DIAGNOSTIC
To kick off the experience, we will conduct a thorough diagnostic of a guitar (one of yours or mine) to create a complete profile – the structural aspects, the playability of the guitar, and its acoustic signature – the musicality of the instrument. This is meant to deepen your understanding of how a guitar works, how it’s built, and how it can be improved.
Verbal History
The diagnostic starts with a short verbal history of the guitar.
- Type, Brand, Model
- Age
- Where purchased
- Satisfaction/Concerns
- Repair/service history
- Type of music played
playability
We’ll then explore Playability which measures how easy and satisfying the guitar is to play.
- Tuning accuracy – Pederson Strobosoft
- Action – measure string height
- Fret wear
- Clean top and fretboard
musicality
We’ll then explore Playability which measures how easy and satisfying the guitar is to play.
- Chladni patterns
- Frequency Response Curve with Signalscope
- Wolf notes
- Monopole Mobility with jig (versus other models)
- Modal Tuning Potential
- Add weight – bridge pins
- Reduce weight – shave bridge
- Reduce rigidity
structural aspects
Next is a thorough study of the Structural aspects, inside and outside the guitar.
- Top plate check
- Bridge check
- Neck check
- Peg head and tuner check
- Nut and saddle check
- Top deflection angle with jig
- Scope the inside
- Bracing style
- Scalloping
- Brace ends
- Linings
- Bridge plate
- Back bracing
- Top and back thickness with MagicProbe
- At edges of lower bout
- Plot several points
- Moisture in wood
This deep dive creates a total profile of the guitar. It’s also an effective way to prime our thinking just before we apply structured creativity techniques. It makes us more open and sensitive to seeing new sources of value in a guitar – how it’s made and played.
