Lava Music Lava ME 4 Spruce 41" Brown & Burlywood Electro-acoustic guitar

LAVA ME 4 Spruce 41" Smart Acoustic-Electric Guitar

The Lava Music LAVA ME 4 Spruce 41" Woodgrain Brown & Burlywood is a full-size smart acoustic-electric guitar pairing a heat-treated spruce top with HPL back and sides, along with the integrated HILAVA 2.0 touchscreen system. This 41-inch body holds 40% more internal air than the 36-inch version, expanding frequency range thanks to the proprietary Pano Sound Field technology layered over the 4-MASS acoustic structure. Featuring an asymmetric bracing pattern and a redesigned bridge, the instrument transfers string energy with greater efficiency. It serves players seeking a creative workstation in a full-size acoustic-electric, no external amp required.

Heat-Treated Spruce Top and Pano Sound Field

What sets this model apart from typical acoustic-electrics is the heat-treated spruce top, which is dried and lightened to enhance volume, frequency response, and resistance to changing humidity. With Pano Sound Field technology and the 4-MASS acoustic structure, the internal air volume expands, projecting a more immersive sound. A redesigned bridge with thinner, lighter wings and asymmetric bracing ensures smooth vibration transfer across the soundboard.

Spruce Top with HPL Back and Sides

This tonewood combination is engineered for stability, projection, and a distinctive two-tone look.

• Top Material: Heat-treated Spruce — punchy lows, clean mids, longer sustain
• The High-Pressure Laminate (HPL) used for the back and sides provides climate resistance and keeps the guitar lightweight for mobile players.
• Finish: Silver Plated — durable coating over the woodgrain brown & burlywood body

Okoume Neck with Carbon Reinforcement

Musicians benefit from a low 2.3 mm string action, carbon reinforcement rod in the neck, and a thin heel that unlocks the upper frets for adventurous playing.

• Neck Material: Okoume — stable, lightweight tonewood
• Fretboard in High-Pressure Laminate — smooth and durable under heavy playing
• String Action sits at 2.3 mm for light, easy pressing across long sessions
• Construction: Mechanical Joint — serviceable neck attachment

HILAVA 2.0 with L3 DSP Preamp

Onboard electronics turn this instrument into a self-contained creative studio. L3 preamp and DSP processor handle over 50 audio algorithms via FreeBoost 2.0, enabling access to 30+ effects, 100+ drum grooves, a looper, and a built-in tuner directly from the 3.5-inch touchscreen.

• Preamp: L3 with DSP processor (Sharc-DSP) — handles effects, looper, and tuner
• HILAVA 2.0 system with a 3.5-inch touchscreen runs LiveDrums, Create, and Learn apps
• Battery rated 5000 mAh / 3.8 V and supports wireless charging via the Space Charging Dock
• Tuner: Built-in — accessible directly from the touchscreen

Who Should Play the LAVA ME 4 Spruce 41"

This 41-inch model is ideal for gigging singer-songwriters and producers who want built-in effects, drum grooves, and a looper — all without carrying an amp. Solo performers benefit from the LiveDrums App and wireless Live Pedals, which add a band-like feel to any stage or living-room set. Practice-oriented players receive real-time feedback with Learn and Practice apps, and creative musicians can record three-track loops using the Create App, sharing them on the LAVA+ community. The Airflow Gig Bag supports easy transport for traveling musicians.

LAVA Music and the HILAVA Smart Guitar Vision

LAVA Music has established its reputation with carbon-fiber travel guitars and the HILAVA smart guitar platform, which incorporates an Android-based touchscreen, effects engine, and learning tools directly into the instrument. The Spruce series carries this vision into a full 41-inch body with a heat-treated spruce top—marking the first full-size entry in the ME 4 lineup and connecting traditional acoustic heritage with innovative, app-driven play.
