Thanks for the tips folks:)
Yes I have the cab hooked up (I was warned before I left the store with this puppy:).
I do understand about the audio differences with this option, but my problem is that it sounds too way off from a decent guitar amp sound. Sometimes it sounds like an AM Radio losing signal:P
The heads fine on its own. The Mbox seems fine with mics and trs cables straight from instrument.
Also, I live in an apartment and no I cant turn it up as loud as I should
I guess Ill venture into adding Guitar Rig to my mini-studio:)
Thanks again guys for the help:)
