How to build a Spring Reverb Module 

you have to change your title because it's not exactly about "how to build a spring reverb module". Especially that you're actually bought all the components and soldering it in fast-forward video. The video quality is great, but the information is a bit misleading :)

*please* make more videos man! found this via synthtopia and it's gotta be one of the best eurorack "build" videos i've seen in a while-and it's actually entertaining. great vibe and quality work in general as well. big up man.

the way you speak makes it sound like you're solving a crime in an old movie

I found this as I am looking at building an actual spring reverb with tank. I would love to have heard what this sounds like with a real tank attached to it.

Love your fume extractor set up with the hose, very clever.

Cool workshop you have over there, neat and organized!

sick jam, dude! That reverb and your sound is great!

Clear explanation, awesome production quality. Subscribed!

Really nice video and demo!

Great video - very watchable. Thanks

Awesome, that will be my next build after I finish the Turing Machine. Thonk really is an awesome shop

Subscribed because of this video. Good work.

Seriously loving you background music. I am back at PS1 Ridge Racer 4. Very cool

Great work Leo!

The tanks are actually pretty tough, or used to be. The 66 pontiac i had came with one as an option for the radio bolted to the rear deck. Worked well into the eighties til the old caps went out and fried the transformer. Some plyers smack their amps to make that crashing sound . Have fun ! Try cascading a few of them it siunds like you're in a bottomless cave

This is an awesome video. I def. have to say that it would have been really nice to hear this thing actually run through the revery tank that you showed. It's still a cool video. But... yeah... feels a little click-bait'ish since you kinda... didn't build a spring reverb module, but just a... reverb module. Again... still cool.

Beautiful sound

This is amazing!

Loving this!

Love your video, very professional! Curious how I could power this on its own? Like a stand alone unit that O could use as a reverb send from a studio console. Would I just need a cheap-o wall-wart that’s 12v and connect the positive and negative leads to the right pins on the unit? Sorry for my newb question I’m just really looking at building one of these but I’ve never dealt with power supply stuff (I’ve only built API lunchbox 500 series audio units). Your response will be gold! Thanks and cheers

Great video. Makes it 👀 fun to build and play. Was on my list and just went up it a couple of places :)

Great video. I've built a few of the earlier version of this module, it's great. I haven't bothered with the digital tanks yet, but maybe I should, it sounds better than I'd expected. The user manual for the Intellijel Springray (version 1) has a bunch of good patch ideas. One of them is sawtooth vco => filter => => vca => reverb, and use your vca envelope to also control the amount of reverb feedback. Set long-ish attack/decay... can sound very much like a bowed instrument

Loved the background music you had when you explained the tank. Is that your tune?

if your reverb is picking up electrical noise then make some shielding for it. a metal box (sealed all the way around) and it must be earthed. that's all.

you can solve the spring disconnection problem by taking needle nose pliers to the hooks on the ends of the springs and bending them closed. though that will not eliminate the accidental stimulation of the reverb if you bump the unit as the springs can pick up that. also if it is mounted in the speaker you can get feedback thrugh it if you have the speaker too high

Great video man, what brick decay length did you go for?

if it doesnt have a spring, is it still a spring reverb? one of those great philosophical headscratchers, ey, nudge, nudge? cool video and cool verb! did you ever try the blending option between tank and brick?

Great video! Pity you didn't try to modulate the parameters on the Spring Reverb module.

Awesome vid. Which tank size is that? thanks

Love that Grand Tour poster! (ePBT?) Noice beets, noice voice, noice d...doicumentation.

physical spring tank is better because you can slap it to make thunder sounds

Cool...thanks...

Hey I was curious, how do you amplify your actual spring reverb? I purchased a spring tank for a guitar amplifier with the intent to use it as a reverb effect for recording. I quickly realized it needed a preamp at the end of the signal because of the low output, and I purchased a Velleman universal mono preamp kit, but tbh I don’t know enough about PCB work yet to completely understand what I’m doing. Any help would be appreciated!

This is nice

What sort of projects should you start practicing with before doing this module? Thanks

Yo dope video. I’m looking for a desk/fume extractor for solder work and I was wondering what your setup is

Great video! What is the total depth including the brick?

This is very cool but I have a couple of questions. First, my reason - I have a guitar amp that I put together from a Hafler tube guitar preamp (awesome) and a power amp that it feeds. The Hafler has an FX send and return, which I believe are line-level. I also have a MOD reverb tank, inexpensive and still very cool. I need to build an amp and return that can take take the FX send of the Hafler as input and then output to the Hafler FX Return. My questions: 1. Not all of your knobs are labeled. Is there a dry/wet mix control on it? I would need to pass the entire signal through it, so I would need to take the mix down to about 20% or so. 2. How is the kit powered? I'm not knowledgeable about Eurorack stuff. Could it be powered by a wall-wart style power supply? I've got tons of them, going all the way up to over 30V and 4 amp. If it can be powered by a wall wart, I'm sure I have one that will work. 3. I'm a little insane when it comes to digital latency, not only can I hear VERY low latency amounts, but they drive me crazy. If you pass a signal through this kit with the reverb mix turned all the way down, is there any measurable latency at all - i.e. is the mix path analog or digital? If the entire signal goes through any digital device, there will be some latency. Thanks!!!

So with the right patch bay could you use this in a traditional outboard gear studio setting? Or is it best just used as a synth module?

Hi, I’d like your advice... (today) I’ll be purchasing a used Empress Reverb pedal for $450 did I make a good move or should I just pick up a soldering diy kit/station

Smart, a shop vac fume extractor!

Is it the small / medium or large reverb brick please? I want to buy one but I don't really know wich one to use, the one you've got is quite nice sounding :)

Was that one of the Milton/Janesville Wisconsin spring tanks?

spring reverb is used in gear taken on the road by bands and tossed around. I think you'd have to drop it from a plane to get the springs to pop off

Besides the excellent video, that Microbrute is pretty impressive!

Hi, what fume extractor system are you using?

Not a spring reverb without a spring!

haha i don;t think you should be too worried about the springs coming loose. dub soundsystem guys sometimes drop their reverb tanks for effect hahaha

Are there any Strymon Reverb DIY kits out there?

How about a reverb unit that's small enough to fit in a pedal?

Do you need a modular to do that or I can plug in to a hardware synth ?

why does this sound like a darker version of "safety dance" to me ?

Sorry you had so much negative comments on this one. But I agree the video is misleading about the building part. As for demonstration, it was more on "how a reverb can better your sound" than, what I would have expected, on how this reverb really sounds. How long is it reverberating, how big can it get? The way to test a reverb, from my knowledge, is by playing short percussive sounds to hear it's color, attack and decay time. I spent 15min waiting for it.

Can you smack it and it will go "splashhhh"??

beef a co spring reverb module?

Sound track title?

So all that to create a digital approximation of a spring reverb, which is already in every software out there? What did I miss? You have a nice tank in your hand... this feels like mounting a digital plate reverb module to your Ikea shelf after doing all the work to build it.

Not actually a spring but uses a Belton/Accutronics reverb module. It uses 3 pt2399 delay chips that replicate sound of actual spring. doesnt sound exactly like a spring but really close.

Can’t you just put the accutrinics dsp chip in the Belgians place

This is the first time I've heard someone saying "this is digital, so it's robust". As a software engineer, I find things to be quite opposite. I have, on the other hand, no issues with my actual valve-operated spring reverbs that I thrash around in my guitar amps.

I thought this was gonna be a real spring reverb tank, but it's just a Belton brick

hey.. another nasa JPL poster haha. i have a few of them i like my grand tour poster

lol. worried about a spring verb. man. guitar amps run the same units, and travel in vans and aeroplanes....

It's weird watching someone talk about a spring reverb like it's fragile and overly succeptable to electrical noise, after watching LMNC usually beating his spring tanks like they owe him money. Also, that tank you have for display is surrounded by heavy gauge steel sheet. If you have electrical noise issues, then you should probably be focusing on that problem, instead of letting it guide the rest of your system choices.

can i asked you why are you wearing gloves?

Really misleading video and real spring videos are awesome. Half the fun is manipulating the spring while playing through it and banging/slamming the case.

the springs dont pick up noise, the transducers do. also your music is too loud vs the voice

Hook a stringed instrument to it... can't tell crap like this

Thumbs up for the module itself and for the demonstration... Thumbs down for the rubber gloves and anti-static wristlet. For god's sake!

Cool vid but what’s the point? I’d rather spend my time creating music and practicing as opposed to building something I could easily purchase.

I learned nothing
