12 String Acoustic-Electric Harp Guitar: Timberline's Approach to Amplified Extended Range

The 12 string acoustic-electric harp guitar bridges the gap between traditional acoustic harp guitar performance and modern amplified music contexts. Timberline Guitars produces these instruments with dual K&K Pure Mini pickup systems that capture both the main guitar strings and the extended harp strings, providing balanced amplification across the instrument's full frequency range. This electronic integration makes harp guitars practical for live performance situations where acoustic projection alone would be insufficient.
Electronic Challenges in Harp Guitar Design
Multiple String System Amplification
Amplifying a 12 string acoustic-electric harp guitar presents challenges that do not exist with standard six-string guitars. The instrument features two distinct string systems: the six main guitar strings and the additional harp strings, each requiring separate pickup coverage for balanced amplification.
Timberline addresses this depth through their dual K&K Pure Mini system, which uses one pickup for the main guitar strings and a second pickup positioned to capture the harp strings effectively. This approach ensures that both string systems maintain proper level balance when amplified.
Frequency Range Considerations
Harp guitars extend the frequency range significantly below standard guitar ranges, with some harp strings tuned as low as 41 Hz. Electronic systems must capture and reproduce these extended low frequencies without introducing unwanted noise or feedback.
The K&K pickup system handles this extended range through careful positioning and impedance matching that works effectively with various amplification systems, from small acoustic amplifiers to large concert sound systems.
Timberline Electronic Integration
Pickup System Design
The dual K&K Pure Mini system in Timberline's 12 string acoustic-electric harp guitar uses passive pickups that maintain the instrument's natural dynamics without battery power requirements. One pickup mounts under the bridge saddle to capture main string vibrations, while the second pickup positions near the harp strings to capture their output.
This configuration provides separate signal paths that can be mixed at the amplifier or sound system, allowing for level adjustment between the main guitar and harp string systems during performance.
Installation Methods
Timberline factory-installs the pickup system during construction, ensuring optimal placement and secure mounting that will not shift over time. The installation process requires precise positioning to achieve balanced output across all strings while maintaining the instrument's structural integrity.
The pickup wiring routes internally through the guitar to minimize external connections and reduce possible failure points. Output jacks mount securely in the guitar's end pin location, providing reliable connection for performance cables.
Performance Applications
Live Performance Requirements
The 12 string acoustic-electric harp guitar serves musicians who perform harp guitar music in contexts requiring amplification. Coffee house performances might need minimal amplification, while festival stages require sufficient output to compete with other amplified instruments.
The dual pickup system provides the output level and feedback resistance necessary for various performance contexts, while maintaining the acoustic character that defines harp guitar tone.
Band Integration
In full band contexts, the 12 string acoustic-electric harp guitar must compete with electric bass, drums, and other amplified instruments for sonic space. The electronic system allows for equalization and effects processing that help the instrument sit properly in ensemble mixes.
The extended low frequency range from harp strings can conflict with bass guitar frequencies, but proper mixing technique and the pickup system's clarity help resolve these future conflicts.
Recording Applications
Recording studios often prefer acoustic-electric instruments that provide both direct signal capture and acoustic microphone options. The 12 string acoustic-electric harp guitar offers this flexibility through its pickup system while maintaining acoustic properties suitable for microphone recording.
Many engineers mix direct pickup signals with microphone captures to achieve sounds that combine the immediacy of direct recording with the ambient qualities of acoustic recording.
Sound System Integration
Amplifier Compatibility
The K&K pickup system provides consistent impedance and output levels that work effectively with acoustic guitar amplifiers, PA systems, and recording equipment. The passive electronics eliminate the need for phantom power while maintaining signal quality across different system types.
Acoustic amplifiers designed specifically for acoustic guitars typically provide the best results, as they include equalization curves optimized for acoustic instrument frequency response and feedback control circuits.
Effects Processing
The 12 string acoustic-electric harp guitar responds well to effects processing designed for acoustic instruments. Reverb and chorus effects can amplify the natural harmonic content, while compression helps balance the output levels between main and harp strings.
However, the extended frequency range requires careful effects selection, as some effects processors may not handle the low frequencies from harp strings effectively.
Technical Specifications
Pickup Output Characteristics
The dual K&K system provides balanced output across the instrument's extended frequency range, with sensitivity curves optimized for both the main guitar strings and harp strings. Output impedance matches standard guitar input requirements for amplifiers and recording equipment.
Signal-to-noise ratio remains high due to the passive design and quality components, ensuring clean amplification even at high gain settings required for some performance contexts.
Electronic System Reliability
The passive pickup design eliminates battery-related failures while providing consistent performance over the instrument's lifetime. Quality components and professional installation ensure reliable operation under performance conditions.
The internal wiring uses high-quality cable and connections that resist corrosion and mechanical failure, important considerations for instruments that may be transported frequently.
Maintenance Requirements
Electronic System Care
The K&K pickup system requires minimal maintenance due to its passive design and quality construction. Periodic cleaning of output jacks and cable connections maintains optimal signal quality, while proper cable handling prevents damage to pickup components.
String changes require attention to pickup positioning, particularly for the bridge saddle pickup that must maintain proper contact with all strings for balanced output.
System Troubleshooting
Common electronic issues include loose connections, worn output jacks, and pickup positioning problems. Most issues can be resolved through basic maintenance procedures, though difficult problems may require professional service.
The dual pickup design means that partial system failure may affect only one string group, allowing continued performance with reduced capability until repairs can be completed.
