Beatle Juice Fuzz

[Cvp1969]

I’m doing a Beatle Juice Fuzz build now- my initial test has nothing when the pedal is engaged. Then I discovered that I put a 22 ohm resistor at R3 instead of a 220k. I got it off the board and I realize Indont have any 220ks so I ordered a few.

Would that cause no sound in this case or will I have another problem?

Yep, definitely. R3 biases the input transistor.

You could temporarily tack two 100Ks in series just to see if the build works.

It won't be perfect, but it should be close enough until your resistors arrive.

Also, need to insulate the back of that A10k

Yes - I bent it up slightly to insulate down the line. Forgot to do that. It should be interesting that I used a b10 by mistake.. I don’t think I will switch it out.. Internet sez B pots are acceptable for tone control

Thanks.. and.. I don’t even have 100ks! I was trying to fanagle a way to do it with what I have and I just gave up!

And you believed the Internet?

After trying B, try both "A" & "C"...

TRUST YOUR OWN EARS!

Well— linear gain is not all that necessary with tone control… look at the Rat
