Love Letters

‘‘ WOW!!! I WON, I WON. Gearnuts kicks a**, I can't believe I actually won the January giveaway, a beautiful EG-1 Traveler Guitar. Got it fast, unpacked it and after very little tuning it played great, I love it and need it, Perfect. Thanks again I am a repeat customer and will be getting a Gibson real soon from you. ’’ – Earl Snyder, Miami, FL

Earl, you're an inspiration to everyone who says they never win anything! (Except the Crew here at GearNuts, because we're not ALLOWED to win any of our contests. Sigh.)
