🎸 Can You “Break In” a New Acoustic with Bass Vibrations?
Inside the Strange, Clever, and Surprisingly Effective Closet Method
By Prodigal Guitars
Every guitarist knows the feeling: you bring home a brand-new acoustic, strum it, and think…
“It sounds good… but it still feels kinda tight.”
That’s normal. New acoustics often start out a little stiff — the wood hasn’t fully relaxed, the top hasn’t learned to dance yet, and the body hasn’t woken up. Over months (or years) of playing, the tone opens up:
- bass gets warmer
- mids get richer
- highs smooth out
- projection increases
- resonance deepens
This is the guitar becoming itself through vibration and time.
But impatient guitarists — innovators, mad scientists, tone chasers — have been asking for decades:
“Can I speed this up?”
Turns out… kinda, yeah.
And the method is wild.
🔊 The Famous Closet Method
Players have been doing this since the 70s:
- Put the acoustic guitar in a closet.
- Place a pair of speakers facing the guitar.
- Drape sleeping bags, quilts, or blankets over the whole setup.
- Play bass-heavy music for hours — even days.
Reggae, EDM, 808 loops, metal, drone tones, pink noise — anything with big, fat, low vibration.
The idea?
To replicate years of vibration in a weekend.
🎶 Why Bass? The Physics Behind It
Bass frequencies move more air.
More air = more force hitting the guitar top.
More force = deeper vibration into:
- the soundboard
- the bracing
- the neck joint
- the entire resonant chamber
Low frequencies behave like deep massage — slow, powerful, shaking the wood down to its fibers.
Some luthiers even say you can feel a stiff guitar physically loosen when exposed to strong, safe vibration.
🧪 Does It Actually Work?
Here’s the honest truth:
✔ Wood responds to vibration.
This is well-documented.
A guitar played regularly sounds better over time.
✔ Professional devices exist.
Tools like the Tonerite and PrimeVibe vibrate the guitar nonstop for days. People buy them because they notice a difference.
✔ The effect is real… but subtle.
The closet method won’t transform a cheap guitar into a Martin D-18.
But it can:
- warm the bass
- smooth the highs
- increase responsiveness
- open the top a bit
- reduce that “new guitar stiffness”
Most players report their guitar feels like it gained a few months of play wear.
✔ Some difference is psychological —
—but not all of it.
You can feel a “woken up” guitar.
Many describe it like the guitar finally learned how to breathe.
🛑 Is It Safe?
Yes — if you don’t do anything crazy.
Avoid:
- blasting the speakers at max volume
- overheating the guitar under too many blankets
- contact vibrations (don’t let speakers touch the guitar!)
- humidity outside 40–55%
- unstable stands or positions where it might fall
The goal is vibration, not violence.
❤️ What Music Works Best?
The consensus among tone-chasing weirdos (that’s a compliment):
- bass-heavy reggae
- EDM kicks
- continuous 40–100 Hz drones
- metal with big kick drums
- pink/brown noise
- looping low E or D notes
Some set it up overnight.
Some run it over a weekend.
Some do it a few hours a day for a week.
🎸 The Soul of It: A Jump Start, Not a Shortcut
Artificial aging isn’t a miracle worker.
It’s not meant to replace your hands, your touch, your years with the guitar.
What it does do:
- helps the top relax
- gets the resonance moving
- breaks the “green” feeling
- sweetens the voice earlier
Think of it like breaking in a baseball glove with oil and a ball.
You’re not cheating — you’re jump-starting the relationship.
🪵 The Bottom Line for Tone Seekers
Does the closet-and-speaker method work?
Yes — modestly, but genuinely.
Is it worth trying?
Absolutely. It’s fun, it’s harmless, and it gives your guitar a head start on its tone journey.
Will it replace years of playing?
No. That magic only happens through human hands.
But will it help your new guitar “wake up” sooner?
Very likely.
Tone is a journey. Vibrations are the fuel.
And sometimes, a closet full of blankets and bass is just the kick a young guitar needs.
