Hi,
I'm also having the same problem as the OP and I've replaced the BBD chips already but that hasn't resolved the issue. When the chorus is turned up and I'm not hitting any notes, I can hear a pulsating white noise so, suspecting it's the signal relay, I popped the top off and applied some deoxidizer to it. Sadly that hasn't helped either, so I am now looking at replacing it. However, the part (an Omron V2G-2-DC5V) is no longer manufactured. Omron do currently sell a V5G-2-DC5V but I don't know if it is a good drop-in replacement since I can't find the datasheet for the original V2G-2 anywhere. If anyone here has that datasheet, could they kindly please share it or just confirm that the new V5G-2 works? Thanks in advance!
