My Carvin RC 210 & 18 came today and I'm STOKED !! (My wife just gave it loving stares and lots of uh huh's .) Questions to any of you 210 owners out there......Since the headphone jack doesn't disconnect the speaker output is there anyway to practice quietly with this rig ?? Is it safe to disconnect the speakers and run the head that way ?? Please help.......I agreed to sell my other gear when I bought this and it had a headphone jack that cut the speakers.
