I need help with speaker impedance. im using a laney ironheart 60w head and laney ironheart 2x12 cabinet. the cab is 8ohm so the cable is going from the 1*8 ohm jack on the head. is this right? because earlier today i was playing and my volume just decreased suddenly and yesterday i took it to the tech to look at and he put it in the other impedance, then back into the 1*8 then it worked perfectly fine but when im playing it now its back to the problem. it isnt a tube problem, ive sorted that part out.

yep should be
If it is new take it back
Sounds like a dodgey output jack or impedance switch. Both are serious faults.
