Your road trip story reminds me of my own. When I was 18, I saved my money for a year and bought my dream Orange Rocker 30 half stack amp. I ordered online, and they sent me one that didn’t work properly. Rather than shipping it back, I threw it in a friend’s car and we drove to Atlanta (6 hours away) to exchange it in person. We slept in a Walmart parking lot and went to the shop the next morning. They gave us free shirts, an amp cover, and a foot switch. Good times!
To answer the question, my favorite piece of gear is still my Model Cycles. It got me into this world. Something about the simplicity of it…
