I think, because these are both solid state amps, what you are doing should be fine. If the head were tube I'd be more worried ...

But, either way I would still recommend connecting the head to the speakers; not much point trying to fit a square peg into a round hole. Why not sell the combo and get a proper cab for the head?]]> Live Sound slejhamer https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-348548 https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-348544 Sat, 27 Feb 2010 22:44:14 +0000 Live Sound cantankerousd https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-348544 https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-348541 Sat, 27 Feb 2010 22:37:19 +0000
But DO NOT :!: connect a speaker output to the effects loop jack; it might cause serious problems with one or both units. If the head has only a speaker output, then only connect that to a speaker input jack or directly to the speaker. Set the impedance to match (8 ohms to 8 ohms.) (With some solid state amps you can mismatch the impedance or even give no load at all, but I prefer not to take a chance on stuff like that.)]]> Live Sound slejhamer https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-348541 https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-38561 Sat, 27 Feb 2010 22:18:34 +0000 Live Sound cantankerousd https://guitarnoise.forum/live-sound/using-a-combo-amp-as-a-speaker-cab/#post-38561
