- Agile Perihelion Pro 72628 TR MOD SS GL Green-Blue Burst 7-String Headless Guitar – 26.5"–28" Multiscale Tremolo, Fishman Fluence
Seven Strings, a 28" Bass Scale, a Tremolo, and Beautiful Gloss Green-Blue Burst! The Agile Perihelion Pro 72628 TR MOD SS GL offers a remarkable combination of seven-string extended range, 26.5"–28" multiscale construction, and an expressive headless tremolo system with a Cepheus locking nut.
Most seven-string multiscale guitars use fixed bridges. The Perihelion Pro offers something different: a specialized tremolo that brings vibrato, pitch dips, and expressive lead techniques to a longer-scale seven-string instrument.
The updated V3.7 configuration includes Fishman Fluence Modern three-voice active humbuckers, dual push-pull controls, 24 stainless steel frets, a Richlite fretboard with offset position markers, and a three-piece mahogany/maple bolt-on neck.
The Perihelion Pro's standout feature is its specialized multiscale tremolo system.
Combining a tremolo with fanned frets requires a bridge designed for different effective string lengths and saddle positions. The Perihelion provides this functionality across all seven strings.
Unlike a fixed-bridge extended-range guitar, the tremolo allows players to use the tremolo arm for expressive vibrato, pitch changes, and dramatic musical effects.
This makes the Perihelion particularly appealing to progressive metal, instrumental rock, fusion, and modern guitar players who want low-register versatility without giving up tremolo techniques.
The Perihelion Pro has a 26.5" scale on its highest string and a full 28" scale on its lowest string.
At the same pitch and string gauge, the longer bass-string scale produces additional tension compared with a shorter-scale guitar. This can help maintain a tighter picking feel and better note definition in lower tunings.
The shorter 26.5" treble scale provides a more manageable reach for chords, lead playing, and melodic passages than a uniformly 28" scale.
Compared with Agile's ultra-long 30" and 32" extended-range instruments, the Perihelion offers a more moderate multiscale while retaining useful additional bass-string length.
The guitar uses a Cepheus locking nut at the neck end and a specialized multiscale tremolo bridge.
The locking mechanism secures the strings while the tremolo bridge provides expressive pitch control.
Proper setup and tremolo balance are important to tuning performance. Changes in string gauge or tuning can affect the resting position of the bridge and may require adjustments to the tremolo springs.
The combination of headless construction, locking hardware, and a multiscale tremolo makes the Perihelion an unusual alternative to conventional seven-string guitars.
The V3.7 Perihelion features angled Fishman Fluence Modern active humbuckers with three selectable voices.
The neck pickup provides rich, articulate tones for expressive leads and clean passages, while the bridge pickup offers powerful attack and controlled low-frequency response suited to heavy rhythm playing.
The angled pickup placement complements the guitar's multiscale layout.
The updated V3.7 electronics provide three distinct sounds:
The push-pull volume control switches 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 three-voice arrangement replaces the older two-voice electronics described in earlier Perihelion listings.
The V3.7 revision adds important refinements to the Perihelion design:
The Green-Blue Burst seven-string Perihelion features a three-piece mahogany/maple neck with bolt-on construction and a comfortable C-shaped profile.
The multi-piece construction provides a stable foundation for the extended-range design.
A dual-action truss rod permits adjustments to neck relief for different playing conditions, string gauges, and tunings.
The Perihelion features a Richlite fretboard with offset position markers.
Richlite is a durable engineered composite material known for dimensional stability and consistent playing feel.
The offset markers complement the modern headless appearance while providing convenient fret position references.
The V3.7 Perihelion includes genuine Luminlay fluorescent position markers along the side of the neck.
These markers absorb light and glow in darker environments, helping players identify fret positions during performances on dimly lit stages.
The Perihelion Pro features 24 stainless steel frets, offering excellent wear resistance and smooth playing characteristics.
Stainless steel frets are particularly appealing for musicians who frequently use bends, vibrato, and technically demanding playing techniques.
The guitar features a compact mahogany body with comfortable contours and a double-cutaway design.
The body measures approximately 15" long, and the guitar's overall length is approximately 35", including the strap button.
The headless construction helps maintain a manageable overall size despite the 28" bass-string scale.
The striking Green-Blue Burst finish features attractive blue and green coloration with a figured burl appearance.
Its high-gloss surface highlights the color and figure, giving the instrument a distinctive look for stage and studio use.
The GL designation identifies the guitar's gloss finish.
The Perihelion Pro combines an uncommon seven-string multiscale tremolo with premium Fishman electronics and modern headless construction.
Its 26.5"–28" scale provides added low-string length without requiring the extreme reach of a 30" or 32" instrument.
The specialized tremolo and Cepheus locking nut support expressive pitch effects not available on fixed-bridge extended-range guitars.
The V3.7 Fishman three-voice system offers modern humbucker tones, alternate sounds, and an optimized single-coil-style voice.
Premium construction includes a Richlite fretboard, 24 stainless steel frets, a three-piece mahogany/maple bolt-on neck, and the latest V3.7 hardware refinements.
Finally, the Gloss Green-Blue Burst finish gives this unusual guitar a distinctive visual appeal.
Seven Strings. Multiscale Tremolo. Three Fishman Voices! The Agile Perihelion Pro 72628 TR MOD SS GL Green-Blue Burst offers extended-range guitarists an exciting combination of powerful tones, expressive tremolo performance, and modern design.
