Reverb Goes to Eleven on this Vintage Amp

The Ondes Martenot was one of the very first electronic instruments that was embraced by composers of orchestral music. Looking to expand its sonic range, Maurice Martenot developed a series of amps around the instrument, from a normal speaker, to tuned strings, a resonating gong to this strange box here. Manufactured by Rehdéko, a long defunct French high-end company, it uses seven brass strings attached to the speaker cone. This creates a rather lush and surprisingly dense reverb, with no feel of the "boingyness" of usual spring reverbs. As I am a fan of unusual speakers, see "Gong Amp" I made with AudioThing (www.audiothing.net/effects/go..., I could not resist its allure.

Let AudioThing and me know if this would be worth a plugin like Gong Amp: www.audiothing.net/effects/gong-amp/ If yes, what features would you think interesting?

[@SzopenOffiziell]

First thing I thought when I saw this...totally yes ❤

[@dedicatedspuddler7641]

I think this would make a terific new product from Audiothing!

[@eveningdreamermusic]

an audiothing plugin would be amazing! maybe one of the features could be to lengthen/shorten the springs? or some damping stuff like the gong amp & some feedback options?

[@luxinterior5]

Tension control for each spring along with some kind of "tuning" of the springs harmonics (if It makes any sense lol)

[@zakkacreman]

Plugin would be cool; or even just an IR

Whenever talking through a reverb for the first time it's traditional to pretend you have been trapped in a well

[@seancurtispatrick]

Thanks for letting me hear my Ondomo through the 'ole Rehdéko! It was very rewarding to hear it play back via the speaker designed for the instrument! :)

[@Hainbach]

Thanks for taking part in the video!

[@alainreimbolt581]

I know the father and son creators of these speakers (father Weber Rehde has unfortunately passed away) and you have the small model of these reverberant speakers.. they were sold in pairs to accompany the hifi speakers in their range and give a powerful effect. concert hall. they were limited in power and reverberation length by an electronic box

[@Hainbach]

Interesting! So they had use beyond the Martenot. Thank you for sharing, and maybe you could send this video to the son?

[@niteshades_promise]

larger stereo speakers like this would be awesome. 🍻

[@HANGINGOUTWITHAUDIOPHILES]

Yes! What a wild time it was. The gong, the harp, the springs. Really they were magical transformations to the simple tone world of the ondes. The fact you can now run a drum machine through this is superb. There’s so much to discover bringing these worlds together.

[@GL-iy7mj]

[@arachnenet2244]

Imagine DSBM vocals through that thing! I'd absolutely love to hear that!

[@Hainbach]

I brought up the only other one I had, the hifi amp I got when I was 14. That of course did not work, and the footage was lost to out of memory camera anyway

[@i.shadrin]

+10 for the plugin

[@LightProgRock]

I've built one, because I play Ondes Martenot ! If you ask people that play Ondes, they have all the answers, including the type of springs to use

[@LYFoulidis]

Doh, of course I’d like the plugin. Instead of the pillow I’d propose to squeeze the tips of some patch cables between the springs at different points to get weird resonances - I love that trick with spring reverbs!

[@BuiltbyF]

The 5 seconds or so of you taking the cover off is enough resample material for a whole track. That's when you know it's good.

[@JoshSemans]

Incredible! So glad to see that one of these beautiful speakers is in your capable hands!

[@Hainbach]

Yeah lucky find! I have to experiment with micing it and using different amplifiers

[@JoshSemans]

Re: the springs Grab yourself a set of suitable springs, and an appropriate mathematician, and then pair those springs to a matching speaker… …not forgetting the frame 😆

Your prononciation for "Ondes Martenot" was good, Hainbach. I' m French and I understand it, with your accent obvioulsy, but the "on" in "ondes", the tough part, is good.

[@brumd]

Wonderful speaker! An Audiothing plugin sounds very interesting. 7:07 These longer notes instantly remind me of The Residents (which of course is a good thing). Don't know if that is due to the Crumar Spirit or to the speaker or the combination, but it makes me happy. :)

[@jeffevansmusic]

I bet if you put a coincident pair of mics right in close to the speaker you could capture the reverb in stereo too. A plugin version should include a stereo option.

I experimented with making speaker and piezo buzzer driven spring and plate resonators when I was a kid, they’re great in a feedback loop. I once scrounged a big spring similar to the ones used in this device, and the bigger springs definitely sound more interesting.

[@centerstarstudios819]

The drums sounded amazing!! Please make an Audiothing plugin from this amp!

[@valentinbecmann7908]

Hello ​@Hainbach, First of all, thanks for your content and its quality. How did you make the connection with Ondes Martenot ? The Martenot "diffuseurs" (sound difusors / amp) were from a different design from what I can tell. I own one of those spring speakers and I've read in French after some research that the Redheko speaker model you reviewed was originally specifically designed to accommodate small studio room design and, as @alainreimbolt581 wrote in his comment, in addition to a little controlling device that can adjust the reverberating time of the speaker, virtually extend room proportions, natural reverberation and stereo imaging. All the best, Val.

[@Hainbach]

Thanks! It was sold on Reverb France as an Onde Martenot amp

[@user-wo3mb6qc1i]

[@hitsonacousticguitar]

The amp sounds great here and the the reverb is very "musically".

[@_robespierre]

omg this thing must be pluginized. the sound is just too bizarre and good

[@soaringtortoise]

Plug-ins are great. I hope you do that. Sadly (not really), I don't use a DAW. I would be much more interested to know what the secret of the springs is and why it can't be currently reproduced for the analog world.

[@wul01]

All my hearing should come through that speaker.

[@newtronix]

Where did you get that t shirt from? I love it!

[@mr_floydst]

Interesting! So having two of these would result in a true stereo reverb...

[@ibanezleftyclub]

Run a thermin though it, I bet it would sound otherworldly, especially if you added some delay and chorus. You also need a second one for stereo lol

[@NicStage]

It's always challenging to create these types of things DIY style. I've tried and been less successful than I'd expected / hoped in the past, too. You really notice how small details about the composition of the resonating pieces really makes a big difference.

[@Hainbach]

Yeah the devil is in the details so often. You can get near but to finish something like this and make it reliable to last a few decades is a long process.

[@PorchBass]

There is a guitar pedal called prismatic walls that uses Karpluss Strong dsp to get a similiar effect

[@SidRockett]

Well now we just need to sit and wait until Sam figures it out. Lovely thing this speaker.
