SPIRA S-407 MBK 7-String Electric Guitar – Satin Black
The SPIRA S-407 takes the modern, stripped-back approach of the S-400 and extends it into seven-string territory. With a longer 26.5" scale, 24 jumbo frets, high-output Villain humbuckers, fixed bridge and locking tuners, it's purpose-built for players who want extended range without sacrificing definition or playability.
Finished in MBK Satin Black with matching black hardware, the S-407 looks suitably understated. There's nothing unnecessary here. It's a modern seven-string designed around heavy riffs, lower tunings and the additional range demanded by contemporary metal and progressive players.
The roasted poplar body is paired with a Canadian roasted maple neck and Hi-Grade Ebony Tech fingerboard, giving the S-407 a fast, solid feel with easy access across all seven strings and 24 frets.
26.5" Scale for Extended-Range Playing
One of the most important features of the S-407 is its 26.5" scale length.
That extra length helps maintain tension and definition on the low strings, particularly important on a seven-string where a standard guitar scale can sometimes feel loose at lower pitches.
The result is a firmer low B, better definition for fast rhythm work and a more controlled response when using high-gain sounds.
For players exploring lower tunings, extended chords and modern metal riffing, the longer scale makes a lot of sense.
Spira Villain 7-String Humbuckers
The S-407 is loaded with a pair of Spira Villain 7-string custom humbuckers.
Using ceramic magnets and approximately 12k output, they're designed specifically for powerful high-gain sounds while maintaining the clarity needed on an extended-range instrument.
That's particularly important with a seven-string. Big chords remain defined, low riffs retain attack and individual notes don't disappear when you start adding serious amounts of gain.
The controls are deliberately simple with Master Volume, Master Tone and an HH pickup configuration.
Modern D Roasted Maple Neck
The Canadian roasted maple neck uses Spira's Modern D profile, paired with a relatively flat 14" radius fingerboard and 24 jumbo frets.
It's a combination aimed squarely at modern playing techniques, providing plenty of room for fast lead work, wide bends and technical playing while keeping the additional width of a seven-string neck manageable.
At the nut, the S-407 measures 48mm wide, providing comfortable string spacing across all seven strings.
Fixed Bridge & Locking Tuners
A seven-string intended for heavy music needs to stay stable.
The S-407 uses a fixed bridge for straightforward setup, solid intonation and dependable tuning, while factory-fitted black locking tuners make string changes easier and help keep everything secure.
It's a particularly practical combination for players using alternate or lower tunings who don't want the additional complexity of a floating tremolo.

Who Is the SPIRA S-407 For?
The S-407 is for players who want to move beyond the range of a conventional six-string guitar.
It's particularly well suited to modern metal, progressive metal, djent, metalcore and other heavy styles, where the additional low string opens up new possibilities for riffs, extended chords and alternate tunings.
It's also an excellent introduction to seven-string guitar. The Modern D neck, 14" radius and straightforward fixed-bridge design keep things relatively familiar while giving you the extended range and longer scale associated with more specialised modern instruments.
Frequently Asked Questions
What is the advantage of a 7-string guitar?
A seven-string adds an additional low string, normally tuned to B, below the standard six guitar strings. This extends the instrument's lower range without sacrificing the familiar standard tuning across the remaining six strings.
Why does the S-407 have a 26.5" scale?
The longer 26.5" scale helps maintain string tension and definition on the lower strings. This produces a tighter response on the low B and can be particularly useful for heavy rhythm playing and lower tunings.
What pickups are in the SPIRA S-407?
The S-407 features a pair of Spira Villain custom seven-string humbuckers using ceramic magnets and approximately 12k output. They're designed for powerful, articulate performance under high gain.
Does the S-407 have locking tuners?
Yes. Black locking machine heads are fitted as standard.
Is the S-407 suitable for lower tunings?
Yes. The combination of its 26.5" scale length and fixed bridge makes the S-407 particularly well suited to lower tunings. String gauge and setup may need to be adjusted depending on how low you intend to tune.
Is a seven-string difficult to play?
There's an adjustment period because of the wider neck and additional low string, but the standard six strings remain in their familiar positions and tuning. For many players, the extra string quickly becomes a natural extension of the instrument rather than a completely different way of playing.
