Matchless Independance

actually, matchless impedance = BOOM!

lol

I see what you did there .

Clever, but no...

It's usually much less critical than popular wisdom will have you believe. There are a few exceptions, but generally any valve amp will take a half to double impedance mismatch with no trouble at all, and often 4:1 is OK. It's also always OK if the amp isn't cranked.

But it's still not a good idea to use a severe mismatch (eg amp at 4 ohms, 16-ohm cab) to try to reduce the volume of an overdriven amp, that *can* cause damage.

Sorry to be dull, too good an opportunity to miss .

So if I was wanting to use an 8 Ohm and 16 Ohm cabs at the same time is it possible?

Yes. The combined impedance (in parallel, which is the normal way) is 5.33 ohms, which is safe with the amp set to either 4 ohms or 8 ohms. 2/3 of the power goes to the 8-ohm cab.

Brill, cheers!
