Congratulations, you found the first typo in the manual. SIR is another plugin, RIR is what's inside Revalver. I will fix this asap.
what about the crunch and distortion knob? did you turn both down when you demo'd revalver and did the sound improve or did it totally mute it? you might want to check into that too....because as i said before mine mutes
I love the pictures in the manual espacially the guitar you choose! great.
@KAzrog
what happens if I delete the files and want to download them again AFTER 72 hours?
Revalver shouldn't mute the sound if you do this. That is very strange, definitely not what was experienced in testing here.
