The MusicStreet Setup Advantage: Why Your Sigma Deserves It
Sigma acoustic guitars are celebrated for their exceptional build consistency, solid wood tops, and comfortable neck profiles. However, because these guitars are crafted from real, highly resonant solid tonewoods, they are sensitive to temperature and relative humidity changes during transit. A factory setup, while excellent, is rarely optimized for your specific playing style or the UK climate.
At MusicStreet, we treat every Sigma with the reverence it deserves. We perform a **free £75 professional workshop setup** on every single Sigma acoustic guitar we sell. Our expert luthiers adjust the truss rod, file the nut slots, precision-shave the bridge saddle, and polish the frets to ensure your new instrument plays with a comfortable, buzz-free low action straight out of the box.
🔧 Free £75 Professional Setup
Every Sigma acoustic guitar is individually set up in our in-house workshop. We adjust the action, intonation, and neck relief to match your playing style, ensuring it plays perfectly straight out of the box.
🛡️ 12-Month Warranty
We stand behind every instrument we sell. All of our Sigma acoustic guitars come with a full 12-month warranty, giving you complete peace of mind with your purchase.
🚚 Free UK Delivery & 14-Day Returns
Get free, fully insured UK shipping on all orders over £99. If the guitar isn't the perfect fit for your hands, return it to us within 14 days for a hassle-free refund or exchange.

Frequently Asked Questions About Sigma Guitars
Are Sigma guitars made by Martin? +
Sigma was originally launched by C.F. Martin & Co. in 1970 to compete with high-quality Japanese imports. While Sigma is now an independent company, they continue to build vintage-inspired instruments that utilize classic Martin-style body shapes, bracing patterns, and aesthetic designs, offering legendary American acoustic heritage at an incredibly accessible price point.
What is included in your £75 professional setup? +
Our expert in-house technicians perform a complete multi-point inspection. This includes adjusting the neck relief (truss rod), setting the optimal string action (height) at both the nut and bridge saddles, setting the intonation, cleaning and conditioning the fretboard, polishing the frets, checking all electronics/pots, and installing a fresh set of premium strings.
Do Sigma acoustic guitars have solid wood tops? +
Yes, almost all Sigma acoustic guitars feature solid wood tops (typically solid Sitka Spruce, Western Red Cedar, or Mahogany). Solid tops are highly superior to laminated tops because they vibrate more freely, delivering significantly better projection, dynamic range, and a tone that matures and improves the more the guitar is played.
Can I trade in my old gear toward a purchase? +
Absolutely. We offer a highly competitive part-exchange program. You can bring your gear directly to our Huntingdon showroom for an on-the-spot valuation, or contact us online with photos and details to receive a preliminary trade-in estimate.
The Sigma Legacy: Martin's Blueprint for Value
The story of guitar sigma began in 1970, when C.F. Martin & Co. created the brand to offer high-quality, reliable acoustic guitars built to Martin's exacting specifications at a fraction of the cost. This rich heritage of acoustic innovation is preserved in every acoustic guitar sigma built today.
By combining traditional acoustic construction methods—such as hand-scalloped bracing and solid wood tops—with modern manufacturing precision, Sigma offers the iconic designs, rich harmonic complexity, and robust projection of legendary American acoustics at a highly accessible price point.

2. The 15 Series (Warm Mahogany Resonance)
For the player who values organic, natural beauty and pure, warm acoustic tone. The 15 Series features solid mahogany tops paired with mahogany back and sides, finished with a beautiful, thin satin finish that allows the wood to vibrate freely. These instruments offer exceptional note definition, warm midrange punch, and a highly responsive touch.
3. The Travel Series (Compact Companions)
The ultimate travel companion. Sigma's travel guitars (such as the TM-12 or TM-15) feature a compact, 3/4-sized body with a solid wood top and highly durable back and sides. They deliver a surprisingly robust, full-bodied projection despite their compact size, making them the perfect grab-and-go instruments for beach trips, open mic nights, and songwriting sessions.
4. The MusicStreet Difference: Workshop-Prepared Playability

5. Frequently Asked Questions (FAQs)
Are Sigma acoustic guitars made by Martin?
While Sigma was originally launched and owned by C.F. Martin & Co. in 1970, the brand is now independently owned. However, Sigma continues to build their guitars to the same classic Martin-style blueprints, utilizing traditional bracing patterns and body shapes to deliver authentic, vintage-inspired acoustic tones at an incredible price point.
What is the difference between a solid top and an all-solid guitar?
A solid top guitar features a solid piece of wood for the soundboard (the top of the guitar), which is the most critical component for tone and projection, paired with layered (laminated) back and sides for added durability. An all-solid guitar features solid wood for the top, back, and sides, offering maximum resonance, dynamic range, and a tone that matures and sounds even better with age.
Does my Sigma acoustic guitar come set up?
Yes. Every Sigma guitar purchased from MusicStreet receives a professional, custom setup in our in-house workshop before dispatch. If you have specific preferences for string gauge or tuning, simply let us know when placing your order, and our techs will configure it to your exact specifications.
Can I try these guitars in person?
Absolutely. We welcome you to visit our independent showroom at 10 Chequers Court, Huntingdon, Cambridgeshire. You can get hands-on with our collection, test them through premium amplifiers, and get honest, expert advice from our team of working musicians.
