The Gibson 'Mark' series is an interesting example of Gibson's late '70s period, and of guitar building generally after the guitar boom of the 1960's. As guitars became increasingly popular, many different approaches to studying the instrument surfaced, both in terms of playing and designing. The Gibson MK guitars are the result of the work of Michael Kasha & Richard Schneider, two university professors who became fixated on designing and building the perfect guitar around the principals of physics, eventually partnering with Gibson on the project in 1973.
The resulting guitars features some unique design elements, including weighted headstocks with a counter weight in the heel for increased sustain through the neck, a radically redesigned hybrid X & fan bracing system on the soundboard, and an 'impedance matching' bridge design that tapers towards the treble side. This 1975 Gibson MK-35 is a fantastic example of one of these guitars, in equally excellent condition. The MK-35 features a Spruce top with the redesigned bracing, making it extremely resonant and dynamically responsive. The back and sides are Maple and feature a nice, subtle flame to the grain. The Maple neck has a comfortable profile that is extremely playable, while the headstock features the original Gibson script logo and a set of engraved Gibson tuners.
