So I see a guy on a facebook group post if someone is selling a Line 6 M5. I had one lying around, so I responded. We agree on a price and I ship it. I even found the original box with all documentation, etc. The only thing I didn’t find was the power supply. Didn’t think it mattered, as I thought everyone used a power brick on their board. I never said the original PSU was included, but in hindsight I should have told him it wasn’t included. Guy receives the pedal, sends me an angry message how a used pedal should always include the PSU, and implied I was trying to screw him over. So I thought ok, I should have told him about the missing PSU, I tell him he can send it back if he wants and I’ll refund the shipping costs both ways. Then he says he threw the pedal into a wall already out of frustration?! Not sure if that’s true but weird encounter either way. Do you guys generally care if the PSU is included or not when buying used?
