Question:
What will this do? Will this damage the amp/power tubes/transformer? Any "big" effect on tone and/or sound?
I understand that you can run lower rated ohms from your amp into a higher rated ohm speaker/cab, but not the other way around or you'll damage tubes and very possibly your transformer, right?
Sorry if this has been asked before. I did try doing a brief search (not extensive enough, though)!
Thanks for helping the unedumacated!:idk:

Answer:
This has been debated endlessly, but a lot of techs who know their shit would say that you are begging for trouble by running an 8ohm amp into a 16ohm cabinet...and before anyone says that I have it the wrong way around...I do not. I would get the Weber Z Matcher to be on the safe side.

Answer:
Thanks! I just want to play it safe.

Answer:
depends, It's generally ok to do it with mesas though

I understand that you can run lower rated ohms from your amp into a higher rated ohm speaker/cab, but not the other way around or you'll damage tubes and very possibly your transformer, right? Too low impedance, for instance a 2 ohm speaker cabinet hooked up to an amp expecting 8 ohms, will overload the output tubes and the output transformer. The lower impedance will force more amperage through the tubes and out through the transformer. You would get a very loud amp for a short period of time. Something would blow. The tubes probably would go first, but you could also blow the output transformer or the speakers. It is possible that a small power transformer would not take the high amperage and blow up.
Too much impedance, for instance an 8 ohm speaker cabinet hooked up to a 2 ohm Bassman head can be damaging. Mostly you get crappy sound, but there is less danger to the amp. The tubes will operate at higher voltage because the load is not letting the voltage bleed off into output and you might get shorting in the tubes or the output transformer. This is another way to fry an output transformer and it is why you shouldn’t run your amp without a speaker load.

Thanks for helping the unedumacated!:idk: It is the other way around that you need to be mainly concerned about. The easy answer is not to F with it. You will cause the tubes to wear faster and possibly F up your whole system.

Answer:
As long as the load figure is greater than the output, you're safe.
4 ohms into a 4, 8 or 16 ohm cab is ok.
16 ohms into a 4 or 8 ohm cab is not ok.
Impedence mismatches are a greater risk when amps are run near their output limit.

Answer:
I ran a Mesa .50 Caliber head (8ohm) into a Marshall (16ohm cab) for 10 years with no probs.
