From the post
After Josh Homme revealed one of his secret weapons, the small Peavy Decade amp, prices on those sky rocketed tenfold. Deadend Fx just released thier Dekandent project which is based on the preamp section. Not sure how close you'll get to the QOTSA tone but it is at least a piece of the puzzle.
