Solar Guitars A1.6FRCAR Sustaniac+ review

The Solar Guitars A1.6FRCAR Sustaniac+ is a solid-body electric guitar built around a distinctive active pickup system and a Floyd Rose 1000 tremolo. Its listed price is 1,333, and it has been available since April 2026. No customer reviews are available, so this assessment focuses on the published specifications rather than user impressions or claims about playing experience.

The guitar has a Solar A-Type body made from alder, finished in high-gloss Candy Apple Red. There is no separate top. A maple neck and ebony fingerboard carry 24 stainless steel frets, with a Solar logo inlay at the 12th fret. The neck profile is C-shaped, and the fingerboard radius is 350 mm, or 13.78 inches. These details describe the construction, but they do not establish how the guitar feels in hand or how its finish holds up over time.

Neck, scale, and hardware

The 648 mm scale, also listed as 25.5 inches, is a common full-length electric guitar scale. The nut is 43 mm wide and uses a locking design. That locking nut works alongside the Floyd Rose 1000 tremolo, which has a 34 mm sustain block. Together, these components indicate a system intended to keep the strings secured at both ends during tremolo use. Actual tuning stability depends on setup, string installation, and maintenance, none of which can be confirmed from the specification sheet alone.

Solar specifies 18:1 locking machine heads and black hardware. Locking tuners can make string changes more straightforward by securing each string at the tuning post, while the locking nut clamps the strings at the headstock end once the guitar is set up. The supplied string gauges are.009 to.062, a set with a notably heavy low string compared with the upper strings. Players may want to confirm that this gauge suits their tuning and preferred setup before purchase.

Pickups and controls

The pickup layout combines two humbuckers with different roles. At the bridge is one Duncan Solar+ humbucker. In the neck position is a Sustainiac Stealth Pro humbucker. The guitar is listed as having active pickups, and its control set includes one volume control, a tone control with push-pull coil splitting, a three-way pickup selector, a Sustainiac on/off switch, and a Sustainiac mode switch.

The Sustainiac system is the defining electronic feature. Its neck-position unit is designed to produce sustain through an active circuit, with the dedicated switches providing control over activation and operating mode. The supplied data does not specify the available modes in detail, so buyers should consult the manufacturer's documentation for their exact behavior. The bridge pickup provides a separate humbucker voice, while the push-pull tone control adds a coil-splitting option. The stated specifications do not describe the resulting split-coil output or how it compares with a dedicated single-coil pickup.

Having several switches in addition to the pickup selector gives the player direct access to the listed functions, but the product information does not explain their placement or switching sequence. It is worth checking the control layout in product photos or a manual if quick access during performance is important.

Who should consider it?

The A1.6FRCAR Sustaniac+ is a specification-led option for players seeking a guitar with an active sustain system, a bridge humbucker, coil splitting, and a double-locking-style tremolo arrangement. Its 24 stainless steel frets, ebony fingerboard, locking nut, and locking tuners round out a feature set focused on hardware and electronic options. The high-gloss red finish and black hardware provide a clear visual contrast, though appearance remains a matter of preference.

There are practical tradeoffs to consider. A Floyd Rose 1000 tremolo and locking nut require a different setup routine from a fixed bridge, particularly when changing string gauges or tuning. The Sustainiac electronics also add controls and active circuitry that buyers should understand before choosing the guitar. The package includes neither a case nor a bag, so those may be additional costs. The sales unit is listed as one piece.

Technical verdict

On paper, the Solar Guitars A1.6FRCAR Sustaniac+ combines a maple neck, alder body, ebony fingerboard, stainless steel frets, active Sustainiac neck pickup, Duncan Solar+ bridge humbucker, and Floyd Rose 1000 tremolo. The specifications offer useful detail on its dimensions and controls, but there is no customer feedback or hands-on evidence to confirm comfort, sound quality, tuning behavior, or long-term reliability. Buyers should weigh the specialized electronics and tremolo against the added setup demands, and verify current availability and pricing with the seller.
