Before guitars, it was illegal for musicians to take the stage without a powdered wig, and face-melting pianissimos were the only outlet for rebellious youth. Embrace modern instrumentation with today’s Groupon: for $80, you get a thorough, premium guitar set-up at Atomic Guitar Works in Peoria (a $185 total value).

The guitar surgeons at Atomic Guitar Works renovate ravaged axes and restore run-down six-strings to their highest caliber. Prepare your sullied music-maker for an upcoming studio session or nonviolent battle of the bands with a premium set-up, in which instruments are pampered as thoroughly as a prime minister at a day spa. Fret levels are adjusted and re-crowned (a $105 value), allowing swift rail riding and unstymied strumming without heinous lumps and obnoxious buzzing. The lash back for the guitar’s tuning keys is tailored to preferred looseness, and the truss rod is regulated to achieve an optimal bow to the guitar’s neck. Bedridden guitars get their action and intonation adjusted (a $55 value), allowing fingers to dance up and down the neck in tuneful bliss. A complete degunking of knobs, switches, and plugs is polished off with a reconditioned fretboard (a $25 value). Turnaround time is fast, minimizing the wait before guitar players can gleefully renew their vows with their formerly estranged instruments.
