The guitar power cable

Guitar power cable I perkune audiophile cablesThe guitar power cable began its journey as an experiment, born from curiosity and a quest for excellence. And upon witnessing its remarkable performance, it was seamlessly integrated into our system in June 2024. 

Among my esteemed clientele, one stands out—a loyal patron for over two years. And a guitarist, with a notable array of guitars, amplifiers, and cabinets. He exemplifies a true connoisseur of musical craftsmanship.

Furthermore, this connoisseur of sound takes great pride in his gear, meticulously selecting each component to craft his signature tone. Also, his discerning eye for quality and dedication to his craft serve as a testament. And about two months ago, he approached me with a specific request. To create a power cable capable of replacing the outdated cable originally fitted to his prized guitar amplifier. And his desire was simple yet profound—he sought to enhance the amplifier’s sound quality,

Performance reaction

My customer’s reaction to the guitar power cable, was nothing short of gratifying. And he likened the cable’s effect to the removal of a blanket from over the amplifier. Also, he expressing sheer delight at the elevated sound quality. And, his satisfaction was such that he promptly placed an order for a second cable. Following the same meticulous process as before, the second cable was crafted with precision and care, then promptly dispatched to America. And once again, the results surpassed expectations, prompting the order of two additional guitar power cables.

Cable construction

Cable plug componentsIntroducing, the precision-engineered plug utilised in our Guitar power cable. And allowing redefined excellence with every detail. Also, this robust Brass plug is available with US or EU rhodium-plated pins. And stands as a testament to unparalleled craftsmanship. Weighing twice as much as standard equivalents (14.6 to 30.8 grams), its sturdy build ensures durability and reliability under all conditions.

Internally, the plug also, boasts Rhodium-plated screws and secondary PVC shielding. Also, a secondary isolation ring is fitted. And so further enhancing its performance and safeguarding signal integrity. Encased in a sleek Carbon Fiber body, this plug seamlessly integrates style with functionality. And the incorporation of a ferrite sleeve, plus a silicone sleeve underscores its pivotal role in the audio chain.

The IEC connection is left open for you to fit to the amplifier yourself (or a qualified electrician). The live side is brown, neutral is blue and earth is Yellow/green striped. Also, the cable is covered with anti-static protection tape all the way, And the end is reduced in size to enable the cable to fit inside the cabinet connecting hole.

The Ferrite collar

The Ferrite collar

An effective method for filtering high frequency power supply noise and cleanly sharing similar voltage supply rails. That is, analog and digital rails for mixed-signal ICs. Also, while preserving high frequency isolation between the shared rails is the use of a ferrite collar. And a ferrite collar is a passive device that filters high frequency noise energy over a broad frequency range. Also, becoming resistive over its intended frequency range. And dissipating the noise energy in the form of heat. 

Ferrite has been used for years and more than just a mere accessory. Serving as the foundational elements of an exceptional audio experience. And whether you’re a professional musician or an avid audiophile, the Guitar power cable will elevate your sound to unprecedented height

The guitar cable is made in a three meter length. And a distinguishing feature is the shielding. Power cables from other manufacturers are rarely shielded. Also, the shielding is in the greatest extent responsible for minimising the impact of electromagnetic interference on other audio cables. Also, the combination of the components brings you a cable offering a black background.

High quality OFC cable. Shielded braid with a density of 80% protects against interference in audio Hi-Fi, High-End systems. And suitable for the following –

Marshall, Gibson, Fender, Selmer, Silvertone, Supro, Ampeg, Vox, Magnatone, Danelectro, Gretsch, Watkins, Burns, Traynor, Harmony, National, Sound City, Orange etc.

Cable Current flow

The way current flows through a power cable is governed by fundamental principles of electromagnetism, primarily Ohm’s law and the principles of electric fields. Let’s break down how current flows through a power cable:

1. Ohm’s Law:

Ohm’s law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to the resistance (R) of the conductor. Mathematically, Ohm’s law is represented as:


In the context of a power cable:

  • Voltage (V): The potential difference between the two ends of the cable, provided by the power source.
  • Current (I): The flow of electric charge (electrons) through the conductor.
  • Resistance (R): The opposition offered by the conductor to the flow of current, determined by the material, length, and cross-sectional area of the conductor.
2. Conduction of Current:

When a voltage is applied across the ends of a power cable, an electric field is established within the cable. This electric field exerts a force on the free electrons within the conductor, causing them to move. In a conductor like copper, which typically has low resistance, electrons can move relatively freely.

3. Movement of Electrons:

As electrons move in response to the electric field, they flow from the negative terminal (cathode) of the power source towards the positive terminal (anode). This movement of electrons constitutes an electric current. In a DC (Direct Current) circuit, electrons flow in one direction continuously. In an AC (Alternating Current) circuit, the direction of electron flow reverses periodically as the voltage alternates.

4. Distribution of Current:

The distribution of current within the power cable depends on various factors:

  • Conductor Geometry: Current tends to concentrate near the surface of the conductor due to a phenomenon known as skin effect, particularly at higher frequencies in AC systems.
  • Cross-Sectional Area: Current density is higher in regions of the conductor with smaller cross-sectional areas, leading to increased heating in those areas.
  • Temperature: The resistance of the conductor increases with temperature, affecting the distribution of current and potentially leading to localized hotspots.
5. Magnetic Fields:

When current flows through a conductor, it generates a magnetic field around the conductor according to Ampere’s law. This magnetic field interacts with any nearby conductors or magnetic materials, influencing the distribution of current and potentially causing electromagnetic interference (EMI) in sensitive electronic devices.

6. Losses and Efficiency:

Although power cables are designed to minimize resistance and energy losses, some amount of energy is dissipated in the form of heat due to the resistance of the conductor. This is known as resistive or I²R losses. To improve efficiency and minimize losses, cables are often made of materials with low resistance and designed with optimal dimensions for the intended application.


In summary, current flows through a power cable in response to the voltage applied across it, driven by the electric field established within the conductor. The distribution of current is influenced by factors such as conductor geometry, cross-sectional area, and temperature. Understanding these principles is essential for designing efficient and reliable electrical systems using power cables. And by construction the cable in the correct manner provides you with a cables that will improve performance in many areas.

    1. Hello Pele
      And the reason the cable is 1.5 is because my customer wanted it to be flexible and easily
      moved around. And I can easily make the cable 2.5 as my supplier also has it. what is the
      make of amp and year to which you will use?

      Best regards
