 230 pounds[5][1]. By redistributing this force, the truss system allows the guitar's soundboard (top) to vibrate more freely, enhancing tone, sustain, and structural integrity[2][4][7].
The concept behind the Breedlove Truss System originated from the need to address two persistent issues in acoustic guitar design:
- Excessive string tension causing top deformation or "bridge belly"
- The challenge of balancing structural stability with optimal soundboard resonance
Traditional guitars often relied on heavy bracing and thicker tops to withstand string tension, which, while effective for durability, compromised the instrument's ability to produce rich, dynamic tones[5][3]. Breedlove's innovative approach, inspired by the JLD Bridge Doctor, sought to resolve these issues by introducing a truss system that supports the bridge from beneath, distributing tension more efficiently and allowing for thinner, graduated tops[4][7].
The Breedlove Truss System consists of three main components:
- Main Block: Mounted directly beneath the bridge inside the guitar.
- Dowel or Rod: Extends from the bridge block to the tail block, acting as a cantilevered support.
- Adjustment Bolt (Worm Screw): Allows fine-tuning of the truss tension[1][6][7].
When the guitar is strung, the truss system counteracts the upward pull of the strings by pulling downward on the underside of the bridge. This reduces the load on the soundboard, enabling it to vibrate more freely and evenly. The result is a guitar that maintains its shape and action over time, with improved tonal qualities and reduced risk of structural damage[5][4][6].
By counterbalancing string tension, the Breedlove Truss System prevents the top from warping or developing a "belly" behind the bridge—a common issue in traditional acoustic guitars. This ensures the guitar retains its optimal shape and playability for decades[5][1][7].
The system allows for the use of thinner, graduated tops and lighter bracing, which means the soundboard can resonate more freely. This results in:
- Greater sustain and resonance
- Enhanced overtones and harmonic complexity
- Well-balanced tone across all strings[4][5][2]
Because the truss system maintains the structural integrity of the guitar, the string action (height) remains consistent over time. Players experience reliable playability without the need for frequent adjustments[1][7].
Once properly set at the factory, the Breedlove Truss System requires minimal adjustment. Occasional checks are recommended, especially if changing string gauges or in cases of significant humidity changes, but overall maintenance is low[1][6][7].
Breedlove pairs the truss system with other innovations, such as:
- Pinless Bridge: Easier string changes and direct energy transfer from strings to the soundboard[2][4].
- Graduated Top Thickness: Thinner on the bass side, thicker on the treble side for optimal resonance and balance[4][3].
- Scalloped Bracing: Further enhances the guitar's ability to vibrate and project sound[2][3].
| Feature | Breedlove Truss System | Traditional Bracing |
|---|---|---|
| Structural Support | Cantilevered truss, redistributes bridge tension | Heavy X or ladder bracing under the top |
| Impact on Top Vibration | Allows freer vibration, thinner top | Restricts vibration, requires thicker top |
| Tonal Qualities | Enhanced sustain, resonance, and balance | Often less sustain, more muted overtones |
| Maintenance | Minimal, periodic checks | May require repairs for top deformation |
| Longevity | Maintains shape and action for decades | More prone to "bridge belly" or warping |
The Breedlove Truss System is featured in most Breedlove Concert, Auditorium, acoustic bass, and 12-string models. However, it is not used in certain series, such as the Oregon, USA Series, Jumbos, Dreadnoughts, Concertos, and Parlor guitars[1][7]. This selective application allows Breedlove to tailor their instruments for specific tonal and structural goals.
Each Breedlove guitar equipped with the truss system is carefully adjusted at the factory. The dowel should feel snug but able to spin with a touch of resistance when checked inside the guitar body[1][7].
If adjustment is necessary (e.g., after changing string gauges or experiencing significant humidity shifts), it involves:
1. Loosening or removing the strings.
2. Reaching inside the guitar to check the dowel for play or resistance.
3. Using the appropriate Allen wrench to tighten (clockwise) or loosen (counterclockwise) the adjustment bolt in small increments.
4. Ensuring the dowel is snug but not overly tight or loose[1][7][6].
Caution: Incorrect adjustment can lead to costly repairs. If unsure, consult a qualified technician[6][1].
The Breedlove Truss System is engineered to withstand the rigors of string tension over the lifetime of the instrument. By preventing deformation and maintaining structural integrity, it ensures the guitar remains playable and sonically vibrant for years[5][1][4].
Musicians and reviewers consistently praise Breedlove guitars for their "complex sustain," "bloom of tone," and "well-balanced voice." These qualities are direct results of the truss system's ability to free the soundboard from excessive tension while maintaining strength[4][5][2].
Breedlove's approach is a testament to forward-thinking luthiery. By combining the truss system with other design innovations, they have set a new standard for what acoustic guitars can achieve in terms of both sound and reliability[4][2][3].
With factory setup and rare need for adjustment, the truss system offers peace of mind for players who want to focus on making music, not on constant maintenance[1][7][6].
Guitars equipped with the Breedlove Truss System offer exceptional value, retaining their tone and playability over time, which translates to a better long-term investment for musicians and collectors alike[4][5].
Many professional musicians and guitar technicians have noted the tangible benefits of the Breedlove Truss System. Guitars equipped with this system are described as having:
"A lively, brilliant, and rich sound, with warmth, clarity, and character. The care and love in the construction are evident in every note."[4]
This feedback underscores the system's effectiveness in delivering both structural and sonic excellence.
While the Breedlove Truss System offers numerous advantages, there are some considerations to keep in mind:
- Not Universal: The system is not used in all Breedlove models, so players seeking a specific tonal or structural characteristic may need to select accordingly[1][7].
- Adjustment Sensitivity: Incorrect adjustment can potentially damage the instrument, so expertise or professional assistance is recommended for maintenance[6][1].
- Not a Substitute for Proper Humidity Control: The truss system cannot compensate for extreme over- or under-humidification, which can still affect the guitar's wood and playability[1][7].
The Breedlove Truss System represents a significant advancement in acoustic guitar construction, blending innovative engineering with a deep understanding of musical artistry. By effectively counterbalancing string tension, it delivers unparalleled structural stability, enhanced tonal quality, and consistent playability. For musicians seeking an instrument that will stand the test of time—both in sound and durability—the Breedlove Truss System is a compelling choice.
Whether you are a professional performer, a hobbyist, or a collector, choosing a guitar with the Breedlove Truss System ensures you are investing in an instrument designed for excellence. Its unique combination of technical sophistication and musicality sets it apart in a crowded field, making it a benchmark for modern acoustic guitar design.
The primary function is to counterbalance the string tension at the bridge, allowing the soundboard to vibrate more freely while maintaining structural stability. This results in enhanced sustain, resonance, and long-term durability of the instrument[1][5][7].
No, the system is factory-adjusted and typically requires very little attention. However, it should be checked periodically, especially after changing string gauges or experiencing significant humidity changes. If adjustment is needed, it should be done in small increments using the appropriate Allen wrench[1][7][6].
While the underlying technology (such as the JLD Bridge Doctor) can be retrofitted to other guitars, the full Breedlove Truss System is specifically engineered for Breedlove instruments and is an integral part of their overall design philosophy[4][2].
By allowing the soundboard to vibrate more freely and evenly, the truss system enhances sustain, overtones, and tonal balance. Players often notice a richer, more dynamic sound with greater clarity and resonance compared to traditionally braced guitars[4][5][2].
Yes, the system is designed to provide a well-balanced tone suitable for a wide variety of musical genres, from fingerstyle and classical to rock and blues. Its versatility is one of the reasons it is favored by many professional musicians[7][4].
