Modified Dreadnought

The flagship Kostal guitar. The MD has the robust sound associated with a dreadnought guitar however, this “modified” version has a relocated waist that is a bit tighter than a traditional dreadnought and a larger sound hole which helps redefine it as a fingerstyle instrument, while still maintaining versatility for other playing styles. This guitar has everything a performing musician could want… deep resonant bass, balanced mid-range, and beautiful warm trebles coupled with projection and clarity that allow the musician to realize the complete dynamic range of their music and playing style.

Kostal Guitar’s second complete redesign, the MDW is the result of a collaboration with fingerstyle musician Michael Watts. It was an amazing project in which we both described what we wanted a guitar to do, and what we needed it to do, and then set out to create the guitar to meet those high expectations. The body is similar to a scaled down version of the MD, adding to its comfort and playability with total dimensions that make it only slightly smaller than the OM. The 12 fret body joint adds a level of beauty, warmth and sustain not experienced in other guitars, and the overall size and look is elegant in every way. This guitar was originally intended to be a “one off” and was named the “MD-W” for Modified Dreadnought – Watts, but I soon realized that MDW were Michael’s actual initials, and so the hyphen was removed, and Kostal Guitar’s first signature model was created. The MDW has since become my most popular model, and with every new MDW I make, I am reminded of just how extraordinary this instrument is.

Orchestra Model
Balanced and articulate, the OM could well be the perfect guitar if you were stranded on a deserted island and had to choose just one instrument to keep you company. The bass is warmer than in the MD, yet still prevalent, and comes forward with a more balanced and even tone across the entire spectrum. Smaller body size creates less projection than the MD, but provides for a more intimate playing experience for both the player and the listener. If you are someone who plays for your own enjoyment, or a small group of friends, or are a performer who often plays through sound systems, this guitar is exactly what you need.

Redesigned from the ground up, this guitar is the result of two years of development after an additional four years of building the MD and OM. The time spent building and listening to the OM and MD gave me an intimate understanding of how I was building my guitars and what I wanted the OO to do. I redesigned the bracing, depth, size, dome, and soundhole on the guitar to create a short scale, 12 fret guitar with all benefits of the OM in a smaller package. Despite its small stature, the OO has a beautifully robust and commanding resonance, making it the perfect choice for someone looking for a larger than life sound in a smaller package.

The Kostal Jumbo pairs the balance and intimacy of the OM with the volume, projection and clarity of the MD. Referred to by some as “an OM on steroids”, it’s the perfect instrument when you want that OM sound but need it to “go to 11”. The Jumbo is a large bodied guitar and is the go-to choice for those who can handle the size, or are looking for an amazing 12 string experience.
