Im running guitar rig 5 with a line 6 ux2 into reaper, but the problem im having is that the recording level in reaper is too ridicoulous low, in guitar rig ive set the output level t full and the volume of the amp setting is at the point where its bordering on clipping but still the sound is barely audiable.

Anyone have any idea what i can try ?
Are you sure you are recording from Guitar Rig, and not just the dry guitar signal?

Try adding Guitar Rig as a fx (VST) to the track.
haha yeah cheers man you were right, should of been able to figure that out myself really i just thought guitar rig would be able to record through standalone
