apologies, since I'm sure this topic has been covered before (maybe years back in the old forums)...
I use my HD 500 both as stand alone unit for FOH and/or as a straight up effects in front of an old Bassman rig....
When mashing up some new patches for use with my AMP I noticed that the sound of a my tube drive before the an empty amp block sounds completely different

I would expect this behavoir when there is an actual Amp assigned - I don't know why it surprised me that it is occuring when there is no amp in the amp block. I guess I was expecting just a transparent passing of the sound. =
thanks in advance for your input, -Rick
