Electronic Challenges of 20 String Amplification

Multiple String System Coverage

Amplifying 20 strings presents the most demanding challenges in acoustic-electric guitar design. The instrument features six main guitar strings plus 14 harp strings, each requiring pickup coverage for balanced amplified output. Standard pickup systems cannot adequately capture this many strings across such an extended frequency range.

Timberline addresses this difficulty through carefully positioned dual K&K Pure Mini systems that provide coverage for both string groups. The pickup placement accounts for the varying string heights and positions necessary to capture balanced output from all 20 strings.

Extended Frequency Range Requirements

The 20 string configuration extends frequency response to extremes that challenge conventional amplification equipment. Harp strings can reach frequencies below 25 Hz, requiring pickup systems and amplification equipment capable of reproducing infrasonic content without distortion.

The K&K system handles this extended range through specialized frequency response characteristics and impedance matching that works with various amplification systems, from acoustic guitar amplifiers to full-range sound reinforcement equipment.

Pickup System Architecture

Dual System Configuration

The dual K&K Pure Mini system uses one pickup for the main guitar strings and a second pickup positioned to capture the 14 harp strings effectively. This configuration provides separate signal paths that allow for independent level control and processing of each string group.

The pickup positioning requires precise installation to achieve balanced output across all strings while accounting for the difficult string geometry of 20 string construction. Factory installation ensures optimal placement that maximizes signal quality.

Signal Processing Considerations

The passive pickup design eliminates battery requirements while providing consistent output across the extreme frequency range. The system maintains proper impedance characteristics for compatibility with standard amplification equipment despite the unusual signal content.

Output levels remain balanced between main guitar strings and harp strings, preventing the bass-heavy harp strings from overwhelming the main guitar signal during amplified performance.

Amplification System Requirements

Full-Range Amplification Needs

The 20 string acoustic-electric harp guitar requires amplification systems capable of reproducing the complete frequency range from infrasonic harp strings to high-frequency guitar harmonics. Standard guitar amplifiers may not adequately reproduce the lowest frequencies these instruments produce.

Full-range acoustic amplifiers or PA systems typically provide the best results, as they include frequency response characteristics necessary for the extended range while maintaining the acoustic character essential for harp guitar tone.

Feedback Control Challenges

The large body size and multiple string systems create difficult resonance patterns that can lead to feedback issues in high-volume situations. The pickup system design minimizes these problems through careful positioning and passive electronics that reduce unwanted resonance.

Sound system setup becomes essential for preventing feedback while maintaining adequate volume levels for performance requirements. Professional sound engineering often becomes necessary for optimal results in challenging acoustic environments.
