I was wondering if you guys could explain to me how send and recieve sockets work when you want to do something like using another external preamp, and just skipping the internal preamp, basically muting the pre-amp. Or something l if I can put my guitar through my ds-2 and use that just as a pre-amp to my power amp section in my amp? Another thing I want to know is which sockets I can just plug/unplug a cable in whenever I want on standby, on, or off.

Hi there.

If you want to use an external pre-amp (Marshall JMP1 for example) and use the power amp section of a head, what you have to do is plug you guitar into the external pre-amp 1st and then plug an output from the pre-amp into the FX Return of your amp head. This should 'mute' the amp's pre-amp and just allow you to use the power amp section of your head.

As far as un/plugging cables in while an amps in stand by, you should ALWAYS have a cable plugged from the amp to the cabinet while the amp is switched on! I think the others are ok to plug in/out while the amps in standby

What Craig said.

Especially the part about DON'T switch your tube amp on without speakers connected, and DON'T unplug the speakers while the amp is switched on.
