Thats another thing I never understood, Actually i dont understand alot of things because I never dabbled in depth about the dynamics of everything i just played all the time... as many of you have noticed... but anyway, what is the diffrence in having your amp set on 4,8,16 olhms and all of that stuff...

Just set the amp to match the cab you're using. If your cab will let you do both 4 and 16, try both and see if you like one better. Other than that don't worry about it.

 

FYI, the different settings on the amp are just there to give you flexibility with different cabs. It's not supposed to make a difference in tone but people say they can hear a difference with some amps. This is for various reasons related to the different designs but not the reason for the settings.

If you are using a tube amp, most can handle a factor of 2 mismatch without a problem, but it wears the tubes out faster. So, if you have an 8 ohm cab and your amp is set for a 4 ohm load, you are fine, but your tubes will wear out a little faster.

Some solid state amps should never be mismatched. Just read your amplifier and cab owners manuals and make sure to do what they say.

In general, just try to match the amp and cabinet loads.

That's the amount of resistance from your VC's.
