Ruby Mods Question

[Ofek Deitch]

I'm planning on building the Ruby amp soon, and I was wondering what mods are there to do to this amp?
I've heard about the Bassman mod and the 10 x gain\distortion.

If anyone could please tell me which mods are out there, and explain what each one does and sounds like, and if you got some sound clips or videos I'd love to listen\watch them!
I would also love you guys to share with me the mods you have done, and tell me what you thought about them.

Lots of thanks for any sort of help and answers!!
