Analog Delay

[JustGlyphs]

TC Electronic Bucket Brigade came out today and I think an analog delay would be a fun build. Something weird and with character ideally. No idea how difficult tap-tempo is to implement.

Some options for inspiration: Fairfield Circuitry Meet Maude, Teisco Delay, Jam Delay Llama, Way Huge Aqua-Puss, Mythos Oracle, DOD Rubberneck, MXR Carbon Copy, Ibanez Analog Delay, Boss DM2, Bondi Art Van, JHS Panther Cub, TC Electronic Bucket Brigade (maybe borrow the circuit design but upgrade components?), Seymour Duncan Vapor Trail, J Rockett Clockwork, Donner Yellow Fall

I’m still hoping Robert will trace the Meet Maude or something…

I’ve just started thinking about looking into an analog delay build, and it seems like the thing missing from diy is something really simple like a DM-2 clone, but in 125b.

The DC Echo seems like the penultimate, but has lots of stuff I really wouldn’t need or want in a first try at these.

BYOC has one, but I think it’s 1590BB and side jacks with the enclosure they provide, which is kinda annoying.

The regular DM-2 from madbean looks to be discontinued.

Fun stacked PCB build maybe???

Seems like something great for the PedalPCB treatment!

MB had the Aquababy, which was a DM2. Also the Aquaboy Deluxe, which is my favorite of the analog delays I've built. They are not available now, but if you put out a post, maybe someone sill has a board.

I was going a little buggy going back and forth with the gain trimmers trying to balance things out when I made a discovery. Gain1 and Gain2 determine when and if the feedback knob sends to circuit into runaway oscillations. Instead of using an audio probe and test points, I plugged in a guitar,
I set it to short mode, and turned the delay and feedback knobs all the way up. I adjusted Gain1 until it just started to runaway. Then switched it to long mode and did the same with Gain2. This gave me a perfect level balance across both modes and blend extremes. And it goes into runaway feedback in both modes only when the knob is all the way up

I used this method on mine, worked great. Thanks Betty!

I'm surprised the Diamond Memory Lane hasn't been mentioned yet...

Do you got 30 bucks to drop on BBD's?

So, 45 bucks for used TC Electronic Bucket Brigade was a good investment?
