Well I mean, they literally repurposed the Memphis Phaser board. It's a Phase 90 clone, I noticed that the oscillator is pretty much the same.

This looks like they took the phaser and modified it to do tremolo. The diode is a 5.6v zener I think. It's a 2SK92-N1 for sure.

Hah!

What is this pedal trying to achieve?

I've had different experience, 150-250 hfe is best, octave works here regardless of pickup and tone control settings, down to about the 7th fret. I've used 2n3904, 2n3565 and 2n5172. I prefered the 1st two and they sound about the same, 2n5172 seems not to bias correctly with the original values.

yes, diodes can go bad without visual indication, any part can really

Thank you! I didn't want to pay $8+shipping for it.

Does anyone have this schematic in the OP? I need this one for this revision, but part of the one shown is cut off.

Check the power jack is passing voltage through it as they get corroded, check the zener at D3, check solder joints, check the input jack.

I recently repaired two of these from my own collection, thanks to a post on that other forum by Fender3D. I have cleaned up and corrected the schematic, posting here as well for others who may need it. To reiterate, if you have distortion or other issues replace all the electrolytic caps, 16V caps ...

did you mean 24 volts? 42 volts is way beyond the spec for 2n5458.

Well yeah understanding it is paramount of course, I just see a lot of bickering about it and it gets kind of old. Yes he's current, DC rating and AC rating are different too. Lots of old pedals have 10 or 12 volt ceramic caps, and they can fail. Mostly though it's because they've absorbed moisture,...

ESR, phase shift across frequency spectrum, impedance across frequency spectrum, leakage, inductance, ripple, these are all measurable things. The whole "capacitors are all the same" schtick has been beat to death.

It's definitely worth 32 bucks, I like it, it has nice compression without clipping too hard.

My forum started getting these too (totally and completely unrelated to music, audio or electronics), I think there's a new password db leak.

I have one too, the taper on some of the pots is a bit weird as well. The echo mix should be audio I think, probably a good mod for it.

Also the link in your sig doesn't work.

Nice

Are you sure C10 and C11 are both 4.7uf ?

Strange, have to get the scope out to check signal strengths, or there isn't enough gain to keep the squelch circuit open perhaps.

Did you maybe mix up C3 and C4?

I've uploaded the Mold Spore schematic here a while back; http://www.aronnelson.com/gallery/main.php/v/digi2t/Information/Mold+Spore+Wah/Mold+Spore_schem_smaller.jpg.html?g2_imageViewsIndex=1 It also includes a mod for increased "Straight" output. It helps improve the overall sound of the...
