- Agile Perihelion Pro 72628 TR MOD SS Black Sparkle 7-String Headless Guitar – 26.5"–28" Multiscale Tremolo, Fishman Fluence Advanced Order (12-10)
Seven Strings, a 28" Bass Scale, and a Tremolo! The Agile Perihelion Pro 72628 TR MOD SS Black Sparkle brings together an uncommon combination of seven-string extended range, 26.5"–28" multiscale construction, and a specialized headless tremolo system with a Cepheus locking nut.
Most extended-range multiscale guitars use fixed bridges. The Perihelion Pro offers an alternative for players who want extra low-string length without giving up expressive tremolo techniques.
The updated V3.7 configuration features Fishman Fluence Modern three-voice active humbuckers with two push-pull controls, stainless steel frets, a Richlite fretboard with offset position markers, and a three-piece mahogany/maple bolt-on neck.
The specialized tremolo bridge is the defining feature of the Perihelion Pro 72628 TR.
On a conventional multiscale guitar, the strings use different scale lengths and the individual saddles must accommodate the fanned-fret geometry. Combining that arrangement with a functioning tremolo requires a bridge designed specifically for the multiscale layout.
The Perihelion Pro provides that capability while retaining seven-string extended range and a full 28" bass-string scale.
The tremolo arm allows expressive vibrato, pitch dips, dramatic musical effects, and lead techniques that are unavailable on a conventional fixed-bridge guitar.
Other manufacturers offer certain headless multiscale tremolo models, but the combination of seven strings, a full 28" bass scale, and locking tremolo hardware is particularly uncommon.
The Perihelion Pro features a 26.5" scale on the highest string and a full 28" scale on the lowest string.
At an equivalent pitch and string gauge, the longer bass-string scale provides additional tension compared with a shorter-scale instrument. This can help maintain a tighter picking feel and improved low-note definition when using lower tunings.
The shorter 26.5" treble-string scale offers a more manageable playing feel for melodic passages and leads than a uniformly 28" scale.
The fanned-fret layout provides a graduated scale across all seven strings, combining the advantages of longer bass-string length and shorter treble-side reach.
The Perihelion Pro uses a Cepheus locking nut at the neck end to secure the strings in its headless configuration.
The multiscale tremolo bridge provides expressive pitch control while accommodating the different effective scale lengths of the seven strings.
Unlike the individual fixed saddles used on many other Agile headless guitars, the Perihelion's tremolo bridge moves when the tremolo arm is operated.
As with other locking tremolo systems, proper setup, string installation, and bridge balance are important for consistent tuning performance.
Significant changes in tuning or string gauges may require adjustments to the tremolo spring balance, neck relief, action, and intonation.
The V3.7 Perihelion Pro is equipped with angled Fishman Fluence Modern active humbuckers featuring three selectable sounds.
The active pickup system provides articulate modern tones suited to high-gain rhythm playing, expressive leads, and clean passages.
The angled pickup arrangement complements the multiscale geometry, while the three-voice electronics provide considerable versatility beyond a conventional two-voice humbucker system.
The V3.7 electronics provide three distinctive pickup sounds:
The push-pull volume control selects between the two humbucker voices, while the push-pull tone control provides access to the third, single-coil-style sound.
A three-way pickup selector allows neck, combined, and bridge pickup settings.
This updated arrangement replaces the older two-voice specification previously associated with earlier Perihelion models.
The V3.7 revision incorporates improvements to playability, string retention, and electronic versatility.
The Perihelion Pro features a Richlite fretboard with modern offset position markers.
Richlite is an engineered material valued for its durability, dimensional stability, and smooth playing characteristics.
The offset markers provide useful visual references while complementing the guitar's contemporary design.
The Perihelion Pro features 24 stainless steel frets, providing excellent resistance to wear and smooth playing characteristics.
Stainless steel frets are especially useful for musicians who frequently use bends, vibrato, and other expressive techniques.
The improved V3.7 neck heel helps provide access to the highest register.
The guitar features a three-piece mahogany/maple neck with bolt-on construction and a C-shaped profile.
The multi-piece neck provides a stable foundation for seven-string playing and the extended multiscale layout.
A dual-action truss rod allows adjustment of neck relief to accommodate changes in string tension and playing preferences.
The Perihelion Pro features a compact mahogany body with comfortable contours and a modern double-cutaway shape.
At approximately 35" overall, including the strap button, the headless design helps keep the instrument manageable despite its 28" bass-string scale.
The contoured body makes the guitar suitable for playing while seated or standing.
The Black Sparkle finish adds a distinctive visual character to this specialized seven-string guitar.
The sparkling black appearance complements the unusual tremolo hardware and modern headless design, giving the Perihelion Pro a striking stage presence.
The Agile Perihelion Pro 72628 TR provides an unusual combination of extended-range performance and tremolo expression.
Its 26.5"–28" multiscale offers additional bass-string length for lower tunings, while the specialized tremolo bridge enables expressive vibrato and pitch effects.
The Cepheus locking nut helps secure the strings, and the V3.7 Fishman Fluence three-voice electronics offer a wide range of modern tones.
Premium features include 24 stainless steel frets, a Richlite fretboard, a three-piece mahogany/maple bolt-on neck, and a compact contoured mahogany body.
Extended Range Without Giving Up Tremolo Expression! The Agile Perihelion Pro 72628 TR MOD SS Black Sparkle is designed for guitarists who want the low-register advantages of a multiscale seven-string and the creative possibilities of a tremolo-equipped instrument.

Note: This is the three-voice electronics reference used on the updated Agile headless models. Tremolo hardware and instrument-specific wiring layouts may differ.
Changes in string gauges or tuning can affect the balance between string tension and tremolo spring tension. After making significant changes, the bridge position, neck relief, action, and intonation should be checked.
Factory String Gauges (High to Low): .010, .012, .016, .024w, .032w, .042w, .054w
The guitar's 26.5"–28" multiscale offers flexibility for lower tunings with appropriately selected strings.
The specialized multiscale tremolo must remain balanced against string tension. Changes to gauge or tuning may require tremolo spring adjustment, neck relief adjustment, and intonation setup.
The Perihelion combines seven strings, a 26.5"–28" fanned-fret multiscale, a specialized headless tremolo bridge, and a Cepheus locking nut. This combination is uncommon among extended-range guitars.
Yes, but the selection is relatively limited. Some manufacturers offer headless seven-string multiscale tremolo guitars. The Perihelion Pro is particularly distinctive because it combines this feature with a full 28" bass-string scale.
The guitar features a 26.5"–28" multiscale, with the shortest scale on the highest string and the longest scale on the lowest string.
The longer bass-string scale provides additional string tension at the same pitch and gauge compared with a shorter-scale guitar. This can help maintain control and definition when using lower tunings.
It has a specialized multiscale tremolo bridge, not a fixed bridge. The tremolo arm allows expressive changes in pitch during performance.
Yes. The tremolo provides pitch modulation for expressive vibrato, pitch dips, and other tremolo-based playing techniques.
Yes. It uses a Cepheus locking nut at the neck end of its headless design.
No. Most Chiral Nirvana models feature fixed individual headless saddle/tuners. The Perihelion uses a specialized multiscale tremolo that moves when the tremolo arm is operated.
Yes. The V3.7 Perihelion uses Fishman Fluence Modern active pickups with two humbucker voices and a third optimized single-coil-style sound.
The push-pull volume control switches between the two humbucker voicings. The push-pull tone control provides access to the third, single-coil-style voice. A three-way selector chooses neck, both pickups, or bridge.
The current V3.7 version offers three Fishman pickup voices through two push-pull controls. Earlier versions used a two-voice arrangement with a single push-pull voice selector.
The guitar features two angled Fishman Fluence Modern active seven-string humbuckers with three selectable sounds.
