Foxey Fuzz (Tone Bender MKI.5 on stripboard)

[Guilherme Collateral]

Here is another mojo-tastic build. Used a pair of Tungsram AC128 for this - I hate this transistor on Fuzz Faces, but sounds great on a I.5!

And a short video showing its clean up:

Ooh I like the fake out with the volume. Sounds great and that clean up is amazing! And as always, an astoundingly beautiful build. Good stuff!

I agree with you about AC128s on a TB circuit. I used one in my MkII build and it sounded great. This one looks like a winner!

Thanks a lot man! Glad you liked it

I’ve been building pedals for almost 20 years and for some reason I never built any MKII with AC128! I’ll try it this week

I used it for Q1 but overall, it was a mix like the MkII you just posted. I had AC125 for Q3 and a random 2n217 in Q2. I think Q1 has a big influence over the sound, so you will probably like it! I need to try a MkI.V like you have here--I've done a straight Ge Fuzz Face but not this one!

I really recommend it! But don’t use a transistor pair you would use in a fuzz face, it needs lots of leakage to sound as a real deal MKI.5. You want low gain and high leakage! Check the voltages online

From what I've seen high leakage (>100uA) gives 7 to 8 volts on Q2c and that makes it sound crispier than a Fuzz Face.

This one sounds dangerous! Great work!
