On the far right is a very unusual and rare 1989 DC127R.  It's finished in Pearl Yellow, which in itself is pretty unusual, but this one also has the "ST" body option, which was only offered for a few years.  Essentially, the ST option was a more rounded, Strat-type body, versus the more pointed Jackson/Ibanez body that was standard at the time.  Additionally, the DC127 wasn't an official model at the time - it was actually a DC125 with a second pickup, in this case, an M22N with the standard M22SD.  Other features on this guitar are an ebony fingerboard, reverse inline headstock, black hardware and Floyd Rose tremolo (which in those days, was denoted by the "R" after the model name; "T" was the Kahler Pro, and "F" was the Kahler 2710 Fulcrum).

Next is a very similar DC200R (2nd from left), also from 1989.  Like the DC127R, this one has the ST body option, but is finished in Pearl Blue with a standard inline headstock.  Other features include gold hardware and abalone block inlays on ebony.  Electronics consist of an M22N and M22SD pickups with dual volume and tone controls, coil splitters, phase switching and stereo wiring.

Second from the right is Kent's 1994 DC400C, finished in Trans Purple on flamed maple with matching headstock.  This has gold hardware, Floyd Rose tremolo, and ebony fingerboard with abalone block inlays.  Body construction is maple neck with poplar body wings.  Electronics consist of an M22N and M22SD pickups with dual volume and tone controls, coil splitters, phase switching and stereo wiring.

Last is Kent's 2005 Pearl White DC727, which was a warranty replacement for his 2002 model.  It has gold hardware, abalone block inlays on ebony, Floyd Rose tremolo and C26 pickups.
