"I am a designer and constructor of nylon and steel string guitars working from a studio located in Ontario, Canada.

Dating Edward Klein Guitars

I began serializing my instruments in 2001. The first two numbers after my initials EK in the serial number refer to the year, followed by the sequential number built in that year. For example, EK0703 refers to the third guitar produced in 2007, and EK0803 the third in 2008. This information is located on the label and also stamped into the upper bout block within view looking through the soundhole." [Edward Klein, Luthier, email 10/4/2008]

Klein's raised fingerboard "floats" UNATTACHED to the sound-board, allowing it complete vibrational freedom, resulting in superior tone, volume, and sustain. Transcending Millennium criticisms, particularly those associated with "lack of soul," Klein, epitomizes German Artisan/Craftsmen by impeccably bringing this guitar to life. In doing so, he spared no expense acquiring the finest woods and materials:

All designs/creations are named after American Indian river names. Chesapeake line models Choptank, Severn, Potomac & Patuxent are named after tributaries to the Chesapeake Bay while the Influence line Kenai, Keya, Chena, Sheyenne are named after rivers in North America.

Dating Knaggs guitars

All of our models have their own serial number starting at #1 ... the first guitars were made from January 2010 - March 2010. Each model of our range has their own serial-number system ... so there is a Kenai # 34, a Keya # 34 etc ... it tells us exactly how many of the different models have been made at any given point in time. Date of manufacturing is not on the instrument but we keep track through an internal serial # data base"
Launch of the brand took place in Frankfurt, Germany in April 2010. We initially made 9 guitars for the Frankfurt show. Production started in May 2010 at our Greensboro, MD shop. We have made close to 1,000 guitars by now. [Source, images and 2012 Knaggs guitar pdf article Peter Wolf, email 11/1/2013]

Ian Kneipp


Ian Kneipp was born in Australia in 1947. He undertook university studies in marine and freshwater biology, receiving a BSc (Hons) in 1975 and PhD in 1980. He continued working in the area of biological research for some years, but eventually decided to pursue his long held interest in woodwork as an occupation.
In 1988, he began woodwork part time (in conjunction with environmental consulting) while living at Glen Innes in New South Wales. This led to his association with Eugene Philp and Greg Smallman. Eugene had learned the Smallman method of guitar making under Greg's direct supervision during the 1980s. Ian Kneipp began making guitars in 1992 under Eugene's supervision. Although the regular valuable advice received from Greg Smallman during this time is gratefully acknowledged, Ian was at no time a Smallman 'apprentice' nor have his guitars been produced under the direct supervision of Greg Smallman.

They were made in Uralla, NSW

Design and Construction
Kneipp classical guitars use a lattice-braced western red cedar soundboard. This design has the potential to produce guitars with outstanding dynamic range and fullness of tone.

Design Features
Kneipp guitars make extensive use of epoxy resin glues and carbon fibre reinforcement. The use of this technology allows the production of an instrument with exceptional strength, stability and performance.
Kneipp guitars are guaranteed against structural failure during normal use.

Body - back and sides of veneers laminated using epoxy resin for strength and stability; the back is arched for strength and some players find this shape also makes the guitar more comfortable to hold.

Soundboard - lattice braced Western Red Cedar. The soundboard and bracing system are extensively reinforced with carbon fibre and epoxy resin. The top is attached to the body of the guitar using epoxy resin glue.

Bridge - crafted from Paduak which gives superior performance. The bridge is attached to the top using Titebond aliphatic resin glue and further anchored to the soundboard and braces with four carbon fibre pins and epoxy resin.

Tone Ring - a rigid laminated support for the soundboard which enhances performance and stability. The strength and rigidity of this structure helps to confine the energy of the vibrating top which would otherwise be dissipated in the sides and back of the instrument.

Neck - Queensland Maple, Brazilian Mahogany or New Guinea Rosewood, with steel truss rod.

Fingerboard - laminated for stability with a polished ebony surface, shaped to provide string clearance bias so all strings are equidistant above the soundboard. Standard fingerboard with 650mm scale length and 20 frets. Standard or high frets available.

Finish - the body is sealed initially with epoxy resin, then spraypainted with acrylic lacquer and cut and buffed to a mirror finish. A satin finish is available on request. The top is given only a light coating of lacquer to minimise any damping effect of the finish on the performance of the soundboard.
Nominal Guitar Dimensions
Overall length 1000mm
Scale length 650mm
Fingerboard at nut 52mm
Fingerboard at 12F 64mm
Body length 485mm
Body depth 100mm
Upper bout 280mm
Lower bout 365mm
Waist 245mm

Andrew Knight 1981-

After 25 years as one of Sydney’s busiest and most respected guitar repairers, in 2005 Andrew Knight relocated to northern New South Wales and established a shop in Lismore. Australia.

Andrew Knight has been making and repairing guitars professionally since 1981.

Since 1991 most of Andrew's instruments have been made under the Scintilla label, but since 2012 have carried the “AK” logo.

"I've been a professional repairer for almost 35 years. Guitar-making is secondary to this, but my experience working with them certainly helps understand how to make them. I usually make guitars on commission but, to give folk an idea of what I can do, I also try to have two or three interesting examples in the shop at any given time.
My acoustic guitars have a date on the label (which is usually on the neck block). If the guitar was a commission, it will usually also have the name of the person it was made for. My electrics usually have my name and a date stamped inside the control cavity.

I have used several "Scintilla" logos over the years. All hand-made guitars from 2012 have the "AK" logo, usually as a headstock decal. Some guitars have a bespoke inlay rather than a logo." [Source and image courtesy of Andrew Knight, email 16/1/2014]

The Japanese island of Kyushu is home not just to Asturias guitars but also to the instruments of the secondary brand Kodaira. Secondary? The guitars are built in the same plant, feature the same sublime build quality and the same notable Spanish character. Costs have been cut at a number of points in the production process and all adornments are shunned. This enables Kodaira guitars to be marketed at very competitive prices, even more competitive than comparable Asturias models. [Source: Casabenelly]

Kolaya   Kolaya Instrument Co. Guitars by Brad Daniels. "As with most craftsmen you could assume I'm pretty passionate about what I do. Trees grow in the woods and I turn them into musical instruments. I suppose it's where all of my interests intersect. I've always had a love for wood working and using my hands to create, and I've been playing guitar for most of my life. For my 20th birthday my in-laws purchased a set of indian rosewood and an adirondack spruce top and sent me to my new grandfather, Virgil Shouse, for the opportunity to build my own guitar. As expected I really loved it. What they didn't expect was a total obsession. I continued on with the craft reading and learning all i could and attending the Galloup School of Lutherie to learn what a good fret job and set up looked like. They taught me well as I've been told my guitars are among the easiest playing guitars around. As I continued to learn, my dad supported me in buying materials for me in exchange for the guitar in the end. Much is owed to the people who supported me in the beginning, and I can't thank them enough. " [Source: Wayback Machine]
