The Dellinger-JSM was developed with Joel Stroetzel, based on the Caparison Dellinger II FX-WM, and is the first Caparison guitar to feature a pickguard. The Dellinger-JSM has a “WM” body structure, which is Walnut on the top and Mahogany on the back, which compensates for the low range which is reduced slightly by the use of a pickguard. The Walnut top, gives the guitar a wide tonal range, from the richest bass to the clearest treble, whilst the Mahogany back sustains and maintains the impressive clarity and definition this guitar delivers. The Caparison Fixed Bridge employs a large movable range for the saddle that corresponds to a wide selection of string gauges and tunings. This is complimented with a saddle lock function to prevent any unwanted resonance and Hipshot locking tuners to stabilize the tuning capabilities. The Dellinger-JSM is fitted with a 5-piece Maple and Walnut neck for increased stability.

The Dellinger-JSM comes complete with Fishman Fluence Killswitch Engage Signature pickups, which pack tremendous versatility into one set of pickups. Voice 1 begins with the Fishman Modern recipe, but Joel & Adam prefer a tighter bass for more note definition and screaming midrange and harmonics. In the bridge, Voice 2 contains an extremely unique vintage/medium output hybrid passive tone, equally great for cleans, crunch, and searing leads, while the neck produces a crystal-clean, fluid voice. In addition, there are unique single coil voices for each pickup, to nail the perfect modern active “hot” coil split and vintage passive true single coil tones. These active pickups are powered by a Fishman rechargeable battery pack, featuring a current capacity similar to a premium 9-volt alkaline battery, which is rechargeable via a standard mini-USB cable.
