the Soothsayer uses a real-deal new-old-stock LM308 chip—the same one used in the original "whiteface" units that are worth an arm and a leg today. However, basic topology and IC are where the similarities diverge between the garden-variety rodent and the Soothsayer.
As far as the sound is concerned, imagine the sweetest, most transparent overdrive on the market. The sound of the Klon needs no introduction and thus, neither does the Klone V2. It's voiced so accurately that one would be hard pressed to tell the difference between the Klone V2 and the real deal.
The Analog Alien FuzzBubble-45 is a fantastic dual pedal that features a vintage-voiced overdrive and a fuzz face in one box. Not only will the Analog Alien FuzzBubble-45 channel Jimi and Pete but it will provide more versatility for a plethora of tones.
