After putting the Peavey CLassic 50 212 through an 8ohm load instead of a 16ohm speaker load i can hear a big difference in tone and dynamics. Everything seems alot spongier than before and notes have more sag and are not so muffled and spiky in the mids. Also the lead channel sounds alot better and it sort of sounds like the amp has been pushed more without the volume being too loud, which is amazing. Any concerns please post.
I just selected a dif speaker ohmage and WOW!

Just don't run it past about half on the master volume and you should be okay, in otherwords just don't try to run the amp full out. Clean tones are fine with the master full though, you know what I mean.

Its just the combo by itself but i took the speaker cable out of the 16ohm jack and placed it in the ohm jack on the rear panel of the amp (i dont realy know what that means but anyway). I hardly ever turn the amp up past five on both volume controls otherwise its just to loud on stage for everyone else since its angled up.

Let me see if I can remember this. First of all remember none of this is voodoo it's all math, not all of which I can do though. Everything is done by components and if you are taught what to look for you can even make impedance boxes. The thing I have always been told to remember is that you CAN go from the head to a higher impedance you CANNOT go to lower impedance.
What you are doing by changing the load in this manner is halving the amount of power that gets to the speakers. The way it works is the amplifier expects a higher resistance when plugged into a 16 ohm input so the voltage is higher, but in the lower impedance output it expects less resistance so a lot of power is lost in the form of heat. Cranking might do in your tranny. If it got too hot because it could never supply enough power through that output to run the speakers the way it was designed too. (the inductors and capacitors aren't there to keep the voltage high enough) The 8 ohm out is actually for an extension cab and in most (combo) amps when both inputs are used simultaneously it automatically cuts the ohms effectively increasing output.
Hope that helps
