great Job Clinton!

'76 Champ. Love that amp.

to verify functionality and proof of life I use the JMK test rig on my bench, but for actually rocking before boxing I use an actual amp. my new squeeze is a 73 vibro champ that I bought a few months ago. I used to have a 77 champ but sold it and always regretted it. I recapped this one and put a 10" speaker in it.

Anamorph build docs are up. PCB releases tomorrow!

Incredible project!

can also confirm it is an incredible project!

poly chorus is the same circuit as the echo flanger. Follow the bias procedure in the lectric-fx dandy horse and you should be able to get it working, assuming your poly chorus uses the mn3005. Having built the dandy horse myself, it's not too bad.

Resurrecting this one for a qq:

Did you use a CoolAudio THAT2181? Curious how those work out.

I did use the cool audio chip and found it worked just fine.

I've shown this one the past couple build reports in the demo videos so I'll just go ahead and give it a proper build report. I had a previous build report of the Aurum but that was my modified version of the lower gain mode. This pedal is the stock project based on the turbo mode of the OD-2r. The OD-2 was the first all discreet gain pedal from boss and another of the hidden gems out there.

So what's the difference between the two modes? Added gain stage and lower voltage bias for more drive and compression. The turbo mode can do a medium to border line lower high gain sound compared to the low/med drive on the standard mode. This can do some really nice crunch type sounds. It has a nice midrange character but not as pronounced as something like a SD-1.

For the enclosure I decided to take this one in more of a @peccary direction. Aurum means gold and I could have done another yellow drive pedal but went with Melissa Gold aka Songbird (Screaming Mimi) and a cool 80s vibe with lots of pink against a matte dark gray tayda box. All in all it's a nice drive pedal with a nice sound and a different topology and a good build for something a little different.

This turned out fantastic! glad my recommendation worked out for you on the transistors. The lower gain really did sound better in my sound test. Love the enclosure!

<bananas emoji>  Man, that looks awesome!  The surgery looks so clean.  Hats off to you, sir.

Thanks John, I work in surgery so it had to be clean lol

Sounds great and I love the white enclosure! That drive you've been using lately sounds great too. The turbo side of the OD-2, I presume?

Thanks Bret. The turbo mode (mode 2) of the OD-2R is what the Aurum is based on. I did mode one previously which is really nice but I planned on showing this off properly next week.

Thanks guys, I just did the easy part. It's such a great pedal and I'm glad I got to build it.

cool project Bret, sounds really interesting. Any chance o a sound clip?

Oh snap, another long discontinued, harder to find and expensive pedal resurrected from the dead. The Boss ph-1 phaser was one of the first three compact pedals released by boss in 1977 as part of the traffic light series. It was only made for 4 years before being discontinued for the revised ph-1r with resonance control. @szukalski and I were talking about this pedal one day and he decided to take a swing at it and he crushed it yet again.

While it has much in common with the ph-1r, there are many subtle differences circuit wise that give it a different feel and sound. It's a little more basic and simplistic which gives it a slightly sweeter sound and more gentle lfo shape. It's perfect in my opinion. It doesn't get lost and never fully swallows the signal either. It melds wonderfully with drive, especially in front of it, but also sounds good after it. Very smooth.

Now, the original pedal had a volume drop that wasn't as noticeable because of the bypass scheme. When converted to true bypass it was very apparent. After trying a few things with Dave and @blackhatboojum, I consulted @Chuck D. Bones and he gave the clarity and guidance we needed to fix the volume drop. One of the things we tried was half right but Dave set us on the course to success. Man does it sound good too. After a little surgery, no one will ever know🤫😶‍🌫️

For the enclosure I used a matte white tayda box and UV print. I'm pretty proud of this one, the graphic turned out great and really portrays the sound and function of the pedal, Ghost came out perfect. Also used Dave's mini relay board based on Chuck's bypass. For the demo I'm running it in front of the drive pedal for next week's build report, it was also used in the DM-3 demo. This sound clip I made while I was fine tuning the trimmer while playing.

Great job!

Superb build and demo.  The tune's guitar parts really have to be the sexiest Strat-whammy-into-reverb-laden-Deluxe-Reverb ever.  I use the pick plunk over dead strings from the original whenever possible.  It came at an early age listening to Jan Akkerman with Focus.

Thanks Gordo, I was actually using my jazzmaster on this, as much as I love my strat the jazzmaster has the far superior trem IMO

I'll definitely grab one of those boards once you've them in! Thanks for your willingness to do that.

Dan is truly a man of the people. Great guy to work with and his boards are always top tier.

<Mind blown emoji> Really sharp, Chris and the demo slays. 

Thanks John, demo turned out ok I guess, I'm just trying to do them as often as I can since we don't get enough of them in diy.
