Owners highlight the exceptional comfort of the Kiesel Lightspeed, noting it as the most comfortable guitar they've ever played.

Long-term players, with over 35 years of experience, find the Kiesel Lightspeed perfectly suited to their needs, reinforcing its tailored appeal.

Owners appreciate the raw tone finish for its protective qualities and the natural relic look it develops over time.

Some find the Vader's unshielded fine tuners prone to accidental bumps, impacting tuning stability during play.

The Zeus's lower horn can dig into the thigh when sitting, a comfort issue noted by some players.

The unique Royal Ebony fingerboard is praised for its aesthetic appeal and feel, with each piece being distinct.

The Quilted Black Limba top is a rare feature, as quilting in black limba is uncommon, adding unique visual appeal.

Despite price increases, some owners believe Kiesel offers good value compared to other custom shops, like Mayones, which can exceed $5,000.

A comparison to Strandberg indicates that players who prioritize ergonomics might find the Lightspeed a compelling alternative.

Owners compare the Zeus and Osiris, noting the Zeus's down-turned horn is better for sitting, while the Osiris's longer horn offers a closer nut position when standing.

A 3/5 way blade switch can be requested as a custom option, providing flexibility beyond the standard 3-way toggle.

Weight is estimated around 6 lbs, contributing to the guitar’s comfort and playability.

The extra strap lock on the Vader is designed to protect the finish when setting the guitar down, although some find it visually unappealing.

Raw tone finishes are favored for their open grain and slight durability over tung oil, although tung oil offers easier repair.
