I decided to build this and had asked @Robert a question about it and he included it in my next order. This is the newer version with the fix for noise that the first release had. So shout-out to the guy in charge for improvements and being such a generous dude.

I originally built the karaoke chorus which is an adaptation of the ce-1 chorus with some welcomed additions and changes to make it quieter, cheaper to build and more versatile. It did lack the preamp section though. I was on the fence to build this because the first version had noise issues but Robert fixed that and I knew I had to have it for my collection. So what does it do?

It's a very subtle tone shaper, some might say sweetener, much in the same vein of the clandestine preamp. It's not in your face, but it does add a certain depth and dimension to the tone. The high/low input sensitivity switch will give you a very different range of gain depending on where it's set. While many like the drive character the pedal can bring, I prefer it's tone shaping at unity volume. And just like the original, run a buffered signal into it or the impedance mismatch will kill your high end.

The build was standard ppcb fair with great layout and no issues. I had to make it match my karaoke chorus theme and vibe so I went with a match Shang-Chi theme. In the video I tried to show it with and without chorus as it's the integral input section of the original unit.

I like the matching theme thing you got going on. Plus, AIC is always a class act.

Thanks Dave, this song lives in my head rent free forever

Lol I don't know what Alice in chains song that is, but your loop sounds like this to me

I know you don't like AIC but it's nutshell

Super clean build as always too. Your wiring said ((()))

Thanks dude, wiring is life, just like AiC seeing them in 09 before they dropped black gives way to blue at a pop up show in Detroit at St. Andrews hall with no opener. It was loud AF

GD, those look sharp! Love the shared aesthetic. Also, I need that Betty Wont sticker in the background

Where is @Betty Wont ?

Where is @Betty Wont ?

I reached out to Betty a while ago but likely is out living life. Perhaps she had the challenge to be free, like a often do when I dip out for a couple weeks here and there. It's good to disconnect.

Absolutely.

She’s still listing new builds on eBay last I saw.
Maybe she followed Ween on the second leg of their summer tour, and she’s still recovering from the volume, or after it was over she joined a Wook commune in Asheville for a bit

Seriously though, a break from Internet forums isn’t necessarily a bad thing for anyone. The forum will still be here when she decides to come back.

Yours looks a lot cleaner than my build with the "home made" "fix" for the noise.... .
@Robert 's awesome, he offered me a new version board as well, but I decided to go the surgery route instead for the challenge. The outcome is great! No hiss and that lovely bit of harmonic "fatness" it adds.

 

[peccary]

Hell yeah, man - that's a great looking and sounding build.

I really appreciate the way you do demos with a looper, by the way.

I finished this the other week and am getting a high pitched whine with the switch on high; is that what you were facing or a different kind of noise?

very curious what your homegrown fix is!

Not really a whine but more just "hiss". Like a high noise floor. Did you build yours on the latest rev of the PCB? The "fix"is in my build report.

 

[airbud]

hm, ok this isn't a hiss, here's the frequency response on high toggle, with the gain all the way up:


to me that's something different; i tried three different chips of both ICs, no change at all in sound. it's not the end of the world, but it's living rent free in my head.
