Martin were established over 180 years ago and since then they have been one of the most well respected brands in guitar construction. The Martin OMPCA4 hails from the Performing Artist series and is loaded with high quality attributes but at a more attainable cost making it more accessible for guitarists with a smaller budget. An exquisite mix of tonewoods combined with top quality craftsmanship contribute to this guitar’s fine acoustic timbre which sounds excellent either natural or through an amp.


From the late 1920s, Martin designed a collection of 14-fret guitars which had a modified shape that incorporated the 000 body shape with a long scale neck, solid headstock and set measurements that were used for the bridge and nut width and these became known as Orchestra Models. The OMCPA4 has an orchestra dreadnought build with a single cutaway and this is seen to be one of the most versatile types of guitar model which feels ultimately comfortable to play.


Martin have employed a solid sitka spruce body top which helps the guitar to resonate freely due to its partnership with the dreadnought body shape. Hybrid "X" Scalloped bracing is used which combines scalloped bracing with A-frame technology. This relieves some of its extra body mass but also reinforces the body top at the same time, thus the guitar is able to vibrate freely while also being robust enough to endure hours of play.

The back and sides of the OMCPA4 are constructed using sapele tonewood which is a highly sustainable wood that works really well with the orchestra dreadnought body.


A select hardwood neck is firmly fitted to the body and is a standout feature of the OMCPA4. The neck has a Performing Artist profile which is slimmer for faster, easier playability. The neck tapers more slightly at the 12th fret, so incorporated with the cutaway in the body this allows for a much easier reach to the upper frets.

Married to the neck is a black richlite fingerboard adorned with white ABS offset dot inlays to guide you. Traditionally, acoustic guitars have 12 open frets however Martin broke the mould in adding two extra open frets and the OMCPA4 has this setup, thus having 14 open frets out of 20 in total.


Martin have fitted Fishman F1 Analog electronics to the OMPCA4 guitar making it ready for the stage. It features two controls, one for tone and the other for volume, just plug in using a ¼ inch instrument cable and you’re ready to play through an amplifier. The F1 also includes a built-in tuner which has an easy-to-read light up display so you can retune your guitar with minimal effort on stage. The F1 Analog battery can last up to 185 hours of continuous use, and a low battery LED indicator will show you when you need to recharge.


Chrome enclosed tuning machines with large buttons are fitted to the headstock to maintain and uphold tuning accuracy. The Performing Artist belly bridge forms a strong connection between the strings and the guitar body which means you can play for hours on end both on and off the stage with confidence.

The OMPCA4 has a neat, natural finish with a two ring rosette decorating the soundhole and the tortoise pickguard which also protects the soundboard from dirt and scratches. To further protect your axe, it comes supplied with a free hardshell case from Martin.

Martin have tried and tested many different methods and procedures when building various guitars, and the OMCPA4 is a superb electro acoustic guitar that is absolutely ready for any live performance. Entice your audience with the rich, full-bodied sound of the Martin OMCPA4, with sparkling highs and deep lows that will fill the room.
