Course content

8 Chapters • 39 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Introduction to Guitar Technology

  • Lesson 1 • Guitar Anatomy and Component Identification

    Covers every structural part of acoustic, electric, and bass guitars. Establishes shared vocabulary used throughout all subsequent repair and setup procedures.

  • Lesson 2 • Instrument Inspection and Documentation

    Teaches systematic visual and tactile inspection before any work begins. Accurate documentation protects the technician and sets clear client expectations.

  • Lesson 3 • Workshop Safety and Organization

    Establishes safe handling of chemicals, sharp tools, and power equipment. An organised workspace reduces errors and protects both technician and instrument.

  • Lesson 4 • Essential Tools and Their Uses

    Introduces hand tools, measuring instruments, and specialty luthier tools. Correct tool selection prevents damage and ensures accurate, repeatable results.

Chapter 2See details

String Changes and Basic Setup

  • Lesson 1 • Nut Slot and Action Adjustment

    Addresses nut slot depth and saddle height to achieve correct open-string and fretted action. These two adjustments directly control playability and buzz.

  • Lesson 2 • Intonation Setting

    Explains how saddle position affects pitch accuracy across the fretboard. Correct intonation ensures the instrument plays in tune at every position.

  • Lesson 3 • Neck Relief Adjustment

    Teaches measurement and correction of neck bow using truss rod adjustments. Proper relief is the foundation for all subsequent action and intonation work.

  • Lesson 4 • String Types and Selection

    Explains gauges, materials, and winding styles for acoustic, electric, and bass strings. Matching strings to player style and instrument specs is the first setup decision.

  • Lesson 5 • String Removal and Installation

    Covers safe removal of old strings and proper installation techniques for each bridge and tuner type. Correct winding prevents slippage and tuning instability.

Chapter 3See details

Fretwork Fundamentals

  • Lesson 1 • Crowning and Polishing Frets

    Restores the rounded crown profile after leveling and brings frets to a mirror finish. Proper crowning ensures accurate intonation contact and smooth string bending.

  • Lesson 2 • Fret Condition Assessment

    Teaches identification of wear, divots, high frets, and loose frets using visual and tactile methods. Accurate diagnosis determines whether dressing or full refret is needed.

  • Lesson 3 • End Dressing and Fret Beveling

    Addresses sharp fret ends caused by fretboard shrinkage and teaches beveling for a smooth neck feel. End dressing is the finishing step of every fret job.

  • Lesson 4 • Fret Anatomy and Materials

    Describes fret wire dimensions, alloy types, and how they affect tone and wear. Material knowledge guides fret selection for refrets and replacements.

  • Lesson 5 • Fret Leveling Techniques

    Covers masking, leveling beam use, and stroke patterns to bring all frets to a uniform height. Leveling is the critical step before crowning and polishing.

Chapter 4See details

Full Refret Procedure

  • Lesson 1 • Safe Fret Removal

    Teaches heat-assisted fret pulling to minimise fretboard tearout on rosewood, ebony, and maple boards. Controlled removal preserves fretboard integrity for the new installation.

  • Lesson 2 • Fretboard Leveling and Slot Preparation

    Addresses fretboard surface leveling and slot cleaning to ensure new frets seat fully and evenly. A flat, clean fretboard is the foundation of a successful refret.

  • Lesson 3 • Fret Installation Methods

    Covers press-in and hammer-in installation techniques for straight and radiused fretboards. Consistent seating eliminates high frets and reduces post-installation leveling.

  • Lesson 4 • Refret Planning and Fret Selection

    Covers assessment criteria that justify a full refret and guides fret wire selection for the instrument. Proper planning prevents material waste and client dissatisfaction.

  • Lesson 5 • Post-Installation Finishing

    Completes the refret with end trimming, beveling, leveling, crowning, and polishing. Final setup confirms the refret meets playability and aesthetic standards.

Chapter 5See details

Nut Fabrication and Replacement

  • Lesson 1 • Slotting Nut Slots to Depth

    Covers string-spacing layout and filing each slot to the correct depth and angle for each string gauge. Slot depth is the most critical dimension for playability.

  • Lesson 2 • Nut Fitting, Gluing, and Finishing

    Finalises the nut with minimal adhesive, light sanding, and polishing to blend with the neck finish. Correct gluing allows future removal without damage.

  • Lesson 3 • Nut Materials and Selection

    Compares bone, synthetic, graphite, and brass nut materials by tone, lubrication, and workability. Material choice affects both sound and long-term tuning stability.

  • Lesson 4 • Shaping the Nut Blank

    Teaches rough shaping, fitting to the slot, and profiling the nut to match neck radius and headstock angle. Precise fit eliminates buzzing and improves sustain.

  • Lesson 5 • Nut Removal and Slot Preparation

    Covers safe removal of glued and press-fit nuts without damaging the headstock or fretboard. Clean slot preparation ensures a stable, rattle-free fit.

Chapter 6See details

Electronics Diagnosis and Repair

  • Lesson 1 • Pickup Installation and Adjustment

    Addresses mounting, wiring, and height adjustment of single-coil, humbucker, and active pickups. Correct height balances output, tone, and string pull.

  • Lesson 2 • Diagnosing Electrical Faults

    Teaches use of a multimeter to trace shorts, open circuits, and grounding failures. Systematic diagnosis saves time and avoids unnecessary component replacement.

  • Lesson 3 • Guitar Electronics Fundamentals

    Introduces signal flow, passive components, and basic circuit concepts specific to guitars. Understanding signal path is essential for efficient fault diagnosis.

  • Lesson 4 • Soldering Skills for Guitar Work

    Covers iron selection, tip care, solder types, and joint technique for guitar electronics. Clean solder joints prevent intermittent faults and signal loss.

  • Lesson 5 • Wiring Harness Assembly

    Covers building complete wiring harnesses off the guitar for clean, organised installation. Pre-built harnesses reduce time inside cramped control cavities.

Chapter 7See details

Tremolo and Bridge Systems

  • Lesson 1 • Bigsby and Vibrato Tailpiece Setup

    Covers installation, roller saddle use, and tension adjustment on Bigsby-style vibratos. Proper setup maximises tuning return on these low-travel systems.

  • Lesson 2 • Fixed Bridge Setup and Maintenance

    Covers tune-o-matic, hardtail, and wrap-around bridge adjustment and maintenance. Fixed bridges are the baseline before addressing the added complexity of tremolos.

  • Lesson 3 • Double-Locking Tremolo Systems

    Addresses setup, spring balancing, and fine-tuner adjustment on double-locking systems. These systems require precise spring-to-string tension balance for stable tuning.

  • Lesson 4 • Vintage Synchronized Tremolo Setup

    Teaches spring tension balancing, block angle, and saddle adjustment on vintage-style synchronized tremolos. Correct float angle is critical for tuning return and feel.

  • Lesson 5 • Tuning Stability Optimization

    Applies lubrication, string locking, and nut slot correction to maximise tuning stability across all bridge types. Stable tuning is the final measure of a successful setup.

Chapter 8See details

Advanced Setup and Playability Optimization

  • Lesson 1 • Acoustic Guitar Specific Adjustments

    Covers saddle shaping, bridge plate inspection, and top relief compensation unique to acoustic instruments. Acoustic setups must balance playability with acoustic volume and tone.

  • Lesson 2 • Final Quality Control and Delivery

    Establishes a systematic final inspection checklist before returning any instrument to a client. Consistent quality control builds reputation and reduces callbacks.

  • Lesson 3 • Bass Guitar Setup Specifics

    Addresses the longer scale, heavier strings, and higher tension unique to bass setup. Bass setups require wider relief tolerances and different action targets than guitars.

  • Lesson 4 • Multi-Point Action Optimization

    Addresses the interdependence of relief, nut height, saddle height, and fret condition as a unified system. Adjusting one parameter requires re-checking all others.

  • Lesson 5 • Player-Specific Setup Consultation

    Teaches structured intake interviews to capture playing style, genre, and feel preferences before setup. Accurate consultation prevents rework and builds client trust.
