From the vendor
My favourite fuzz. This is a Tone Bender Mk III with a BMP tone control and AMZ blend. The tone tweaks let you dial in some awesome vocal characteristics, or a more modern sound with blend.
Builder beware. This is my best fuzz to play, worst to build. It is a Tone Bender Mk III, read on them. Q1 and Q2 are not too picky. Q3 is going to require a lot of leakage, 0.2-0.3mA. You'll need to have a largish collection of transistors or be lucky with some purchases. Even with the leakage in the right range, you may need to play with different transistors to get the best out of it.
It's also an old school fuzz, so it expects direct interaction with your pickups and needs to be before anything else in your chain.
