Artec Parametric EQ

I have been trying to set up my looper to play backing tracks through a Mackie SRM 350 pa speaker to get enough volume to practice my sax. The volume is fine but the speaker is ridiculously bass heavy and unusable at home.

I have tried taming the bass with a small Behringer mixer which helps a bit, but it's not hitting the right frequencies and it's a cumbersome solution. I had thought about a graphic eq pedal but had doubts that it would be effective because of my experiences with the Behringer. Then I discovered the Artec Parametric EQ and decided to take a risk with it because of its potential ability to target the frequencies I want to control.

It works! It does exactly what I need and is very effective. It's very simple to operate - you can set a boost or cut and then turn the frequency knob until you hit the offending frequency. Then you can alter the Q setting to adjust the range of frequencies you want to modify.

The build quality is good, at least for what I need. I do agree with other reviewers that having tiny frequency and q control knobs with an even tinier black on black centre point marker is a very poor design. It was ok at home where I could hold it up to a bright light to see, but using it live to adjust the tone would be a challenge to say the least.

The sound quality is good and I didn't detect any noise or impairment of the signal going to the speaker. It works well with the supplied battery it is a much tidier solution than a mixer with an external power supply. I don't know what the battery life is yet.

So, in summary, for my very specific requirement it is an excellent solution and the Artec is a fraction of the price of other parametric eq pedals.

I've seen people getting parametric EQs because they have read silly articles on the internet claiming parametric gives you more control than graphic EQ. Needles to say, most of them get very disappointed.
Well, this is NOT a replacement for a graphic EQ. This is a special use tool which will let you attenuate (or amplify) one specific frequency band. Basically an active band-rejection filter.
As for this pedal, well, it does its job and it's the only parametric EQ in a really affordable price range, but it's definitely not professional as it claims to be.
The box is sturdy metal, but the button, pots, and especially the battery door look very cheaply made. The frequency knob is marked 1 to 10 instead of real frequency values and this is quite dumb. The width and gain knobs are super tiny and impossible to grip, let alone read their values. Why didn't they make 4 normal size knobs is beyond my understanding.
All in all for such a price its a good deal, I can't complain. Compared to other parametric EQs this one is dirt cheap and it's a no brainer to give it a go. It's interesting to combine with distortion pedals, you can make humbuckers sound like singles and you can get some wah-y sounds too.

As a single band parametric EQ, it does the job perfectly in order to adjust your guitar tone before the preamp or tweak a bit your preamp sound if you place it in the effects loop. You know, remove muddiness, tweak brightness, add mids, adjust tone when changing from dual to single coil...

But I've ended up using it as a booster as it really nails it. Because of the 4 controls (level, frequency, freq. curve and gain), you can use it as a plain booster (just volume) or a custom booster that can add extra brightness, mid-boost or even a lower frequencies push when soloing without increasing the overall volume too much.

This product is very good, but is no good for the purpose that I bought it:
I bought this product to use as a narrow band bass 'cut', to 'EQ the room' for my PA system, i.e to remove standing waves. The specification is RATED AS CAPABLE OF THIS, at 1/2 octave to 1/4 octave i.e, a 'Q' of 4 to 7. I find this not to be the case. The Q factor is too wide, and to remove a resonant bass frequency from a room, too many frequencies are lost. To prove this, I tested this product at my work on a frequency generator and scope at 400Hz and the Q factor is very wide at the narrowest setting. I would like to say the unit build quality is very good and has low noise and will work very well for anyone looking for a wider band lift or cut, it just doesn't work for me. I will try a bass EQ pedal in the future.
