I have a Torpedo Live on the way and I was wondering if it was safe to use it with a 65' Fender Twin Reissue. The back of the amp is rated at 4ohms where as the Torpedo is labeled a 8ohms.
My advice: connect the amp to the Torpedo Live and you won't have any issue, the amp will deliver less power but Fender are robust and can handle that kind of mismatch most of the time.
