After a week of tweaking and swapping transistors, I finally found a transitor combo that got me the sound close to the original 1965 Tone Bender MK1.
A couple of recent videos I made:

Here is the original 1965 Sola Sound Tone Bender.

wow great looking clone! what was the transistor combo, if you don't mind sharing the secret mojo?

Oops....I knew I forgot something..
The winning transistor combo were 2N404 for Q1, Chinese 5N10PC for Q2, and an AC128 for Q3.
Q1: 62hfe, 100uA; Q2:121 hfe, 168uA; Q3: 80hfe, 136uA

How do they look?
Gorgeous build! Nice work
Thanks!! I just ordered two bags of AC125s, hope these wll be enough to make more of these great fuzz pedals.
Nice build.
MKI's are notoriously finnicky circuits, so congrats on building a beauty!
Excellent work, thanks for taking the time sharing it with everyone :)
Nice - both the build and playing.
So far with the 60s fuzzes I've tried, I've found all but the 2 transistor early MK II/FF circuit that bit too thick and synth-like for my tastes. But that MK I circuit certainly has a very distinctive sound. Very cool to see/hear you achieved that without the super scarce mojo transistors of the originals.
Did you make the enclosure yourself? It looks a nicer shape than the originals.
Nice build and great videos!
Bangkok and Working Man, nice!
Great looking build and it sounds awesome!
That's a great sound. Good job sorting through all those transistor combinations, but the final output has at least as much to do with your playing as it does your electronics.

Thanks! The enclosure was purchased from Fry's Electronics and sells for $12.00 USD. The quality and construction of this enclosure is the same as Electro Harmonx classic Big Muff or Small Stone Phaser.
..good video presentation, too fuzzymuff!....hey...may i ask what software did you use for that awesome presentation...nice build by the way!... ;)
