PonyOne,
This is a thight, thick & fat tubelike distortion, Hemispheres (HC Forumite from South Carolina with over 6000 posts) can explain you better here:

I received my Ultimate FAT modded DS-1 this weekend and have played it for a little while, but not as long as I would like to yet. First impressions say this is one of the best sounding solid state distortion pedals I have ever heard. I haven't played it enough yet to do a full comparison to my Keeley Ultra mod DS-1 and my Analogman modded DS-1 but I CAN say it sounds absolutely fantastic. The FAT knob on the side is a great addition. So far, I like it to be set at halfway between minimum and maximum. Also, this pedal sounds very tube-like. The most tube-like out of the three modded DS-1 pedals I have (this is with the toggle switch in the "down" position). I played it against a Nady tube distortion pedal I have and my SIB Varidrive and Liys's mod sounds close as far as being authentic when it comes to sounding tube-like (which is amazing for what was originally *just* a Boss DS-1).

I'll be coming back later to do a full comparison. This is just a heads up.

Thanks for the great work. I am very satisfied.
