I had the problem of changing cabinets on the VST Amp Rack made no difference. Did a search on the forum and found that the install had not copied all the files correctly. So now I have the cabinets actually changing the tone of the guitar as does changing the mic position, but the knob that mixes between the mics makes no difference at all. Does any one notice any difference when twiddling trhat knob, Im thinking I may be missing something else that the install failed to set up.
On 6.5 btw
