Walrus Audio Meraki Stereo Delay

This thing looks like a beast: https://www.walrusaudio.com/products/meraki-stereo-analog-dual-delay?variant=44470999613675

I'm not familiar with the MN3005 BBD chip, curious if anyone else has built a similar delay.

MBP has a few mn3005 Delay circuits and one of them is stereo although it is a mono input. 8 m3005 chips would be a stupid expensive build that would be almost $100

yeah i remember someone asking about a stereo version of their lore pedal (uses two FV1's in series), they commented on youtube that it would be twice the price if it were stereo.

if an fv-1 circuit is acceptable to you the Binaura is pretty cost effective digital stereo build that has stereo inputs and some the the ping pong algorithms out there are decent, there is also the terrarium that has the potential to be modified to stereo, but that kind of a rabbit hole there.

i haven't checked those out yet, mostly i'm curious about the BBD chip and what people think about it vs others and the PT2399. i'm still learning about bucket brigade circuits.

there are a couple PT2399 delay circuits that sound good in their own right but they don’t hold a candle to other digital and especially BBD delays (IMO)

Delays I know of offhand that use the MN3005:

- EHX Deluxe Memory Man Big Box (and I think the 1100 tap tempo? Possibly other versions in the XO form factor)
- Supro Delay
- Chase Bliss Thermae (and probably one of the Tonal Recalls?)
- Boss DM-2 (but running at 9V)

There are definitely plenty of others, but even between those three there's a pretty wide difference in tone. Everything surrounding the BBD like the filtering and companding and stuff, as well as the number of chips used, are very impactful on the final sound and so the total design should always be considered and not just reduced down to one particular chip.

That said, the MN3005 has twice the stages of the MN3008 and so offers twice the delay time - and, more importantly in lots of designs, stays cleaner longer. That, combined with its ability to run at up to 15V for headroom, makes it a go-to choice for pretty "clean" sounding analog delays (based on demos, I'd say the Meraki falls into that camp).
