Previously I was not convinced when using the green scream. Seemed something was not the same as my Maxon pedals. I discovered that if you turn the drive up just a little on the Kemper version it gets very very close to the real deal.
Here are three samples. 1 unboosted, 2 boosted, one with green scream one with Maxon OD808x.
Which is which?
