Author [PROJECT] Music Thing Spring Reverb
Tombola

The Music Thing Spring Reverb is a flexible, easy-to-build voltage controlled 6HP DIY mono spring reverb module.
- Works with a variety of spring reverb tanks (including the A199 mini tank), or with the Accutronics BTDR-2 reverb ‘brick’ designed by Brian Neunaber
- Two cheap PCB panel designs - one with front panel sockets for the reverb tank
- Vactrol crossfade between dry and wet
- Tilt EQ on the reverb send to tune the voice of the reverb
- X-Fade input so the module can also be used as a standalone vactrol crossfader (crossfade demo video)
- Attenuverter on the crossfade CV input

All the details are on the Music Thing Spring Reverb Project Page including:
- Big instruction & build manual that will answer all your questions (PDF)
- Schematic (PDF)
- Eagle and Gerber files, front panel specifications, a Mouser BOM etc

THONK will be offering PCBs and panels

Excellent applause

nice redesign on your site too!

I actually have a few reverb bricks sitting in my parts bin
might just have to try this out.

Excellent work, Tom!

I only discovered this project earlier in the week and it's the perfect final piece in my modular puzzle.



A few questions:

Is the small blue reverb tank shown in the build document available yet?
Could you share details please?

The panel documents show the co-ordinates and diameters of all the panel-mounted components.
Could you tell me the co-ordinates of the PCB mounting holes relative to these please?
I'd like to mount the PCB sandwich parallel to the panel but using stand-offs.

Do you know if Thonk will be keeping stock of the Spring PCBs, like your Turing Machine?

Thanks for making this project available!

It's on the Accutronics site: http://www.accutronicsreverb.com/main/?skin=sub01_08.html
I think they'll sell direct and they're looking for retailers.

Sorry, I don't have that information - I'd have to go back to the Eagle files and do a bit of maths.

I can't speak for Steven, but I think that's what he's planning.

Here's a video showing the crossfade mode; mixing between Fold and Square outputs from a DPO

all the demos sound absolutely fantastic. very keen for this, the crossfader functionality is a great bonus too. nice work applause
regenbot
perfect applause
Spip
Really nice thumbs up

Is it possible to buy the PCBs ? Will you make them or someone else, maybe ?
Spip
After a quick look at the BOM, I don't see the vactrols Silonex 32SR3 and VTL5C3 in the list ?
Am I missing something ?

I already have almost all the other parts though ! w00t

Sorry, Mouser don't sell vactrols at all (or any LDRs). You can get VTL5C3s from Thonk or the Silonex from Farnell.

If you have the choice and you're going to the the x-fade mode at all, I'd choose the VTL5C3 - it's smoother and slower response.

I've made PCB and parts orders for kits so its all well underway.

Will have 4 panel options.

Aluminium panel - Tank connection on front
Aluminium panel - Tank connection on back
Low cost PCB panel - Tank connection on front
Low cost PCB panel - Tank connection on back
rosch
this is cool! so i can also use the bricks!
just perfect to build more than one hihi
Isaiah
Monobass
Rockin' Banana!
Will you also stock just the PCBs?
Monobass
Yup thumbs up
Spip
@Tombola : Thanks. It seems that Thonk will also sell the PCBs. That's handy.

@Monobass : I don't see them on your site. Any idea of the prices for just the PCBs (and some vactrols).
Monobass
It'll be 3-4 weeks until they're in stock. Will have prices a day or so before they are in stock.
Spip
Ok. Thanks !

Sounds fantastic!

Thanks for all the information thumbs up
I'm looking forward to using this!

If there's any chance somebody could check the files I wouldbe most grateful.
Thanks!

Cool! I'll be in for it for sure. Have an A-199 but want the CV features in this.
Monobass
It leaves the 199 in the dust of its wake smile

It makes the 199 tank sound hi-fi too hihi
logicgate
are you storing the tanks too, mate? I mean, they will be in the kit?

Haha in what sense do you mean that? (Re: making the 199 tank sound hifi)

I think he means that you can plug the reverb tank from a A199 into the Music Thing module, and you'll get a cleaner, sharper, more bass, more highs sound.

I haven't been able to try it myself, but the intention of this module is to provide a warm, deep, clear reverb which can then be messed up in a whole variety of ways.
