Something like the Carbon Copy

[owlexifry]

Even though it looks like you made a decision, I would recommend my DM-3 as a great sounding delay!

how does one procure one of these DM-3 boards?

I’d like to get my hands on another one or two of those!

Ultimately I decided to go with the Seabed. I think it’s the most pragmatic choice. I’ll save the BBDs for someone who cares.

Does this circuit fix the delay chip lockup issue this circuit has had in the past?

I agree with all the Deep Blue suggestions. It’s excellent.

I made an Fv-1 approximation of the Deep blue delay circuit. The actual repeats are handled in digital, but all the surrounding circuitry that imparts the EQ/tone follows the deep blue circuit. The main benefit for your use case would be long delay times (~1sec) with no degradation. I included the modulation knob which was one of my main goals for the project.

I could probably send you a pcb if interested, but it’s set up for 1590B side jacks.

Thread 'Deep Blue Delay Simulation (FV-1)'

Nov 19, 2023

I finished up a pedal that I’m pretty excited about. It's a FV-1 implementation of the Mad Professor Deep Blue Delay, where the FV-1 handles the delay time and modulation, but the filtering is analog circuitry around the FV-1.

The DBD clone was the first build I attempted, first try (on vero) went in the trash but the second try worked great. At the time, I had read a lot of great things about it and I still do really like the tone of the repeats, which filters both high and low frequencies. It's been my favorite sounding delay circuit, and I'd encourage anyone to build it as is.

I wasn’t aware of that issue- I have no idea. I’ve only built one Seabed before for my bass player, and he hasn’t experienced an issue with it. I did a quick search on this forum, but so far only found mention of lockup in a 2399 chorus Chuck experimented with.

This is awesome. You nailed a sweet spot for a DIY delay.

but it’s set up for 1590B side jacks.

I won’t judge you for it! I still have yet to build a pedal with side jacks. There’s several Madbean projects I’d like to build that are designed with side jacks. I tried fighting one of the layouts, but I think I’m ready to give in and give it a chance.

I don’t remember having this much trouble with finding a good pt2399 the last time I made a seabed.

I have 10 of them here, and I’m struggling to find one that doesn’t have that light fizzy noise on sustained notes, or doesn’t motorboat on the max delay time.

I have a dm-3 board populated, but the “mix” and “delay” controls are swapped compared to the seabed layout. Which means if I pivot that way, I either print another enclosure, or fly the leads.

Maybe I just need to get 10 more pt2399s?

I have 20 each of the SMD CD2399 and regular pt2399 coming from lcsc sometime in the next month (I hope, because I’m moving for July lol). Comparison time! And I can make use of this ridiculous cramped footprint I’m trying out

Definitely interested to hear how the SMD CD2399s work out for you. I wonder if they’ll be more consistent than the through hole ICs?

 

[Nostradoomus]

I'm hoping so, it seems to be the best way as far as QC goes. I mean, if it works for JFETs why not

Also what would happen if I piggybacked the DIP package over the SMD

The TC Bucket Brigade Delay is so cheap, I did not think about building my own analog Delay.

My biggest gripe with all things BBD in diy is most people just leave all the trimmers at noon and say it sounds good so they didn't bother calibrating it. Drives me absolutely crazy. I also vote for building a DM-3. Circuit slays and is dead simple to build and calibrate.

Works on a BF-2 only, pretty much.

The clock trimmer knowing it needs to be set to a specific frequency:

I read that as "dick trimmer" and it still holds true

I’m thinking about pivoting to this. I do want it to slay. He plays in a not-so-obscure band and I want to impress.
