Whats different from the basic DIY version?

I think the parts can be sourced for about 100 euro. The rest of the cost will depend on how fancy you want the unit to look.

You can spend a lot of money on high-quality parts too I guess, but to me there isnt really a world of difference with this one.

Im doing electronis music here. Samples and hardwaresynths here.

Hi Christian,

Well one major thing about a stereo 1176 is that is will track FAIRLY well, but the stereo tracking between them won't be as accurate as the GSSL for some of the above mentioned reason, plus sonicaly it has a very different sound.

I have an ADR Compex which I used for stereo FET (and 1776 is FET compressor, not VCA based, incase you didn't know) compression over a drum/mix buss though I find 9 times out of 10 at least for Drum Buss I reach for the GSSL, it just pulls the kit together in a very unique way as only the 4000 series buss comp does, spongy, gluey and pulls in the air around the kit.... sorry I can't be more descriptive

I built a GSSL for a friend here who has studio and has an electronica project called 'LARK', the GSSL was used extensively on their records, so much so he asked me to build him another, LOL! Check them out here: MySpace.com - LARK - Cape Town - Electro - www.myspace.com/larksa

HELLLLL! I wished I lived in Europe! I guess being in Africa and importing everything for 3-4 times the price you pay and then still being hit with VAT and import taxes bites... but it also has its advantages.

I beg to disagree on the parts. I built 2 different units, one with the EPCOS/Panasonics and another with WIMA's and just changing those made a VERY discernible difference in sonic character, the EPCOS being darker, and warmer, the WIMA's being a bit more open and 'hi-fi'. And also using quality long life, 105 degree, low ESR lytics now means I may get more use out of it years to come rather than some cheap, leaky no-name brand lytic I used to save a few cents.

Part of the point of DIY is that you CAN choose to use better parts than what many so called 'boutique' companies are selling a fairly heafty price but cutting corners using cheap ass parts... that was at least WHY/HOW I got started building my own gear a few years ago.

Also I think why spend money on making a piece of great sounding gear but make it look cheap with a bad looking case? My case cost 80 Euros to make and think it now not only sounds great but kind of looks it to.

Cheers

Hey Matt

Thanks for your thoughts!


It will be a GSSL then! I don't have the time to build one but I know someone who could.


I don't wanna hijack this thread but what do you think about the ME 1968 (tube action..anyone..?) for the Master Buss?

Maybe I can get a custom stereo pultec for that 1968 money. But it is transformerless, not the original , cleaner ,Class A,discrete but same characteristics. Would you rather go the pultec route instead of tubes?

I know Thermionic Phoenix would surely be the dude here. But let's face it , this unit is f****n expensive!





Greets to Africa!

Hi Brad,

Which cinemag did you use? 1:1, yes? Have you compared it to a transformerless version?

Hey Matta!

Im sure theres some sort of low-point you can step below qualitywise, but the difference you describe doesnt seem like one is better than the other. One is just different?

Just want to make absolutely clear. I meant 100ish euro for the electronic parts only. You can do the unit in an ugly-ass box with no meter, or you can do it with a fancy meter, a good case, good quality knobs and a custom made frontpanel. Hence the total will depend on how fancy you want the unit to look. Were still not talking about huge sums though.

Making it really cheap might seem a little crazy to you, but some people are worried they might not even get the unit working - to them it makes more sense to do it on the cheap I think, and they will still get a great sounding unit in my opinion. Its easier to try and evaluate different ICs, Caps, pots etc after you learn what they even are.

This is a shopping list for a danish shop. (el-supply.dk) which takes international orders. The caps are WIMA.

I love the gssl, but it started really to shine after Michael of tegeler-audio-manufaktur did the side-chain filter mod.
I have the sidechain doing all this stops:
1 - Flat
2 - 60Hz
3 - 80Hz
4 - 120Hz
5 - 180Hz
6 - Thrust light
7 - Thrust full
8 - external Sidechain


6 and 7 are inspired from API 2500 and this is Very useful.

here is the info about it:

Hey Gustav!

Thanks for the tips man. I'm going to see if I can't use that company for the Night EQ I plan to build from Peter C's board. Part of the problem buying parts here as well is a lot of them have an MOQ, which is great for some stuff, like buying 50 x 0.1uF WIMA's is great since I'll sue a lot of them over various projects but when you get to the 1uF caps they get VERY expensive and taking 50 increases costs a whole bunch :-(

We can order from Farnell here, which I've done through a company called Mantech, but to work out what I pay I have to take the UK GBP value and multiply it by 26!!!!

I've had good luck with Small Bear though, Steve is great! I got my VCA's from him and they were VERY reasonable.

So true, both sound great, just different!

Look great!! I like the contrast of the panel and the knobs, almost 70'ish.

But it sure makes it look a lot cooler and we all know it sounds better if it looks cool, LOL!!!

I used the CMOQ-2L. I wanted color, but not as much as the 2S version gives you. So I settled on the low nickel version. I did compare to a friends stock GSSL...but there were so many other differences between the builds that it's hard to tell. Compared to the Waves SSL Comp, mine sounds more hi-fi with greater depth and more refinement. It's not as aggressive and thwacky so it lends itself to use on a greater range of stuff.

I have finished my first GSSL this friday and I am currently mixing the first project with it and it absolutely ROCKS. heh an instant smile on my face. I have another one already assembled just need to test it - the second one is build with the siedechain mod.

the project I am currently mixing is a HC/metal band - the thing just works fantastic. It's inserted in my neve 8816's master section and the two units together are awesome (the neve width control is cool too )
all I need now is some really cool AD/DA - I am saving for the HEDD and that would finalize my master bus chain

Gyraf Ssl comp!!!Yes indeed!!

Best thing i ever build (around 365Us and 35 hours, ca 10 hours build and the rest hunting components.. was lucky to fing proper circuit boards and case which made it a lot easier & faster.) after 12+ years of fulltime work in electronics i still managed to get some things wrong but now it all works great. (Thanx forever Jakob, Swedish chef & east europe metal guru)

Now back to that Pultec clone that´s been in the works since early 2000... Every D.IY can name their list of projects ..."In the works"....In Sweden the old stone workers called old pillars, statues and other stone works that was "killed" by one wrong hammer hit "Wolves" and the builder sometimes killed themselves as the payment for a years work was only for flawless deliverys. They still stand around the coasts around here.

Well i´ve briebed myself with a big night on the town once this beast is of the ground working

Now i have a new rule (Ok í´ll break it as soon as i hear the word with the big N) I will NOT start another D.I.Y until the last is finished and in the racks earning it´s keep.


G.slut rules!

Hi Ipagel

I'm just finishing off a couple of gssl's and have been looking at options for putting the text on the front panels. I was initially going to have Schaeffer make me the panels but have now decided that I'd like to do as much of this as I can on my own. I'm thinking about having the panels screenprinted and that leads me to my question/s. Are your panels screened or is that a vinyl decal of some kind? Where did you get it done and how much did it cost you? Looks beautiful

I'll even throw you a bone. Here is a step-by-step process for Lazertran I put together when I built my first GSSL a few years ago: Prodigy Professional :: View topic - My first attempt at Lazertran

I also wanted to share that I'm receiving a copious amount of e-mails from fellow Slutz asking me what I would charge to build them their own GSSL after seeing the pics of my latest unit. I've responded to many of you personally with the same response but I'll share here to save me responding to personal mails... I don't build GSSL's FOR SALE.

The GSSL was designed/conceived by Jakob Erland of Gyraf Audio fame as a FREE 'Not for Profit' DIY project geared at guys wanting to try their hand at electronics and DIY. I want to honour that and thus don't offer 'cloning' services through Ashton Audio. While my Gallery shows clones of the 1176, LA-2A and the GSSL these are my own private units in my personal studio... I'd be happy to offer my racking services, custom wiring and commercial projects, I just don't sell 'clones' that were presented in good faith for FREE to the global community.

I did a small run of 5 units for friends and colleagues (with Jakob's blessing), 2 for me, 3 for them to offset my costs and I won't attempt this again as really the hours spent on them for trades as opposed to cash really isn't worth it.

Also wanted to share while the GSSL is based around the SSL G4000 Buss Compressor it isn't a 'clone' as many aspects have changed from the original design, while retaining the essence/character to the (in)famous VCA compressor.

I've also shared with some of you that I think this is GREAT project to get started with as an introduction to electronics. It isn't a kit form project, you need to purchase the parts, circuit boards, and enclosure, power transformer etc.

There is a HECK of a lot of documentation over at the Prodigy-Pro Forum. There are also a multitude of ways it can be built with various VCA's etc. I think the easiest is using the pre trimmed DBX VCA replaces available from THAT Corp... I'm working on a parts overlay for this build that I will make available to the Forum which will help a lot of newbies along.

As Mattssons shared:

Quote:
Best thing i ever build (around 365Us and 35 hours, ca 10 hours build and the rest hunting components.. was lucky to find proper circuit boards and case which made it a lot easier & faster.
The longest/hardest part in starting out with this project is sourcing all the right components. Labs (Gustav) posted a parts list or BOM from a European manufacturer that ships internationally and I know there are other partslist for Mouser and Digikey other helpful DIY guys have put together for this project.

Many have shard with me that they know nothing about electronics or can't tell x from y, well neither could I before I threw myself into the deep end a few years ago... prior to attempting my first project I'd not so much as soldered a mic cable....

It isn't all easy, it might be if you build it paint by numbers style, but part of the fund is learning HOW electronics work and WHY, not just that they DO... there is a Newbie resource in over at the PP Forum and is a great place to start.

I hope that helps and hope to see some of you aspiring tech heads getting stuck into your own GSSL!

Cheers

Thanks for the information Matt. I actually have some Lazertran which I picked up after reading about it on the prodigy pro forum. I'll give it a go this weekend. As far as I'm aware, you can't print white with Lazertran. Anyone confirm that?

You guys should get over to the prodigy pro site and check out the gallery, where you'll be able to check out some of Matta's beautiful work

I've been trying to register there for a couple of months but haven't had a reply from the admin's yet. Hopefully soon

I also wanted to share that I'm receiving a copious amount of e-mails from fellow Slutz asking me what I would charge to build them their own GSSL after seeing the pics of my latest unit. I've responded to many of you personally with the same response but I'll share here to save me responding to personal mails... I don't build GSSL's FOR SALE.

The GSSL was designed/conceived by Jakob Erland of Gyraf Audio fame as a FREE 'Not for Profit' DIY project geared at guys wanting to try their hand at electronics and DIY. I want to honour that and thus don't offer 'cloning' services through Ashton Audio. While my Gallery shows clones of the 1176, LA-2A and the GSSL these are my own private units in my personal studio... I'd be happy to offer my racking services, custom wiring and commercial projects, I just don't sell 'clones' that were presented in good faith for FREE to the global community.

I did a small run of 5 units for friends and colleagues (with Jakob's blessing), 2 for me, 3 for them to offset my costs and I won't attempt this again as really the hours spent on them for trades as opposed to cash really isn't worth it.

Also wanted to share while the GSSL is based around the SSL G4000 Buss Compressor it isn't a 'clone' as many aspects have changed from the original design, while retaining the essence/character to the (in)famous VCA compressor.

I've also shared with some of you that I think this is GREAT project to get started with as an introduction to electronics. It isn't a kit form project, you need to purchase the parts, circuit boards, and enclosure, power transformer etc.

There is a HECK of a lot of documentation over at the Prodigy-Pro Forum. There are also a multitude of ways it can be built with various VCA's etc. I think the easiest is using the pre trimmed DBX VCA replaces available from THAT Corp... I'm working on a parts overlay for this build that I will make available to the Forum which will help a lot of newbies along.

As Mattssons shared:



The longest/hardest part in starting out with this project is sourcing all the right components. Labs (Gustav) posted a parts list or BOM from a European manufacturer that ships internationally and I know there are other partslist for Mouser and Digikey other helpful DIY guys have put together for this project.

Hi Matt,

I was one of the people emailing you. I really want to learn about electronics and especially building DIY compressors etc.
Like I said I know jack but am keen to learn.. Do you have a link to the newbie section?
Is it really possible I can do this? If so I will source the parts asap.

Cheers,
Jonny

(Just to clear up on the previous stereo-width confusion: The Clone uses sidechain summing, but the original does this as well! The two units are just summed at different points in the sidechain, so that the Clone compresses relative to the sum of the input signals instead of compressing relative to the sum of two rectified-and-timed sidechain DC components like it's done in the original...

For all stereo-with-purposes they should be equal.)

I'm thinking about having the panels screenprinted and that leads me to my question/s. Are your panels screened or is that a vinyl decal of some kind? Where did you get it done and how much did it cost you? Looks beautiful

Hi thanks for the nice comments.
i used lazertran to do the labeling.

here is my flickr album:
Flickr: Photos from Gaff's

first i drilled them then painted with some Audi white paint made up from the local car paint shop. then did the lazertran and then lacquer (get a mask to do the lacquer as it make you dizzy .

paint charts:
AutoColorLibrary Color Chip Selector

used this great piece of software/web page along with illustrator for the dials:
Scale-o-matic

for the meters i got from CPC and drilled into the back of the meters (as this is the most expensive bit of the build was a bit nervous) and just run 2 led from the power led placement on the control board.

so happy with how they look and sound.
the only problem is now i am hooked and am in the process of building peterc's green pree and nite eq, Peter p's 525 clone and some neve preamp clones.




case £35
meter £30
paint and laquer £20 (but still got plenty left)
lazertran £8
