Introducing

Kiesel's Offsetof the Century

A true offset hasn't been seen from Kiesel Guitars since the early 70s, marking a triumphant return for the beloved shape.

The Mark 66 represents more than just a guitar—it's a bridge between eras, connecting the raw energy of 1966 with the precision craftsmanship of today's Custom Shop.

"This guitar takes me back to where it all began, but with every modern advantage we've developed over the decades."

— Mark Kiesel

Specifications

Crafted for Excellence

Modern Upgrades

Enhancing overall comfort, the model borrows the top arm contour and tummy cut seen on current Kiesels, as well as the sculpted neck heel and slightly-rolled fingerboard edges.

Standout Pickups

Inspired by Lowell Kiesel's first pickup design, the AP6, Mark Kiesel commemorated his father's idea in the form of the P90 AP90s. For further variety, Kiesel humbuckers are also available.

Three Bridge Options

While the guitar comes standard with a stop tail, players can choose the non-floating Gotoh 510 tremolo or the EverTune, expanding the Mark 66's versatility.

Pickguard or Pickguard Delete

The Pickguard option is standard, signaling back to a classic design, while a Pickguard Delete shows the top on full display.

Scale Length Variations

Available in the standard 25.5" scale length, but players can opt for the extended 30" scale length to suit their playing needs.

Custom Shop Quality

Every Mark 66 is handcrafted in Escondido, California with the same attention to detail that has defined Kiesel's legacy for decades.
