BassBollocks Posted May 11, 2012 Share Posted May 11, 2012 General tech question: I have a Fender Rumble 350 Watt head which I use with a Marshall 1540 4x10 cabinet (and it's a great combination). Now I've always been very careful with separate head/speaker cabs not to turn on the power unless the cab is connected. I understand that if I were to do this I could damage the amp as it sees no 'load' (this may be more relevant to valve amps, but I always take the precaution anyway). When I plug in my headphones, the speaker cab is, of course, bypassed. Am I correct in assuming that the amp now sees the headphones as a 'load'? Am I also correct in assuming that I can safely disconnect the speaker cab and utilise the ultra-portability of the pocket-sized Fender with just my headphones connected?

Graham Posted May 11, 2012 Share Posted May 11, 2012 Am I right in thinking the Rumble has a solid state power amp? If so don't worry as it's only valve power stages that always need a load. Quote Link to comment Share on other sites More sharing options...
guildbass Posted May 11, 2012 Share Posted May 11, 2012 No amp is happy without a load but headphone sockets usually switch out or at least provide a load for the output stage. Quote Link to comment Share on other sites More sharing options...
BassBollocks Posted May 11, 2012 Author Share Posted May 11, 2012 Thanks guys... I thought this was the case but I just wanted to make sure - and yes, Graham, the Rumbles are all solid state. Quote Link to comment Share on other sites More sharing options...
