Hi Haradax,
Nice layout! And thanks for updating.
I've not done anything yet to my build

Regarding the component values - did you use the schematic ones or the from the layout?

Hi Mecmast,
I've not solved the issue with my build. It is still as it is.
You could try building it. Perhaps it is an error in my build, and you could make it through fine?
Go for it!

I remember reading about this, and did a search here: viewtopic.php?f=7&t=713
PT2399 Pin 4 should be grounded - should solve this problem.

Hi everyone. Some updates on this. I have built this according to the layout (not the schematic values, refer to notes): 1. 1K8 on layout (vs 1K on schematic) 2. 100 on layout (vs 100K on schematic) 3. 33uF capacitor polarity (polarity follow schematic, not the layout) 4. 47nF cap connects LM324 pin...

Hello everyone. Yet another revival of an old (and possibly uninteresting) thread. I was comparing the Sprint layout by makrz which was re-upped by gena_p1 against the schematic ( uncleboko / analogguru ): https://www.freestompboxes.org/viewtopic.php?f=1&t=3567&hilit=13600#p38758 I noticed f...

If this is supposed to be a "Brian May tone" pedal, why does it have an analog of the Top Boost tone stack? Brian May doesn't use the Top Boost, he plays through the Normal channel of his AC30s. This is not a knock at the work done by our friends here who have cracked the circuit, but que...

Thank you Sir!!!

My ordered pots have arrived! Just another 4 days to go till weekend...

Hi tonymccbony, I happen to be building the YDR right now(!), based on the schematic by GGBB: http://www.aronnelson.com/gallery/main.php?g2_view=core.DownloadItem&g2_itemId=47993&g2_serialNumber=6 I'd greatly appreciate it if you could confirm the C13 value. I've decided to pop in a 1uF ther...

Thank you Dirk

Hi friends, was sourcing for LM308N for the ultimate Rat build, and came across these: Questions:
1. Can I trust those LM308Ns? They 'look' suspect
2. Is the CUE LM308 good for a Rat build?
3. Is that LM3080N a CA3080 equivalent (can I use in a Ross compressor build)?

Hi friends, I would like to get some 1290NS enclosures. I like curves :oops: Also, I have 3 unused Hammond 1590BB that I want to get rid of. 2 are in their original packing, and 1 with sealed removed and with drill measurement marks (planned to use it, but decided not to). I don't mind trading with ...

My orders were all shipped from Hong Kong.
Never had a problem with them or the quality of the stuff they have.

Does anyone have any idea whether or not this is a fake or the real deal? IMG_7538-1.JPG IMG_7539-1.JPG IMG_7540-1.JPG IMG_7541-1.JPG I hope it is the real deal, it is the most expensive component I have ever purchased, at USD 5. I stumbled onto this part (I do not have any interest in modulation ef...

Thanks jymaze!
Guys, I didn't do anything but just edit Madbean's schematic to reflect jymaze's mods.
Credits to jymaze, Madbean, CultureJam & everyone who has contributed in this trace.

Here's the same schematic, without the injured R2 (sorry about that):

I believe this schematic is correct to represent jymaze's Uproar:

Guys, I have found a local store, which has AC128 in stock! Obviously they are NOS, and qty is my guesstimate of around 50pcs or so. Anyone could guess the retail price?? Here's something you should factor when guessing the price - they do not know that us hobbyist-stompboxious are looking for these...

You've got steady hands!!! Fantastic crisp pictures there!!!

Dear Lance,

Are these devices original designs or lifted designs obtained from this board? It's a fair question I think. Is it that you share ideas but don't sell designs shared here with the general public for financial gain, or do you have a company that builds and sells the designs of others? If you do lift...
