From the post
Some info about the original:
The Pro Analog MK III is a slight twist on the famed Sola Sound MKII Professional circuit- One of the greatest sounding vintage Germanium Fuzz guitar effects pedals of all time! The ProAnalog MkIII Fuzz pedal features a slightly wider dynamic range between low gain and high gain than the MkII. It is also designed to work nicely in the chain after Wah Wah pedals- something not all fuzz pedals can claim to do. Sweet chewy fuzz with killer sustain that cleans up nice with your guitar volume are the Pro Analog Mk3’s claim to fame.
Each Pro Analog MKIII is hand made with the finest components including NOS Germanium Transistors and Bud Box housings. These boutique Fuzz Pedals feature top notch construction! The main goal of ProAnalog Guitar Effects Pedals has always been pure tone! Not clever names, Fancy boxes, or Gimmicky paint jobs. If you are looking for a no nonsense fuzz pedal with professional quality tone, then the ProAnalog MKIII is the right choice to make. The ProAnalog MK III is one of the best sounding fuzz pedals that we've heard! PERIOD.
Keep in mind this is a Tonebender II variant, so you can try any transistor set that would work in a Tonebender MKII, and give it a try. So keep in mind the gains and leakages. Also, while it's not written in the layout this is an PNP device so if you want to daisy change it you need an inverter.
