hi, sorry im asking again by the way: Would it be possible to use both a 15 inch speaker (the current one im using) aswell as a 4x10 cab both with a Trace elliot GP7sm head? its got multiple inputs in the back of the head, ones a 'tuner output!', the otehr two are '8 ohms', one is occupied with the current 15". so as long as the new cab is 8 ohms im fine to run em both togetehr then? cheers! sorry about the question, im useless at technical 'stuff'!
