Diamond - Compressor [new gut shots added] [traced]
Information

I bought the parts a few days ago. Still waiting for them.
When I have some progress I will surely let you know but I was just asking if maybe someone else tried this layout..

Just verified the vero layout I posted on page 4. I replaced the odd values with cheap and common replacements, used 2N3904 throughout, and rolled my own opto-coupler with an LDR, a LED and some shrink tube. Worked nicely!

so it's nice?
how is the sustain? can you do clean sustained solos?

I can hardly play so probably not. But seriously, there's demos of this thing on youtube. I think it sounds nice, but I encourage you to build one and try for yourself.

the pedal sounds good to me in PGS demos, the only thing i'm not sure not is sustain, but i guess i have to try it to be sure

if you want sustain then try out a tc electronic sustain+parametric EQ, I have a reissue, the compression it's pretty transparent and it can sustain for years!

thanks Gila! i'll see. really i'm looking for something diy, but there's not a winning candidate for now,so let's give space to anyone

once again does anyone know what it's like on a bass or at least try a bass on theres to let me know or is it only guitarist on this forum? I'd love to know so i don't waste my time putting it together for bass. I have no problems in putting one together its just so many times i think oh this one sounds great put it together to then find out it sounds terrible on a bass guitar. As it was soley designed to be effective on a guitar. I do know that you double the caps in the signal path for bass but that doesn't fix everything. If anyone knows the changes on the diamond bass compressor please let me know. cheers

I was having a look at the TC Sustain the other day, and was considering designing a PCB and vero layout for it, without the equaliser section (which always seemed superfluous to me). I used to own one of these, and the sustain was amongst the best. It has the advantage of not requiring opto-couplers, and doesn't use the 3080. It also has "low level expansion" - better known as a noise gate - which I found to be very useful.pietro_moog wrote:thanks Gila! i'll see. really i'm looking for something diy, but there's not a winning candidate for now,so let's give space to anyone

For bass search for THAT4301 compressor, build it ( you can try it with nonlinear capacitor for timing capacitor which will help with low frequency ripple and improve overall distortion of circuit. All info can be found on THAT CORP web site) , it will not disappoint you, its a studio quality in a stompbox. In other hand opto compressors sound good too. For bass compressor very important is side chain circuitry than audio path ( I might be wrong but its my opinion).seedseed wrote:once again does anyone know what it's like on a bass or at least try a bass on theres to let me know or is it only guitarist on this forum?

Thanks for your response lietuvis, I have found that opto compressor are great for bass the la-4 would be great for the job. The thing is some of the pedals getting around the schematics aren't far of in size of some of the so called studio compressor's The whole thing is is in diy how good you are in fitting lots of circuitry knobs and switches into a smaller box. Obviously if your power supply is not in the box most so called studio compressor's can easily fit into a stompbox. You just don't get things like vu meters and stuff like that. Unless your highly inventive and work out a way of maybe doing a led vu meter or otherwise your a genius and manage to stuff everything into a small box. If you look in the cases of most studio compressor's theres a lot of room to breath. Thats why you see so many get released as pedals. Especially with the advent of surface mount. Some of the more how would you say more featured lets put it seem to be going more and more surface mount. the hardest thing to identify on surface mount is the capacitors there generally not marked and hard to identify on the board ( although if you know a good technique let me know) and on the down side you start squinting like mr magoo by the time you have finished trying to trace one. the compressor that i heard a lot of bass players like is the EBS multi comp that sucker is surface mount i would love to get my hands on a schematic for that one it looks really good but yeah if one is patient enough you never know.

hi guys!
i'm thinking about building this comp.
so, while i wait to build a new pedalboard and a proper power supply, i need to know whether a 18v (icl7660s) pump could power all those transistors and opamps
in a good way.
any experience?

Please do Mictester ! I have been wanting to build this one for years but haven't got the time unfortunately.I was having a look at the TC Sustain the other day, and was considering designing a PCB and vero layout for it,
Would be great if you could post it here !

Hi guys,
a quick question about the 3PDT wiring;
1 = circuit out 4= Jack In 7= 9V
2= Jack out 5= Circuit In 8= R40(from schematic)
3= Jack In 6= Grd 9= Grd
Can anyone tell me if it is correct?
Thanks

Transistors are 2n5088 (Q2,Q4,Q8,Q9), 2n4401 (Q5,Q6,Q7), MPSA18 (Q1,Q3).Ripdivot wrote:Has anyone figured out what the transistors are yet?
Pretty much. I tend to think of 2n5088 as the most generic transistor in existence, 2n4401 as half-gain 2n5088, and MPSA18 as a double-gain 2n5088.WhiteKeyHole wrote:Doesn't really matter. All the common stuff will work.

can i ask sir..
about the ic op275.. can it replaced with other series?
