expydishun Posted March 24, 2014 Share Posted March 24, 2014 Is it true that both outputs on the Spider 3 HD150 head have to be hooked up or the amp will fry? I have read this a few places on the web and I am looking to verify if this is true. Quote Link to comment Share on other sites More sharing options...

Many amps have more than one output in case you want to run two cabs in stereo, but many players (if not most) run mono rigs. What you probably wouldn't want to do is crank it with nothing connected to the outputs. Although how much of a difference this makes with a solid state amp as opposed to tubes, I'm not entirely sure...but all amplifiers are expecting to see some resistance at the back end, so if you if you crank it to 11 with no outputs connecting to anything at all, you might do some damage.
