Congrats to the team on this! I wanted to make a modern pedal version of the X100 for years but abandoned it when I picked up a used X100 w/RockAdaptor for $150 a few years back.

Based on a thorough search of the forum, a lot of people have run into this issue and it’s most likely the Q2 transistor having too much gain. I’m currently dealing with the same thing on a breadboard because I only had two 2N3904’s on hand, so I’m following the forum advice and trying the...

Bumping this thread because despite a lot of time passing, I'm much closer to releasing my first pedal than I was when I started it. As I type this, the packing and shipping boxes for the first 100 pedals have been delivered and it won't be long before I pull the trigger on all my components...

You’re a prince!

Uhhh…

You can put a non-polarized cap in place of one that was polarized?

These are great ideas! The customer doesn't really care about how the inside looks. Once it's functional again he'll likely either put it in a pedal drawer at home or on his pedalboard. Since I'm about to order the rubber grommet (and some other goodies) from Amplified Parts, should I grab a...

Care to recommend some replacements?

We may have a winner… I probed and signal seemed to flow okay through everything until it got to C3. That’s where the massive volume drop was. I grabbed a 1uf and jumpered around the old one and…IT WAS LOUD! I turned the knobs and they worked as expected too. I’m not sure if everything is...

Last night I went through and bent the legs a bit to make sure nothing was touching anything else. And here's how I have the positive battery lead wired up. I have no idea if that's where it was originally soldered. I see gutshots of other FZ-1A's with the red wire going to the terminal on the...

No, it doesn't change at all as I turn the knob. Thank you so much! I'm dying to get it back in working shape. Already ordered the replacement rubber grommet for the footswitch. As usual, the members of this forum are the best anywhere.

Those were between the transistor legs. With one probe on the battery terminal they read as follows: Q1: E: -0.25v B: -0.32v C: -1.63v Q2: E: 0.00v B: -0.07v C: -1.35v Q3: E: 0.00v B: -0.01v C: -1.60v

Well shit. Guess I’ll start looking for replacements. Should I check the electrolytic caps too? This new multimeter doesn’t measure capacitance apparently…

Forgive me. Let’s try this again. Q1: E to B: 0.227v C to B: 0.221v Q2: E to B: 0.230v C to B: 0.225v Q3: E to B: 0.228v C to B: 0.223v

Q1: 1.41 Q2: 1.41 Q3: 1.60

Agreed. How do I measure the transistors with it?

Coincidentally I also needed a new multimeter so I just ordered one. Should arrive today.

I don't own a transistor tester...yet. Perhaps it's time to invest in one.

Both the cable from the guitar to the pedal and my cable going from the pedal to the amp are working correctly.
