Well, today I received the dynacomp pedal I got from Ebay.
It appears to be a mint condition Rev. D pedal, although the previous owner did put some velcro on the bottom, which is not a big deal.

Plugged in, it's a little disappointing, even at minimum settings it squashes a fair bit and the attack time is way too slow for my tastes.
The result is a loud first note, and then it squashes the rest.

So far I only tried it with bass, not guitar. And I put it in front of the amp and in the fx loop which doesn't seem to differ much (I prefer a straight signal to the amp, and then some compression before the poweramp, basically I try to emulate a tube amps behaviour with it).

So if anyone knows some cool mods to adjust the attack time, and to lighten the compression a bit you're welcome.
In the meantime, I'll keep using my beloved old CS-3

This something that gets me thinking as well..i must be one of the few people here as well that likes the CS-3,and then when i see people slating it i start thinking if there is something better out there like the MXR or the Analogman Bi-Compressor...?..but then i read a post like this...... i think i will stick with my CS-3 as well........

Dirk,

It might be worth it to get a vintage Dyna and not a re-issue. The older ones are better....

You guys are definitely among the FEW that like CS-3. I most certainly am not one of them, as I find the noise floor to be too high on that thing. I am a huge advocate of the CS-2 however. I also own a CS-1, but that's a different "colour" entirely.

CS-2 wins overall in my book

I really dislike the 'floor' noise and the swelling under the CS3 too. If you are country picking and you want that 'slick' even country picking sound it really shines here.

I had an old 1980 DOD 280 it was pretty sweet but the old mechanical effect engage/disengage switch left something to be desired; tone was sweet on a Fender guitar tho.

Hi Dirk

From my recollection & experiments, the Dynacomp is more for 6 string guitar, rather than for bass.

You might be able to increase the input/output caps to accommodate the lower frequencies of the Bass.

There are some mods on the pisotones site:

Original:

Tonepad has some info as well, & sometimes some mods:
http://www.tonepad.com/project.asp?id=9

I built the one on pisotones, & it's OK, not my fav. compressor, but it has a few more options that the original DynaCom.
He added a switch for soft-hard knee and a
Bright-normal switch as well.

If you're interested.
Here is the old May 2007 link, for when I was building this pedal (2 pages):

Hope this helps?

I like the MRX Dynacomp, and CS-2, they are quite similar sound wise.
But one compressor I like even more is the one in Visual Sounds Route 66, amazing, and it has some serious gain boost too.

Hi Goran & Guys

I was lead t believe, that the Route 66 was basically a Dynacomp Clone & A TubeSceamer clone combined into a single pedal.

But from your description, the compressor side is different.

Any chance someone can upload some internal pics of the Route 66?
or at least tell me the part number of the VCA in it.

Hi Dr. Bob,

Thanks for the links, I'll see what I can dig up from those.
I tried it with guitar, but I had the same result, too squashed even on minimal settings.
I haven't tried it with single coils, cause I only have a les paul with Seyour Duncan Alnico 2 pros.

Basically, I read good things about the pedal and my favourite ever bassplayer Billy Sheehan mentioned that he had one of those when he started playing, so I figured I wanted to try one out myself.

Thanks guys, I'll keep you posted.

Hi Dirk

The modified one I built, sounds pretty good in Bright mode, & on soft Knee setting.

But sound is so subjective, I'm not sure you would find it useful.
And I don't have access to a vintage MXR DynaComp, to compare it with.

the dyna comp is probably my favorite out of the box non-boutique compressor that is currently in production.

not amazing, but generally adequate and solid, especially since they carry a used price in the $30-40 range.

i'd definitely compare it more to a CS-2 than a CS-3.

Hi Zentropa
I know you get around a bit (equipment wise & musically) not the other way.
Is there any real credence to the Older Script Logo versions MOJO?
I do Know the older ones used an 8 pin metal can version of the 3080 VCA chip.
Or is it just the Older is better thing?

I don't even know who actually produced the original run of IC's,
perhaps there was something different about the Die.

The new ones use the plastic DIP, reason being, that the round metal can version, was dropped from production, & for handling ease.

If you have ever tried to fit the old metal can IC's, you would know what I mean.....
And trying to fit it to an IC socket, well not impossible, but difficult.

i've owned original versions of the micro chorus, 6 band eq, phase 90, distortion+, and dyna comp.

i've owned reissue versions of the phase 90, distortion+, and dyna comp.

honestly, half the reason i ditched the originals is because i got sick of wasting 9 volt batteries heh.

as a whole, i've found that MXR pedals are pretty mild in their differences from original to current. it's about on par with a MIT vs. MIJ but sometimes it seems the subtleties are purely caused by component aging and that they are manufactured with cheaper components nowadays in terms of jacks and pots.

the newer dyna comps are noisier and more "abrupt" in their effect than the originals. i don't consider an original to be $80 better than a reissue though.

on the phase 90's and distortion+ i only consider the originals mildly better.

keep in mind my base tone is always dictated by my guitar and amp and i never depend on an effect aside from possibly and overdrive or distortion. for someone who's big on compression it'll probably make more of a difference. when people consult me for rig advice i usually push the dyna comp as they are abundant and cheap used, but it's also mainly as a solo boost.

So far (this maybe usefull for Happyplucker as well, since he shared my problem) I've found that turning the internal trimpot makes a little difference.
Factory setting is in the middle, turn it all the way counterclockwise and the pedal gets a little milder, turn it clockwise and it becomes even squashier than it allready is.

I bet the pedal was designed with single coils in mind, cause compression level is dependend upon input signal strength.
So it doesn't seem to work with humbuckers and high output basses very well, although turning the trimpot counterclockwise helps a little but still not enough.
