I would also add that you need to be wary of buying off eBay as well. Nowadays you just don't know Where the product is coming from. But definitely Amazon is is just filled with Chinese made goods and knock offs. Even if it has a manufacturer's name on it you can't be assured that it is in reality an actual OEM product.Yeah, same question here. My answer was to just buy the good stuff from known supply chains - basically trust that Sweetwater isn't buying knock-offs and avoid Amazon.
I have two of the connectors from Sweetwater that have the brown neutrik ends on them And have had no issues with either my GK amps and cabinets nor
my MarkBass amps cabinets. I also have one of the same ones that are linked above that I did buy off eBay. That also has genuine neutrik connectors.
