MXR Dyna Comp

If you know what a Compressor does then this is obviously very easy to set up but getting settings you can use on clean and distortion channels within the same song is the tricky part!

Great High quality bit of kit!
Sustain and volume boost is great!

Don't know yet only been a week

Never used them

A genuinly pro piece of kit!
I use it as a constant effect its always turned on now matter what song, and no matter what channel of the amp I'm using.

I play through a Orange Rocker30 Amp head using a Fender Strat/Fender Tele/Ibanez Hollowbody/Esp F200/F400 and a PRS custom 22.

I've got it set up so it gives extra bass and a big volume boost on my Orange rocker 30 clean channel and it gives great sustain and what feels like added distortion but without making my sound messy!

One of the most simplist compressor pedal. I bought it in 1982 from United States. I found it very easy to shape your sound. The variable knobs are very effective. I still have its orignal maunal and it describes all the necessary informations. But I do not find its maunal as a key for operation but it rather tells what a compressor is all about. It do not have a variable attack control and it is fixed. I do not like its A/C adapter input jack as it is located at the side of pedal and secondly it is a male input pin-type one. I has a extremely low current draw only 1 mAmp. I probably replace its battery once in a year, amazing!

Simply the best sound quality especially for Clean tones but it still can give smooth sound while using overdrive. I found its overall sound very warm, creamy and punchy. It lacks the Attack control and I found it not so effective for hard rock distortions. Its really gives some of the most pleasant sounds by using Chorus and delay effects with clean sound settings on amp. Its sustain control is very senstive and its really makes noise if you cross the dial beyond 12 o'clock. I mostly use the sustain setting in between 12 to 01 O'clock which gives a tremendous control and dynamic quality to my guitar sound. This pedal does not have a bright sound but it is still very clear and transparent in all respects. It has a very strong effect and it always sound great.

I have been using it for the last 25 years and it is like a rock. In early days probably in 1983 once it stopped working. As I live in Pakistan so we did not have any service center here for it repair. So I took it to a private workshop and there it was found that its Chip got loose. So it was pressed into its grip and it started working again. Apart from this incident it never gave me any trouble whatsoever.

I play rock, blues, popular and country and it fulfill my music style requirements very well. I have been playing for the last 27 years and I have got lot of guitars, amps and Boss effect pedals and few from Ibanez,Zoom and Danelectro. If this stolen I would really become sad but probably I would not buy it again as I already got a Boss CS2 compressor. If I gets a second hand one cheaply then I will buy it again. I love about it is the extemely powerful warm, creamy, punchy and dynamic sound which gives a extra body to your sound. I choose it while reading a guitar magazine and got impressed with its properties. I wish it would have a variable attack and tone control.

It has only two knobs so it is quite easy to dial a sound that you like.
Very small pedal too...nice to carry around if you have to.

The only issue is that this pedal "colours" the tone of my amplifier. I didn??t spend fifteen hundred bucks on an amp to have a cheap pedal changing its sound so much...I have been playing for about five years with a Boss Cs3 modified by Pedaldoc and it doesn??t colour my sound at all...and the compression is much more effective.

Very sturdy. It won??t break on you.

Don??t know. I have had the pedal for about a month and it works like a charm.

Good pedal the only issue being that it colours your sound. It you don??t mind this get one and you won??t regret it.

Super easy to use. With only two knobs, its hard to mess this up. One knob sets the level of compression and the other sets the level of compressed signal that is put out. Easy!

This is where I'm getting off the "OMG-this-is-the-greatest!!!" bus. This pedal might be great for guitar, but it is terrible for a bass. I could not get a compression that did not either a) lose the lower frequencies, b) muddy up the whole tone, or c) distort when the output was turned beyond the 11 o'clock position. I wanted something that was transparent and light, but this pedal gave me that compression-as-an-effect sound. No good.

The pedal is built like a brick sh*t house. It is definitely a bargain there. It was actually one of the selling points over the Aphex Punch Factory, which sounds better, but is not as solidly built. Definitely a huge positive here.

N/A - Returned it to Guitar Center under their 30 satisfaction guarantee.

If I played guitar and could dial in the compression I am looking for without butchering my tone, I'd definitely keep this pedal. But, with the bass it is not so good.

It really doesn't get much easier than this as far as compressor pedals go. You get just two knobs, output and sensitivity. Output sets your overall volume, and sensitivity sets the amount of compression. The knobs are big enough that you can set them with your big toe if you are lazy. Getting a good sound is fairly simple, set the output where you want it and dial in the amount of squash that you want in the sound. Since there are only two choices, you're letting the pedal make some decisions for you so if it does something you don't like you're stuck with it.

If you are looking for a transparent compressor look elsewhere. The dynacomp definatly has its own sound. It adds some warmth to your sound by pulling some of the highs out. With clean tones it's very aparent and you can get the highs back with a quick eq adjustment on your amp, but it definatly colors your sound. If you set your sensitivity past 11 o'clock you'll start to get a thumb/fingerpick kind of sound. I usually keep mine around 11:30 as I find it to have a nice balance in it's effect, not too heavy. With an overdriven or distorted sound its effect is more subtle but very pleasing to the ear (mine anyway). It can really help smooth out some harshness in your tone and even everything out. I like it in combination with my Maxon OD-9, they work very well together. This pedal did introduce a bit of noise into my signal. It's a compressor so of course it amplifies what is already there, but it definatly add some of its own as well. I've also found it to work best off of the battery, no idea why.

It's pretty well used, solid and I'm not worried about it.

I really like this pedal. I play a yamaha strat clone that I've had for 10 years with some Lindy Fralin blues specials in the top and middle positions and a Duncan low-output humbucker in the bridge. The MXR runs into a OD-9 that feeds my Classic 50 head. This pedal matches my tone really well. I play just normal rock/blues/anything and it matches my playing style. I lean more towards blues guitar and this pedal fits in nicely. I love it for its simplicity but its also its downfall; if you don't like something you're screwed because you probably can't change it. If your looking for more of a transparent compressor you would probably be better off with the boss cs3 and I would be tempted to try that one next if something happened to the mxr.

Two knobs--"Output" and "Sensitivity." If you can't handle this level of complexity you really shouldn't be walking around without a helmet.

The "best" sound quality is achieved thusly. The first thing is to put the compresor first in your effects chain. Second, with your amp volume set where you want it, set the "Output" knob so there is very little--if any--difference in your overall volume when the compressor is on or off.

Now, tweak the "Sensitivity" knob (I wish I had a dime for every time I've written that) until you start to hear the sound getting "clicky" and then back it off about 1/16 of a turn or so.

There you have it. Transparency. An equalized signal suitable for finger picking, rhythm playing, etc.

It's not "indestructible," but it's more durable than it has to be.

Back in the MXR days, you could send your unit in for repair/checkup/refurbishment at any time for any reason for little or no $$ Now that the brand is owned by Jim Dunlop I couldn't tell you whether it's worth a crap or not. In fact I couldn't even tell you whether Jim Dunlop as a company actually manufacturers anything these days or if it's a marketing company that sells Chinese-made stuff.

I play guitar. Electric guitar. I have done so and received money for it for nigh on 25 years now. I've done everything from "Elvis Englebert Jones"-type orchestra stuff to 1970s and 1980s rock and metal to occasional punk stuff just to mess with the little bedwetting wanker wannabes at Guitar Center who can't fathom an old guy doing that*.

*BTW, nice Ramones shirt, kid. Did your Mommy buy it for you at Nordstrom? I got one just like it AT A SHOW. IN 1975! YOU LITTLE TWAT!

Just two knobs. Only problem I can see is that it is very difficult to make the battery fit inside the pedal. I would say this happens with all MXR pedals.

Great sound quality but still far from my Pedaldoc modified Boss Cs3. Creamy sustain though and good compression over all frequencies.

Looks very sturdy. I don??t thing you can break this think easily

-----------

Good compressor apart from the battery problem. Not as good however as my modified Cs3 which really sings. Buy it if you are looking for an affordable entry-level compressor.

Otherwise visit the modders sites. They know well what they are doing (I can tell you).

Only two controls so it is pretty easy to use. I however find it always difficult to put the battery into MXR pedals.

Good sound quality with little noise. I have heard that these pedals work better and sound better when the battery is low. I still have to try it. I have been using a Pedaldoc modified CS3 and I would say it sounds better than the Dynacomp (many of my mates agree) but I still have to mess around with this little thing.

Very sturdy. Will last forever if you are just a bit careful.

Never have contacted them.

Good pedal for the price. I have had many other compressors and this is a good one but not as good as some others. Get yourself one if you got the cash or try one at the shop. You may like it. It colours the sound a bit too much for me. I prefer my old modified CS3 really.

This is an update to my prior post. I have now purchased a 1974 Dyna Comp in a bud box. Though it could be voodoo, I definitely prefer it to my current one (70s block logo). This saddens me because I laso have a MXR script phase 45, and its amazing, and have realized I prefer the script versions.... There is a sizeable difference. It could be someone magically played with the trim pot or screwed it up in the other but wow.... Within 5 minutes I was considering putting my other one on Ebay...

Its 33 years old.....

Again 33 years old...

Just wanted to poison the minds of others with the elusive search for the bud box scripts... As if that fire needed more fuel. I really just wanted to share the fact that for me, it was 100% true, and Ive owned and played many!

2 knobs. BUT the sensativity knob is well.... sensative! Actually. the compressor is just VERY strong and quick and the knob, to me, becomes useless after 11 oclock. Of course thats relative to my playing style as well, but very snappy compression.
I have a 1977 block logo and after purchase realized it was true bypassed-NICE! Especially considering this should usually be 1st in the chain. It is everything I expected and more. BUT... I would NEVER use one of the reissues...yuck.

Incredible but COLORED so if transparent is your game- you won't like it. It adds snap and sustain while rolling off the lows set at low sensativity. Wonderful. I don't play funk but I may need to start. I finger pick a lot and this adds pop and sustain- too much if set too high! I am most impressed by it in the mix. It sits AMAZING with out a touch of eq. If you are happy with your tone, this pedal in the right context will place it PERFECTLY... I track guitars quite often and this is just blowing me away. On lead, well I may force everyone to use it from now on and I have an 1176ln and LA2A originals on the rack behind me.

Its 30 years old, with no bottom plate and the logo and text are almost completely worn off. The foam inside has just melted and I removed it with a toothbrush. It is scratched and banged and kicked around and IT STILL SOUNDS ABSOLUTELY PERFECT. These old MXR pedals are worth purchasing REGARDLESS of their exterior condition. Trust me, chances are it will work. And sound like new! Actually better than new cause the new ones suck. Yes its 100% true.

I yelled "help" into the wind.... I heard nothing back.

Its as good as they say. I go strat-mxr dyna comp-cot50-ts9-mxr phase 45-ad900-semaphore trem- 1959 fender princeton and it sounds incredible. My little amp set up is for recording and it delivers like no other! This pedal was the last purchase and it is the icing on the cake. I considered the Keeley and carl martin but went with the MXR mojo- especially because I am in love with my phase 45 which is from the same year-77. This thing is smothered in mojo. I would definitely say to all - THE REISSUES ARE COMPLETE CRAP COMPARED TO AN ORIGINAL. I have played both- there is no comparison.
