John Osthoff has taken all of the disadvantages of a traditional Jumbo–overbearing dimensions, poorly balanced registers, unresponsiveness to light attack–and melted them away from the guitar before you now, until nothing but a smoothly articulate voice and exceedingly comfortable body remains which responds beautifully to a range of modes, from ballad to Bluegrass. Outfitted with a Manzer Wedge, this is a Jumbo which feels much more like an SJ in your arms; you’d be hard-pressed to call these voluptuous curves anything but comfortable. Thanks to a gorgeous, figured set of Koa for the back and sides, which is paired with a Sitka Spruce top, Osthoff’s Jumbo has a bright, dry tonality that’s superb for fingerpicking and lends itself to the smooth balance across the registers. This guitar might be from 2007, but to look at it you’d swear she was brand-new: there are virtually no signs of play wear (aside from the well-opened up voice). Coupled with an Ameritage hardshell case, it won’t be hard to keep it in pristine condition for many years to come.
John's guitars never disappoint! This Jumbo sports some very pretty woods, from the Koa back and sides to the Brazilian Rosewood fretboard and bridge, and the tone is at least equally attractive. 
The thinner, wedge-shaped body of this large guitar makes it feel much smaller. The result is a balanced tone without the overwhelming bass you might expect from this size guitar. The Koa is really beautiful as well. | Scale Length | 25.31 in |
