The Mod Shop 55 is a customized version of Michael Kelly's top selling 1955 model. This Mod Shop version adds some Lindy Fralin pickups and an electronics mod to the 55's Swamp Ash body, Quilt Maple top, Flame Maple binding and comfortable Maple neck.

On the 1955 Fralin Mod, Michael Kelly went with the most articulate humbucker they've ever heard in the bridge position, Fralin's Pure PAF. Absolutely no "mud" here, the Pure PAF provides fantastic note separation even when moderately overdriven. This pickup matches very well with the Fralin Mini Humbucker, a dual coil hum-canceling pickup with the clarity and "rounder" high strings normally associated with a single coil pickup. Lindy Fralin suggested that Michael Kelly apply a "partial-tap" option rather than the traditional "coil-split" which cuts the output of one coil by 50% when activating the push-pull switch on either of the control knobs. This makes for less of an overall volume drop when splitting each pickup for a single coil tone.
