Looks awesome, the white marshall stack is epic!
What is the mauin difference between the 800/900's?
Thanks
The 900 is a standard 900 4100 except it has Ruby tubes in it.
The 800 is actually a Kerry King signature model which is actually a standard 800 bit with the signature Kerry king "beast" assault gate which I never use. It actually has KT88 tubes which the original 800s didn't have.
Without going into the technical details, the main difference is that the 900 has reverb and also has more gain/overdrive.
