Interested to get some feedback here. What if I were to move the next Dirtbag to a 4x BBD rather than a 2x BBD? So, you could use (4) MN3005 (for 1 second delay), or (4) MN3008 or BL3208 (for 550ms delay)? Would this be worth waiting just a bit longer for the project? It would move the project into probably August.
What do you think?
Could you do both?
Hmm. Not at the same time. Obviously, I can do DB2 now since it is already planned. To do DB3 (?) at the same time would probably push it even later in the year due to the cost of manufacturing. DB3 would probably be closer to a $20+ board. I am a little reluctant to spend the money manufacturing DB2 if what people really want is DB3, hence the general question.
I already have two mn3005s on hand waiting for the release of the db2 so I'm biased. Otherwise I would probably be perfectly happy with the db3
Would the BBD's be individually biased like the 4xMN3008 reissues? It would be nice to have something like that so people could use a single 3005 and three 3008's, 4x3008's or something if they can't find pairs of 3005's and don't want to mess with daughterboards. Honestly, I will buy the boards no matter how they come. DMM=magic.
I'd think the 4 X 3208 option would be better in the long run and have broader appeal. They're $3.50 each and easily attainable. Everyone could build one.
Highly agree with 4 3208's
I'm a little bit bipolar about that question. On the one hand, I'm anxiously waiting for the DB2 and would really like to build a proper MN300x version of it if I find some decent ICs. I guess the 4 BBD version will be even more appealing to some people since it has more options but it will also be a question of costs when you want to build the MN version. Those are costly!
I'm good with whatever you'll do in the end and grab one for sure.
I vote for the 4 x chip version, sir.
I have no holy grail 3005 ICs in my component stash and am far more likely to take on the project if I can obtain its components within a reasonable budget/timeframe. I guess I'm not alone in that.

That would be my prefered option as I have one 3005 on the way. But I could live with 4 3008's as well.
And as usual i'm assuming that upcoming in august actually means somewhere in october at best? ;) Just like the current scheduled releases for june aren't coming this month either?
4 x 3008's definitely. 3005's are just not worth trying to source. What about making a delay specifically for the v3205? Without distortion of course!

If you go for 4 x 3008/3208 it'd be perfectly simple to just jump 2 of the BBDs if you didn't want to use them so it makes much more sense in the long run for both 08 & 05 users.

My thoughts exactly.

I have two 3005 waiting for db2. But if made for 4 chips, well, probably as someone said, jumpers will be a solution to keep both 3005 as 3208 owners happy 😺

In that case I'm in!

That sounds like a really fun idea - to be able to mix & match!
But yeah, with 3005's getting so scarce, I would think going with 4 chips is a better option.
4 chips for me for the same reasons listed above. I've been put off the 3005 designed boards due to price and availablility of the chips. If you design the board with more affordable and available chips then I imagine in turn you'll end up selling more boards.
another vote for the 4 X 3008/3208
I vote for the 4 chip version. I've been anxious for the June release but I'd much rather wait for the 4 chip version.
I think the 4 chip version will make the most sense.
If you already have the 2 chip version designed and verified, maybe a small batch run will sell to folks that have MN3005 chips and then you wouldn't be burdened with keeping an extra SKU in stock.
i would be interested in the 4 chip version
I also say go 4 chips.

I have 2 3005s, so the 2 chip version would be my choice. A small run of those would be great. I get the appeal of a 4 chip version, but I don't have access to a scope, so the calibration would be a nightmare.
I've been eagerly waiting for the next incarnation of the Dirtbag since the end of 2013. It's definitely the build that I've been anticipating the longest, and honestly check the projects page several times every week to see if there's a new status.
That said, my plan was to use 4 MN3008s with an adapter board, assuming that it was a 2 BBD design. So as much as I'd like to vote for the more immediate result, I think I'll vote to wait as well. I'm sure the 4 BBD integrated design will be a much cleaner build than the original project I was envisioning.
TL;DR - 1 vote for 4 BBD design
I have a nice stash of 3008 waiting for just this. I also have the adapter boards but if it was made for 4 chips id be elated.
I'm working through the layout now. I'll update you guys on the progress. Not to worry-- I won't let this slip by. The Dirtbag is going to happen and soon. But yeah, let's make it the absolute best project we can. Also, I'll be adding a Rate pot for the LFO for an extra modulation control.
I got a 3005 stash, but as long as I can use them for the DB3 also, I don't mind waiting a little longer!
4 bbd.
Just the rush from the dirtbag customers would send prices up further. and I am stressed by any part that is being counterfeited.
It took a couple of days, but I am pretty happy with the layout. I'm doing the final checking over before submitting it to OSH Park. I'll be experimenting with mixing MN3005 and MN3008 on this.
Wow. Awesome. I have 3xMN3005, and 3xMN3008 hanging around in the parts stock right now and all of them just jumped for joy! If you need a second verifier...
I would totally volunteer to beta this one as well.
*pants have just been creamed*
Do I see this correctly that you can basically use various combinations of 3005's and 3008's?
I was going to use v3205s, but everybody agrees that BL3208s sound better than the coolaudio stuff, so the 4 chip way seems appealing for those taking the "cheap way" too. Or use 4 v3205 for double the delay...
I hate to wait longer, it's true, but I guess I can build something else in the meantime :). I hope the result will be worth the wait!..
I have 4 x MN3005 and 4 x MN3008 if you need testers also

Seems like a longer term solution.
Spoiler: noob question alarm!
I haven't build any pedals using MN3005 nor MN3008 yet, so I wanted to ask what the most obvious differences are, where they are generally used, where you get them from and what a fair/regular price is these days.
Thanks!
There is a good summary of the differences between BBDs on page 6 of this doc.

Thanks. That helped me a lot!
I also have 2 x MN3005 waiting for a Dirtbag. Perhaps a short run of the original Dirtbag board for those of us who have been waiting?

I'm in... For days i've missed the 1st dirtbag board...
Steve just got in a ton of v3208 chips at smallbear which have apparently been QA's. So, I will be testing these in the DB3 circuit, too.

They're the 8 pin format not the special 8 (14 pin) format though?
