Title: 999 Chorus (bio77 CS-9)
Post by: Bret608 on May 02, 2023, 01:02:19 PM
So I'm super excited about this build as I've been after a CS-9 for a long time. It's the chorus that a number of my favorite guitarists have used over the years (mainly Bob Mould though). John (bio77) was cool enough to PIF me not only one of the boards he designed and had fabbed, but the delay and clock chips as well. He's also been helping me diagnose what has turned out to be a dodgy FET in the gate section that keeps wanting to randomly get stuck closed (thanks again, John!). Anyway, this sounds seriously good and while not so far off from a CE-2, it has its own thing going for sure. The setting in the picture below sounds kind of creepy, for lack of a better word. I also really like that you can dial in the clock frequency yourself.

Yes it does! Forgot to mention that it's John's graphic, which he was kind enough to share. To me it has that '80s skateboarding vibe in a way.

Sweet!  I gotta admit, I'm a little jealous.  I too have been wanting to build a cs9.  I'm kinda surprised that there isn't a lot of pcbs available.  Excellent looking build!

Aww yeah. Killer build, man.

Is that a pink enclosure? My mobile screen is wiggin out. We need more pink. I've considered getting a second paranormal Tele in pink.

Thanks, everybody! @jessenator--I believe Tayda is calling this color pastel violet. It's really close to the original CS-9 color as far as my eyes can tell.

@blackhatboojum, I know what you mean about there not being CS-9 PCBs out in the world as much as they should be. Check out deadendfx's Mangel Wurzel, though. It's based on the Ibanez RC-99. I probably would have built that had this PCB not come my way.

Same here! Thanks again. I just tried with drive, by the way. You weren't kidding--the gate on this thing is fantastic.
