If your after a exact copy of Davids classic Dallas Arbeiter Fuzz Face. Then check out the Analog Man Sunface its the closest to Live In Pompeii you will ever get.

For more classic tones like The Devision Bell and Pulse, On An Island check out The Sovtek Russian Triangle Muff..... Brilliant Pedal.

Good to be back after a relative while of silence! I lust after the analogman sunface. but it is waaaaaay out of reach. i recently tested the Morrison Big Fluff at a music store and i will give a quick review

pros: Brilliant Gilmour Tones! ranging from mild "Dogs" tone to screaming "Time"
cons: A lot of excess noise. but i think this will go away when your amp is cranked. did well on the roland cube i played it through
