How to Blind Test Tonewood Claims on Electric Guitar (Without Fooling Yourself)

If you want to test tonewood claims honestly, you need a protocol that removes expectation bias.

Most “wood comparisons” online aren’t controlled. Different pickups, pickup heights, strings, and amp settings make the result meaningless.

This guide gives you a simple, practical method that actually tells you something.

What You’re Testing

You are not testing “which guitar sounds better.”

You are testing whether wood/construction differences are reliably audible when major variables are controlled.

Ground Rules

Keep these constant across trials:

Same player
Same amp and settings
Same cab/speaker
Same room and mic position (if recording)
Same string gauge and condition
Same pickup type and wiring (or as close as possible)
Same pickup height
Same tuning and intonation state
Same pick and playing pattern

If these aren’t controlled, results are mostly noise.

Equipment Checklist

2 electric guitars you want to compare
Accurate tuner
Feeler gauge/ruler for pickup height
DAW or looper/reamp setup (preferred)
SPL meter plugin or meter app for level matching
Randomizer (coin flip, app, or friend)
Notes sheet/spreadsheet

Step 1: Match Setup Conditions

Before any test:

Install comparable fresh strings (same brand/gauge if possible).
Set both guitars to similar relief and action.
Match pickup heights carefully (this is huge).
Tune both guitars precisely.

Skipping this step invalidates the test.

Step 2: Use Reamping if Possible (Best Method)

Best approach:

Record a clean DI performance once.
Reamp that exact performance through each guitar chain/path.

Why: identical performance removes pick attack and human variation.

If reamping isn’t possible, use:

strict click track
repeated phrase pattern
multiple takes and averaging

Step 3: Level Match Correctly

Human ears prefer “louder = better.”

Match levels within about ±0.5 dB before comparing.

If levels differ more than that, your conclusions are suspect.

Step 4: Blind Randomized Trials

Do A/B/X style testing:

A = Guitar 1
B = Guitar 2
X = unknown (randomly A or B)

Run at least 10–20 trials.

If your correct identification rate is near chance, audible difference is likely small in that context.

Step 5: Test Multiple Contexts

Do separate rounds for:

Clean tone
Edge-of-breakup
High gain
Full mix (drums/bass backing)

Many subtle differences shrink dramatically in a mix.

Step 6: Track Both “Sound” and “Feel”

Log two separate categories:

Audible difference (recorded/listener side)
Playing feel (your hands/response)

Sometimes feel is clearly different even when blind audio differences are minimal. That’s still useful data.

Sample Notes Template

Use columns like:

Trial #
Context (clean/gain/mix)
X guess (A/B)
Correct? (Y/N)
Confidence (1–5)
Notes (attack, sustain, brightness, low-end feel)

After 20+ trials, patterns become clearer.

Common Testing Mistakes

Not matching pickup height
Using old strings on one guitar and new on another
Comparing at different volume levels
Changing amp settings between takes
Declaring conclusions from 2–3 impressions
No randomization (knowing what you’re hearing)

What Good Conclusions Look Like

Good conclusion:

“In clean solo tones I could identify Guitar A above chance; in high gain and full mix, differences were near chance.”

Bad conclusion:

“Mahogany destroys alder always.”

Specific context beats sweeping claims.

Final Take

Tonewood discussions get better when we test honestly.

A blind protocol won’t kill your preferences — it makes them more trustworthy.

If a guitar inspires you and feels right, that matters.
Just don’t confuse preference with proof.
