The Sounds of Today is Ian Sherwood from Ghost Effects adaptation of the MKI Tone Bender.  It’s all explained by Ian here, with photos.  There are also plenty of photos of these in various stages of construction Instagram too, so you can see a few variations along the way.

Short story: The attack has been replaced with a fixed resistor.  The resistor in Q2 collector is now a bias pot, and the drive pot restricts the level into Q3.

As you can see, there are a few unknown values – and if you build this kind of thing, I’m sure you will be confident enough to try a few things and work out what you prefer.  It is an MKI after all, and these often take some tweaking/transistor tests to get sounding good.
