Up for sale, a 1975 Gretsch Roc Jet model 7613 in perfect working order. Produced from 1969-1976, the USA-made Roc Jet features a pair of Super'Tron humbuckers, representing a modernized spin on the classic Duo Jet platform.
Tonewoods include a chambered mahogany body capped by a bound maple top, paired with a rock maple neck and bound ebony fretboard. Acoustically, this guitar is rich and resonant, with the glassy articulation and immediacy of the ebony fretboard and the bark and breadth of the chambered mahogany/maple construction. The original pair of Super'Tron humbuckers feature laminated steel blades in lieu of individual pole pieces, and the larger magnetized surface area produces greater inductance. More aggressive sounding than a Filter’Tron, the Super’Tron offers broadband punch, delivering chewy twang in the bridge position, and a thick, warm quality with a bell-like response at the neck. This Gretsch weighs 9lbs 5oz, professionally setup here at Mike & Mike’s Guitar Bar with 10-46 strings, low action, and accurate intonation.
The maple neck has a slender C-shaped profile carve with moderate shoulder at the nut and a hair more overall heft further up the fretboard, measuring .760” deep at the 1st fret and .905” at the 12th. The bound ebony fretboard features pearloid thumbnail inlay, refretted with flawless medium jumbo fretwire, including a new zero fret. The neck is straight, and this Gretsch plays cleanly in every register up the 24.5” scale with an optimally-adjusted truss rod. The fretboard width is 1 9/16” at the zero fret, just forward of the original nut. The headstock retains the original tuning machines which turn smoothly and hold accurate pitch, with clean chrome plating.
All of the electronics function as intended, with the Super'Tron pickups wired to the stock harness with untouched solder joints, governed by a three-way pickup selector switch, Individual Volume and Tone controls, and a Master Volume knob on the treble-side cutaway. In the control cavity, the original serial/model label is intact, dating production of this guitar to April, 1975. Hardware includes the original quintet of machined aluminum G arrow knobs, a modern floating Space Control bridge with rosewood base, and a G trapeze tailpiece (also modern). The original, and remarkably clean, raised lucite pickguard rounds things out.
The gloss Walnut finish on the maple top exhibits vertical finish checking, framed by multi-ply cream binding. Cosmetic wear includes buckle rash across the back, and a number of dings and chips on the body perimeter. The top, in comparison, presents quite well, with just a few tiny nicks and faint finish scratches in the clear coat plus some finish loss beneath the feet of the floating bridge. The neck profile retains its smooth gloss, with a couple small nicks on the bass-side shoulder behind fret 4 that have no impact on playability.
