Great unit

I'm really glad I got these since I was a bit on the fence about the AbbeyRoad sound initially. We all know and love Neve and API or tube, but the AB sound/hardware was always a bit more difficult/expensive to get a hold of. Very 'finished record' sound, thick, smooth and upfront. I can only compare these to the plugin emulation from A**stica.... and...as expected, these are better than the plugin hands down. (deeper soundstage, fuller, smoother)
Excellent kit, documentation and look/feel. Pretty straightforward build. So happy with the whole experience I already ordered the Tube pre's. Cheers to JP!

Great

I was especially looking forward to the MP573. I’d already built an EQ-573-II and an LA502 before. The order was just right. The “routine” for the build really paid off. I have to admit, when I was soldering the gain switch, the density of the pins did make me a little nervous.
But thanks to the detailed instructions, everything worked out perfectly on the first try.

The reward is a great preamp that sounds really good. When I combine it with the other modules, I have a channel strip that’s just awesome.

I’d like to thank SSK. The kit is really great.

Great EQ - love it

After the LA502, the EQ573-II was the second module I built. The EQ is significantly more complex than the compressor. The most important thing — and here I agree with the previous speakers — is to take your time. You have to work very carefully, especially when mounting the many capacitors. If you work neatly, they fit well on the board.

And now for the most important part: the sound. It’s a treat to listen with just your ears. I really enjoy working without the distraction of colorful EQ curves.
The highs are addictive. I have to keep reining myself in. With vocals and acoustic guitar, you reach your goal very quickly and put a smile on the musicians’ faces during recording.

Unbedingt empfehlenswert

Ich nutze den MC624 in der fertig montierten Variante seit zwei Jahren beruflich an einem analogen Audio-Messplatz und bin mehr als zufrieden: sehr gute Verabeitung, leichte Bedienbarkeit, beste Messwerte und hervorragende Audio-Qualität und falls mal was kaputt geht: (abgesehen vom geschlossenen Stromversorgungs-Modul) - keine SMD-Technik!

Son trés chaud

J'ai ce préamp depuis maintenant 1 an et je dois dire qu'il est vraiment trés bon.
Il sonne magnifiquement, genere de magnifiques harmonique qui rechauffe tout ce qui passe dedant. Grace au niveau d'entré on a la possibiliter de le faire saturer plus oui moins et tout ça de facon trés musicale. Il a un super niveau de sortie. Je l'utilise sur des voix, des guitares acoustiques, sur des Overhead aussi bref tout ce qui rentre a l'interieur en ressort avec un vrai grain magnifique. Encore un super Préamp de chez Soundskulptor !

Un pure bonheur

Encore un coup de maitre avec cet EQ.

Il sonne vraiment bien et est plus complet que l'original.

Merci pour votre travail.

Super

Excellent compresseur ultra complet, peut être utilisé sur tout un tas de sources sonores, le bouton "dist" rajoute une vraie présence sur les voix,
La compression est très naturelle, on peut compresser 15db et ça sonne toujours bien.
Super également sur des drums pour leur donner un effet disto en rentrant fort dedans.

Perfect Introduction to DIY 500 Series Gear

For starters, I don't know that I'd recommend this as your *very first* soldering project. It is not a difficult build at all, but personally I'm glad I tried my hand at something even simpler (like a Fuzz Face-style pedal) first to "iron" out the kinks in my soldering technique. My first pedal build did have some issues, which were not hard to trace out and fix in that tiny circuit.. This circuit is nothing crazy but it is definitely more complex than a Fuzz Face! Just food for thought.

That said, I don't have a ton of experience beyond a handful of pedal builds and a whole lot of cable assembly, and it went very smoothly, testing out as expected on first power up. All in all, the build was finished and tested about a day and a half after the parts arrived, probably ~5-6 hours total, moving at a leisurely pace. Also it arrived lightning fast, being on a different continent (US) I didn't assume I'd have the parts within a week of ordering, let alone have the whole thing built, but sure enough it arrived only five days after ordering, mad props to Sound Skulptor for that.

Lastly and most importantly, the quality - this thing sounds phenomenal. Optos are my favorite style of compressor and I'll admit I was highly skeptical $300 would build me anything all that special, but I was wrong. Almost bummed I have no need for all those LA-2A plugins I've got now... This is all I'll need, at least until I find a good tube-based opto build to add to the collection! Even then, I have no doubt this will be getting used heavily for a very, very long time. Especially love it on a bass track, no surprise there as that's always been one of my favorite uses for an opto. I also have no doubt that I will be ordering many more kits from Sound Skulptor, if their other units live up to this experience then I can't imagine there being a better value on the market.

I love it

The LA502 is my first, but definitely not my last Sound Skulptor module. The kit is very well sorted and the instructions are excellent. There are numerous Youtube videos in which Sound Skulptor modules are assembled. If you prepare yourself, you will also learn some tricks on how to solder better.
I took my time with the assembly and worked carefully. As a result, everything worked right away.
And the sound of the compressor? Fantastic! I love it on vocal tracks.
Many thanks to the Sound Skulptor team

EQ250 done....and happy

Have built this kit,all went very well and easy,absolutely no issues.Parts were complete to the very last solder nail.I loved the idea to have a 250-style eq in stereo,mainly on the bus (I already have a few mono versions which are frequently used with an MS-matrix).Build quality is excellent,the pots are directly mounted to the frontpanel so nothing wiggles or feels floppy.The knobs are collet knobs,this couldn´t be done better.I ran some music through it for testing,it sounds gorgeous!
Again: Chapeau bas to Jean-Pierre and his team!
As said before:I´m happy!
