very ingenious indeed, hahahaha

It's an almost verbatim Expandora clone... It uses NE5534 instead of LM308

Yes! works great, thanks a lot!

I'm just getting startarted on Arduino, and I built the veroboard and worked great, but can anyone give me directions on how to make the switching faster? I mean, I have to hold the momentary button too long for the pedal status to change. Thanks in advance!

Dude, you're fast!

yes, in the manual says it, they used silicon transistors, just don't specify the model. The folks at Catalinbread use a lot of 2n2222 and BC184, and I think any of those would be a good fit here!

The guys at Catalinbread are pretty cool and published the schematics for the pedal they just released, the Katzenkönig! Sounds amazing in the demos and is basicaly a silicon Tonebender with a Rat clipping and tone section, pretty cool stuff! http://www.catalinbread.com/KatzenkonigManual.pdf The sch...

That's it! MPSA06G for the 2n5089's and BC517 for the 2n5306. I haven't tried it myself, but saw a few guys reporting that the combo solves all the problems (and there's no need for the trimmer, also)

I just saw some reports that the current production units now use MPSA06G and BC517 for the transistores, and a bunch of people reporting that changing the transistors in their clones makes them work as it should.

Thanks for the reply! It's really awkward, and I'm not a begginer, i've been building pedals for some years now, and already checked for cold solder joints, changed the IC, mosfet, redid the wiring, changed the capacitors, triple checked the component values. Dang, sometimes I just hate making pedal...

John K, I built the Trilogic II using you layout, and I'm getting an horrid background noise that I just can't get rid of. Any ideas of what could be causing this? I've been debugging it for a few days now and it's driving me nuts!

pretty neat layout! thanks buddy, I'll try it soon (already made the pedal on veroboard and sounds amazing!)

damn, I've already closed the pedal and packed it to send it back, just have some pictures of the finished rewiring

it looks like this, now

Hey guys, sorry to ressurect the topic, I have one of those to true bypass, and the unity I have here have a LM348N in place of the 3403 and works just fine!

What is this solder pad floating alone on the left, bottom side of the pnp?

100p parallel with the 1M is correct....Nocentelli had acknowledged that error in an earlier post. Thanks, so I got it right yesterday, following the schematics. And I just got the Fat mode working, it was a small motherfuckin' solder bridge, and this thing sounds awesome! Whoa! Thanks guys! :horsey:

Thanks guys! I'll take it apart and check it all over again. I just saw an inconsistence between Nocentelli and jallenshaw's layouts. That 100pF capacitor on the fat side, wich one is correct? the one next to the 2n5089 or in parallel with the 1M resistor? and crw414tele, maybe I'll jump ahead of yo...

btw, this is how it looks

hey Nocentelli, I just built the pedal using your vero, and I can't get the Fat mode to work, I verified the components and the track side lots of times, and just can't get any sound from this mofo. Does your build work ok in fat mode? On the other hand, tight mode sounds friggin' awesome!

I'm a little late do the party, but holy jeebus, his soldering skills are really and litterally da shit!
