Cheeeeap! Woah.

Having tried enough flangers by now i kinda get the hype over the chips. Nothing i've tried has stacked up to the SAD1024 and I get all sorts of weird clock noise and stuff with 3207's.
That could be a whole other bunch of things in the circuits but i would definitely trust A/DA to know what they're doing, so i'll probably buy one of these soon-ish.

I think that is more filtering than anything else. I know with my big CCD in the dod 680, there is a ton of clock noise/random artifacts (but it isn't audible at really low volumes or with a lot of sustain...it kinda sounds like old computer chirps/noises...4:43 and after 7:30 some can be heard in this video https://youtu.be/Y9hyYOw_8-U I know that isn't the sad1024, but it is the same mfg and same technology...it's hard to hear. I did hear a good bit of it through my amp, but can't find that in the video...either I cut it or the mics didn't pick it up).

Early bbd delays (like the amdek and original boss, which I believe started as a CCD and transitioned to the bands within its lifespan) use filtering closer to the stuff used on the Reticon from what I've read and they are quieter (and the moog stuff is pretty darn silent too both the clusterflux and delays). Anyway, I think good, quality builds with good planning are the key to noise and stuff and the new ada looks great.

The Reticon CCDs do seem more resonant at certain frequencies to me while also being less "throbby" and more well blended or separated from the original sound depending on their delay time setting. I've read (and can hear) that the delay time will kinda slightly stretch or condense the voltage sample based on length which makes it feel different. The timbre, however, seems more faithful to the original than the dark character of a bbd.

In relation to flangers, I've had (and still have) a few sad1024. I think due to the sample stretching they seem more resonant and effective in a flange setting. I do think that if some of the filtering and biasing techniques (i believe some used some level of high and low pass) can produce a similar sound to Reticon chips...but I still think there will always be something different. How noticeable it would be in a typical mix?

The CCD chip was used in early (and even some current) digital cameras (like space probes and satellites). Those have extra stuff tacked on, but I always thought it would be cool to take the CCD out of a digital camera and process audio with it. To what end, I dunno (I guess to hear what the computer years when processing light?).

The one flanger looks pretty darn sweet.

Double post...board was acting weird.

Sorry for rambling.

yeah, in a mix i wouldn't be fussed about the chips as much as the filtering.
i had a guyatone moving box with SAD1024 that definitely had the same kind of qualities that i liked about the original A/DA but being a more primitive circuit you could hear all sorts of odd artifacts that stick out enough at high volumes that i probably wouldn't want to use it in a band. the A/DA is nice and quiet, somewhat 'transparent' i guess (as much as i hate that word). i think the guyatone is more akin to the original electric mistress.
the A/DA clone i have is (as far as i know) almost identical apart from the 3207's it uses but i haven't looked too much into it. there's a noticeable 'throb' there that isn't on the original that sticks out a bit too much for my liking whenever i pair it with dirt, maybe the circuit isn't tweaked enough to accommodate the different chips.

lg--found your comments on the CCD chips very interesting--may explain my attraction, since they seem to occupy a sonic ground between the BBDs and early digi circuits like the DD2/DSD2, which I'm all-the-time stacking to get a smile-worthy mix.

Back on topic--I'm interested in the cv implementation on these. The 2009 reissue I had was saddled with the OG funkay cv range of +3.75 to +11.25 volts--just made it a lot of work to try to integrate with cv on the pedalboard--tantalizing, because I always thought the A/DA would be particularly cool for some Karplus Strong experiments. I think I read somewhere that the PBF has a more...normal...cv range, but I can't find anything now. Anybody know?
