So today I bought a Satchurator pedal to replace the distortion in my Vox Tonelab ST. But I haven't been able to get a tone that was better than god awful. I'm playing the pedal straight to my Behringer AC108 vintage that I got from a friend who didn't play it anymore.
Does the bad tone come from the old amp or is it just me who can't set it up right?

I'm trying to get a tone similar to this: http://www.youtube.com/watch?v=e-OK7sS855M

But instead I get this whatever I try: http://www.youtube.com/watch?v=v1qUL8KSqAY
