Technical Specifications — Heartforge.
Heartforge Metallherz is not merely an instrument, but a stage artifact forged at the intersection of metal, mechanics, and ritual aesthetics.
The guitar is designed as an extension of the band’s sonic and visual identity: industrial and symphonically saturated.
Concept.
The body shape references gothic weaponry and temple architecture.
Relief carving with demonic motifs and a mechanical “heart” with internal illumination symbolize a living machine — a source of rhythm, noise, and melody.
This instrument feels equally at home on large stages, in studios, and under the lights of music videos.

Stage Effect.
The built-in “heart” illumination functions as a visual focal point on stage.
The instrument’s silhouette is instantly recognizable even from a distance.
It is not merely a sound source, but part of the stage architecture — as if it grows from it and responds together with light, vibration, and the audience’s breath.

Tonewoods and Sonic Role.
For Heartforge Metallherz, tonewoods were selected specifically for low tunings, high gain environments, and clarity within dense industrial-symphonic mixes.
Body Woods.
Solid hardwood with dense grain structure — Mahogany with figured maple top.
This provides:
- controlled, tight low end without muddiness
- resistance to unwanted resonances
- stable response under aggressive attack and palm muting
The multi-layer body construction further enhances sustain and frequency balance, especially important for a 7-string instrument in extreme genres.
Neck Woods.
High-stability selected hardwood with low sensitivity to humidity and temperature changes — Mahogany with ebony fingerboard.
This ensures:
- tuning stability
- precise attack
- comfort in low tunings and with heavy strings
Hand Carving & Artistic Elements.
The demon figure on the body is fully hand-carved, without templates or CNC routing.
Every line, texture, and surface detail is shaped manually, making each instrument unique.
The carving is not purely decorative:
- it emphasizes the concept of a “living mechanism”
- visually connects the instrument to the Metallherz aesthetic
- transforms the guitar into both stage object and art artifact
Metallic plates and decorative elements are integrated without disrupting acoustic balance, preserving natural wood resonance.
Sound.
The sound of Heartforge is based on a dense, aggressive, yet alive tone, oriented toward industrial and symphonic metal.
It is designed for low tunings and high gain while maintaining clarity and control in extremely dense arrangements.
Low End.
Massive and controlled.
The 7th string is tight, stable, and defined — without flabbiness or uncontrolled resonance, forming a solid foundation for riffs and palm-muted passages.
Midrange.
Rich and dominant.
The guitar does not disappear in orchestral layers, synthesizers, or industrial textures, instead forming a dense “wall of sound.”
High End.
Clear and articulate.
Attack is well-defined; riffs cut through the mix without excessive harshness or artificial grain.
Playing Feel.
Rigid and controlled.
Immediate response to picking dynamics, strong sustain under high gain, and precise articulation.
Final Character.
Heartforge Metallherz sounds like a living machine:
heavy, aggressive, and musical at the same time — perfectly suited for industrial-symphonic and heroic metal, and for the stage identity of the band Metallherz.
