The "How many different PLL clones can we get!" Thread

[digi2t]

Sorry fellas. Project has been "boxed", but not in a good way. Everything is literally in cardboard boxes now, in preparation for our move at the end of the month. I'll have to pick this up later this summer.

I did however build a nifty Superfuzz though!



With a really cool sounding 2N2913...



Thems the breaks people. I should be back to the PLL in June, or July.

Ooooooooooooooohhh... purdy!

Good luck with the packing & moving. I was never a big fan of that process, myself. And no worries on the break - we've waited this long for something like this, we'll certainly still be here when you have a chance to get back on it.

Good luck with the move. Hopefully all goes smoothly. Moving's a pain.

Woah, chips? In my Superfuzz?

Er, not mine, per se, just, it's the phrase. But still, woah!

Any of y'all DIY Lords of Badassery make reportable progress lately? Just curious, looking for my fix of sonic amazement.

Im stuck in NYC till Tuesday, once I get home I'm gonna make a layout to do a simplified version. i can't wait! i just need to order the right chips to test at 12 volts, to see what the difference is from 9 volts and then its on. From the bread board, i like probably 4 of the 8(?) selections from the rotary switches per divider and multiplier and some of the other controls will be trims. Can't wait to build this. I can't believe nobody else is reporting any bread board action or builds yet.

Woah, chips? In my Superfuzz?

Big "chip" is a TPQ2222. It's four 2N2222's transistors, in one package. The first pic shows a 2SC1583 dual transistor in the octave section, and the second pic is the 2N2913 dual transistor. The big differences between the 2SC1583, and the 2N2913 are;
- 2SC1583 shares one emitter leg for both transistors (5 pins total), whereas the 2N2913 is two separate transistors each with their own emitter leg (6 pins total).
- 2SC1583 is higher gain (in the low to mid 300's), whereas the 2N2913 is lower gain (mid to high 100's).
Soundwise, the 2SC1583 produces less of an octave, hence chords tend to have less of a ring-mod feel to them. At higher drive settings, single notes will have an octave "bloom" to them as they decay. The 2N2913 on the other hand, provides much more of an octave presence. Chords tend to have that ring-mod feel to them, and the neck pup/tone down action produces a much sweeter octave, especially at lower gain settings. Not quite Jimi on an Octavia, but close. What is really interesting with the 2N2913, is that with the octave balance trimmer I can tone down the octave, and it sounds much like the 2SC1583. Best of both worlds.

This was an experiment really, since I've heard/read talk about using transistor arrays in the Superfuzz, but never actually saw one built and working (insert snide PLL remark here ). I tried two different arrays for the other four transistors; the TPQ2222, and the MPQ3904. As the TPQ2222, the MPQ3904 is basically four 2N3904 transistors in one package. Both gave great results, but the reason for which I went with the TPQ2222 was because of the decay when strumming a chord. It's very subtle, but it produces a much better (for lack of a better descriptor) "shower of arpeggiated notes", as the chord decays. Like I said, it's subtle, but enough to make you go "What the....". I still don't know why it does that, I'm not that technically adept, but my long-shot money is that maybe there's some cross talking going on between the four transistors in the package. Who knows.

Anyway you go, it still produces a fantastic fuzz. Here's the last vid I did of it, with the 2SC1583, in action.

We will now return you to regular PLL programming...

[goroth]

Woah.

Woah for the nice fuzz, the nice write up and the ingenuity!

Picture say 1000 words, yet still make no sound, young Grasshopper.

Am I literally the only person that after hearing demos of this circuit, things it kind of sounds like shit?

i may have something to contribute to this thread shortly.

I love the idea of this circuit and the others like it, but the PLL itself (or the Mini-Ark for that matter) doesn't tickle my ears quite as much as I wish it would. I say this having owned the Mini and having played a PLL in person. I won't say that they sound like shit - they're just not my particular cuppa tea. I think I'd like the PLL better with some filtering though.

That Photonic Superfuzz sounds great digi2t!

OH YEAH!!!!

oh, my.
