mooseherman's review"Really neat multi-band bass compressor"

Trace Elliot SMX Dual Compressor
This is a compressor for bass. While I haven't always felt the need for a compressor, I've noticed that dynamics were pretty lacking with my current bass rig and decided to try this out. It is a compressor that works on both low and high end compression, thus giving you more freedom in tone and dynamics. It's an analog pedal, isn't rackable, and can't be edited on a computer. It has 1/4" input and output as well as a 9V adapter.


Using this effect is pretty easy. There are 4 knobs (input, low compression, high compression, and output). Low and High Compression will add more compression to the low end and high end, respectively. The input gain can be controlled with the left knob, and output with the left. It's pretty basic overall, it's just that for me I had to decide whether I wanted a more compressed low end and a freer high end or vice versa. Eventually I found something I liked though.


I like to use this with my Jazz bass, as well as my P-bass. With the jazz bass, it's better to compress more of the overall signal, where as the P-bass requires more low end compression than high end. Either way, the effects are great. It's perfect for songs that need to remain consistent dynamically, even if the parts don't demand that from the instrument. Basically, a high riff can come out the same as a low end thump volume-wise, or you could just make sure that you don't get too quiet at one point. It's a really smooth compressor because it doesn't squash too much, and it saves tone really well.


I've seen more and more bass pedals that will adjust the high and low frequencies seperately, and I'm finding that I really prefer those types of bass pedals as they can prevent the signal from getting too muddy. This one is a good example of that. It helps you retain power and tone without being too loud, and can help balance a band's live sound out too. It's not too expensive so I'd try it out if I were you and I found one.

Trace Elliot SMX Dual Compressor
This is a compressor in the format "pedal". Format pedal ... In fact it is quite "big" especially broad. It should be a boss pedal 2 times width. This should be taken into account if it is used on a pedal. I personally had the laying on of the amp at the end of the loop before "input" input. Of course not rack!
on the other hand in very thick metal, a real tank that is not afraid of falling!

It is designed for low priority, but it can be used with other intruments given the quality and transparency of the effect.
This is a totally analog pedal. For connectivity: simple like any pedal ==> input and output!
Of course, the effects are not editable, but the advantage is that the knobs do not move to use.

So resume ... It is a dual-band compressor! Clearly, one can choose to apply compression to the entire sound spectrum (bass and treble) or only to "low" frequencies. This is very useful in the end! I'll explain later ...

So there is a switch that activates the effect and another that enables compression frequencies "acute". Then there is a knob for input, a setting for "low" compression scales (I then explained!) A compression of "acute" and finally the output level adjustment.
In short! Ultra simple, efficient, we go to the basics!

The downside of this pedal (without being one in the end!) Is the power that works in ... 18 v! Very difficult to find an adapter! The only known was that produced by Trace, but very difficult to find even in Cygnus!

on the other hand you can use two batteries 9 v and then it works fine!
And the good news is that the batteries last for about 75 hours! So much that consumption is very low ... If you do the repeated 3/4 hours you will have a twenty repeated before you ...
I put 9/10 because of the bp power supply.


The manual? I read it but frankly it is not much use! Better to use his ears!
To use it is very simple! you plug the jack out of your bass, pedal, pedals ... Then you adjust the input level. You have next two knob level indicator with a three color: red, orange, and green (like traffic lights!). Red, must be mounted level. When you're in the green, it's good, optimal level! is to be tested with a "standard" attack game (pick, finger, slap ...). once this set (note that you can do in silence the output level is 0). Then you adjust the output level that is desired. Note: it can be used as a booster. This increases the input level into the amp.
Finally, you set the compression level. There is more "subtle". as it is very transparent, you can feel it is useless to start! However, when playing with everyone we realize that the sound is clear and precise, it actually comes out of the mix! It is mostly on large attacks to avoid saturation, noise nuisance ... This will keep a very clean no matter what you play sound.

Personally, I use almost exclusively compression at low frequencies because the highs are less troublesome uncompressed in a "normal" use (and stand very well for rock, pop, blues ...). on the other hand I enable compression on acute when I play slap, tapping, etc. ... This avoids the "pop" or unwanted pops too violent or disturbing ...

I put 10/10 because it is simple, relevant and effective.


For sound: it is the same transparency. It does not alter the sound of bass, but it avoids the "annoying" sounds or too rough drafts can sometimes feel when we play as a group. In addition it also helps boost the sound! So we can have a very powerful sound without busting the ears of others. Very good it!

I think sincerely that we are close to a studio compressor. It really keeps his sound while having a real "clean" in the sound! Many compressors tend to "crush" the sound and it's really hard to use.

The strength of this effect is mainly the balance. In fact, this button allows you to boost or bass or treble, or mix the two. I use it in pieces (ie I want a snapping sound or lower). as I do not change my basic EQ on the amp! It's really well thought out and especially to modulate his "son" in 2 seconds! I love it!
More interesting than actually EQ pedal as the wheel can be adjusted in the moment that we want.


I use it for around six months. Since it is connected continuously repeated, concerts ... Even if I speak in totally different groups, there is still an indispensable tool. This is the kind of effect that when you put one says ... "Yeah?" but after 10 minutes, it is removed, and there ... Miracle! We said it was just hell before! It quickly becomes indispensable.
I've used other compressors before. The only one who was in the same spirit is the multi-comp EBS. For others, it was either not enough or too much. With this one we are in a compressor "high end" of very good quality, which magnifies the bass sound rather than distorting it.

Manufacturer does more, it's just hard to find in Cygnus! Those who have a guard!

We love: - transparency / efficiency / Side two "flexible" band / the hyper-solid construction / the balance knob.
we hate: Feed in v. 18! Albeit with two batteries that last 75 hours ...

The ratio Q / P: actually € 90/100 OCCAZ it may seem expensive. But when you see his qualities, and especially the "indestructible" side of the machine, we see the essential fast side of the machine, well ... finally

Personally, looking back, I do not regret much, except for not having before!
It's your bass sound before ... And after!

2-band analog compressor pedal steel in a super solid.


Should try some buttons.


A friend gave it to me some years ago.
I thought it was just for slap and as I'm more Rock / Jazz, I had stored for years.
And then I retried a month ago.
I put the input at 12 o'clock, the two cuts to 13H to 12H Tone and output to 13H and there I found the sound very good, more punchy, more sustain while keeping the basic sound of the bass !
And no breath.
Basically, I rediscovered the pedal.

I now put all the time and I not change the settings.

I play a Fender Precision US, a Litle Markbass Mark II and a BBE Sonic Maximizer in the effects loop.


Ben is finally back in my basic stuff ...
Good sound, good compression and super strong.
