I got a partial refund on the Boss DR-110 I bought on eBay. The problem isn’t very serious though, a pot needs to be replaced.
I just got the DPX-1 I ordered from eBay, unfortunately in a non working state. The front panel is dented, so someone has probably dropped it during transport. I contacted the seller who had just refurbished it and replaced the PSU. He wasn’t very happy to hear the news and offered me a refund.
If I want my $100 custom fees back I had to send it back. However, the transport to the US cost $150. So I decided to keep it and maybe try to repair it someday. Or use it for parts. Now I’ll have to find another one, they’re not too common.
By the way, I opened the DPX-1 and saw that the CPU was loose. Someone must have dropped it really hard. I put the CPU back in its socket, but the DPX-1 still wouldn’t start.
