Calling all TAPLFO experts, I am losing my mind!!! (Tap-Tempo Cardinal content)

[Cortexturizer]

Thank you for the crystal tester, I will give it a go!

Ninja edit: Dude, don't order another TAPLFO. The chances of two of them being bad without trauma is extremely small.

Brejna told me that he ordered several from another guy from Germany and it wasn't until he got one from the place I just ordered from that he got his Cardinal working. Who knows, maybe some contingent of bad ones got to Germany or whatever...

As for the crystal, I just saw that there are some locally, in Belgrade. Lol. I will go there after work and get me some. We'll know more afterwards.

I really hope it's just the crystal. If it does turn out to be the chip, I'd raise hell with whoever charged you E10 a piece for them.

[Cortexturizer]

Not the crystal. Changed it, and it's the same. Bloody hell.

[Cortexturizer]

Ok, so I thought of the slight possibility that I may have f-ed up something on the breadboard and since I haven't tried the combo of the new crystal and the new taplfo on the pcb at all I tried that and the frickin thing works now!!!!!! It works as it should from what I can tell. Will get back to you guys soon with a confirmation but it looks like it's working well now.
Jesus. Finally

It's always the last thing you think of...

[m-Kresol]

well, that's how it goes. Good to hear you've got it working. Odd that you've got a damaged crystal and chip at the same time. uk-electronic is a good shop for sure. same quality as musikding with fast turnaround times.

[midwayfair]

woohoo!

Kudos for plowing through and not giving up. I can only hope that the design is good enough to have justified the frustration in building it.

I can vouch for it. It is worth it. It's a wonderful effect, Jon. From subtle to choppy. it covers everything.

I think this calls for a demo

[selfdestroyer]

Awesome!

[Cortexturizer]

Thank you lovely people!

I still haven't tried the old chip on the pcb, it might work! If it does then it was the crystal for sure. But right now I am ultra happy to just have it going.

Jon, it sounds pretty good although I am not sure if I have it at it's best still. I have yet to revisit one of your demo videos to get used to the sound some. For now, I was floored by how much difference the Balance and Waveform controls make, I expected them to be subtle but man they can make or break the sound. Is this what they are supposed to be like?

As for the two LEDs, they are 3mm red and green diffused, correct? I don't have 3mm leds right now, only one red so I put one 5mm green in there just so that the effect would work. They have to be of a certain type so that the effect would be at it's best right?

EDIT: Saw your video in the meantime, well mine sounds pretty much like that. Just gimme some advice on the two LEDs and I'll be off to box this baby! Woohoo!

I did notice a bit of distortion on the dry signal, but I think I had volume above unity all the time, and in the Bright mode it's no wonder to have some right?

[midwayfair]

The waveform makes a gigantic difference in harmonic mode. The smooth waveforms are best for that mode. The balance is more for fine tuning in that mode but necessary for really blippy tremolo.

If you aren't using the bicolor LED use red for both (unless they're already soldered in which case what you have is fine). Red/green is just the closest I could get in a bicolor to matched forward voltage -- way better than red/blue for instance.

Great info, thanks Jon. I hope to finish up mine this week also.

Playing with it some more I noticed that my Waveform control only works to half-way up and then after 12 o clock, regardless of the mode I'm in, nothing happens. Is this normal? The pot is a dual B10K pot.

I also biased Q1 to 7.5V as 6V had been giving me distortion on my high output SG pickups. Sounds spongier, not necessarily worse. Will have to spend some more time with the pedal to know which bias I like more.

[midwayfair]

are you getting random mode at all? What waveforms are you definitely getting?
