REVIEW: HomeBrew Electronics Detox EQ

Review by Steve Turner

Signature gear. Who really needs it? Often the signature tag is merely an advertising tool selling hardware that probably bears no real resemblance to the equipment used by the artist whose name is plastered all over the marketing materials. There are exceptions of course… The perceptive reader will at this point be predicting that I am going to suggest that the Detox EQ is one of those exceptions. This is indeed the case, and for very good reasons.

My personal path to finding the Detox EQ was pretty straightforward. I have been using HBE (HomeBrew Electronics) pedals in my live rig for quite some time and have always been very happy with the sound and build quality. I have run their CPR Compressor, UNO MOS boost, THC Chorus and Germania 44 in various environments and they are all keepers.

I am also a fan of Mr. Paul Gilbert. Really, who isn’t? One day whilst trawling the internet for information on his effects rig I noted that he was using three of the same HBE pedals that are in my own rig. In addition he was using a then unfamiliar unit – the Detox EQ. Given I was already very happy with HBE pedals I was intrigued to know what the new pedal was doing for Paul’s sound.

The origins of the Detox EQ are based on Paul’s use of a single channel amp running with high gain and his need to be able to create a clean tone with minimal effort. Paul had been using a Boss EQ pedal for volume cut and tone shaping but found that it added extra noise and the EQ spread was not quite right for his purposes.

The Detox EQ is a very simple concept which HBE have realized in a very elegant and functional stomp box. There are four dials: level, treble, middle and bass. The pedal is powered by a typical 9vDC source (battery or external power). As with all HBE pedals it also features true bypass. It is a great looking pedal too – and we all know how much that matters – the yellow is quite striking and it just begs to be used.

The Detox EQ volume pot can be used as a signal boost to add saturation or as a cut to clean up the tone of raging, multiple tentacled high gain monster amp. The EQ facility also allows some additional tone shaping and the available frequencies are quite musically placed. The EQ dials do not give massive amounts of extra boost or cut to any of the frequencies but can create quite a consistent curve.

Running the Detox EQ with my highest gain amp, a Bogner Uberschall, the results were positive across the board. As a boost the Detox is nice and subtle – not as aggressive as the HBE Uno Mos or other clean boost pedals but certainly creating a very nice EQ shape when engaged. Due to the fact the pedal is so quiet you might be tempted to turn on, dial up and leave on at unity gain for a bit of extra flavour.

As a cut, the Detox gave me a gritty clean tone reminiscent of early Dixie Dregs with a nice amount of attitude in a much cleaner signal than the Bogner high gain channel would usually provide. Working with the two channel Uberschall the Detox running as a signal cut gives me a virtual third channel in between the angelic clean and high class hooker, dirty tones.

Running with a Bassman clone I was able to dial the amp hard to get some really nice power amp breakup and then rein it in back to a more sparkly clean by engaging the Detox with a small amount of cut. As a quick experiment I plugged the Detox into my Pod X3 and found that it added some very pleasing tonality to the digital signal output to my workstation. I think some people would definitely find that it adds a bit more of a natural tone to the digital modeling of the Line 6 and comparable units.

Cutting amp saturation by reducing guitar signal is not a new idea. People have been doing it for years by dialing back guitar volume pots. The benefit and value that the Detox adds is that you can EQ the signal to account for any frequency shifts that might occur based on dialing back the signal – something that can not be done through a guitar on its own. Plus, it happens instantly and the signal boost or reduction is predictable based on your pre dialed setting.

I am very pleased to say that the Detox EQ pedal is another winner within the Home Brew Electronics line of products. It is very, very quiet when engaged and I am considering buying another so I can run one as a cut and one as a slight boost with EQ curve around the mids. The tone when engaged is very articulated and adds a really nice flavour to picked notes and chords alike.

If you have heard Paul Gilbert’s Silence Followed By a Deafening Roar album then you have definitely heard the tone of this pedal as a cut and as a signal shaper at unity gain. This is one of the few examples of signature gear that really lives up to the name of the player and the hardware designer alike.

No, this pedal will not make you sound like Paul Gilbert nor will it magically make your amp sound just like the tones on the Roar album. What it will do is bring out some really nice characteristics of your own amp that you might not be able to achieve otherwise. I would consider it a good pedal to keep in a guitar case for gigs where you are running through gear that is unfamiliar.

If you are interested in how Paul uses this sweet pedal you can head over to the HBE site and check out his personal guide on how to run the Detox. I can confidently say that this pedal definitely does what it says on the packaging. What more can you ask for? Maybe some private lessons from Paul Gilbert? Good luck with that!

NEWS: Paul Gilbert signature HomeBrew Electronics pedal

I was alerted to this by the Random Chatter Music blog: Paul Gilbert posted the following on the Racer X message boards today. 

I am proud to announce my first signature pedal, the DETOX EQ by H.B.E. (HomeBrew Electronics)

I’ve been using this pedal for the last few months and I am officially addicted to it.

Why an EQ? Here’s a detailed answer:

I have always liked to get distortion by playing through a cranked-up tube amp.

I have always liked to get a clean sound by turning my guitar’s volume knob down.

This works really well with some guitars and not so well with others, depending on the pickups and electronics in the guitar. On my Spaceship One tour, my main guitar was an Ibanez Rocket Roll II (Flying V shaped) guitar with two humbuckers. This guitar sounds amazing when it’s cranked up, but it doesn’t get that sparkly clean sound like I can get from the pickups on a PGM (which has a single coil and a 5-way switch).

To solve this problem, I bought a Boss EQ pedal and used it to turn down the “muddy” frequencies as well as turning down the overall gain. The pedal became a virtual “clean channel” and was really useful for cleaning up my sound while performing live.

But the Boss EQ was hissy (even though I wasn’t boosting anything), and the frequencies weren’t set as musically I would have liked.

Recently I have been using several pedals from H.B.E. and liked everything about them. So I contacted the people there to see if they would be interested in building the ultimate EQ pedal for me. And the DETOX EQ was born!

The DETOX EQ is noise-free and has very musically tuned EQ knobs. I used it to make subtle adjustments to my tone on the United States CD, and I’ve road tested it on my European tour. I love it!

If you look at photos of my pedalboard (left), I’m still using my prototype which is a gray box with red tape on it. I got a new one from H.B.E. and let Craig Martini use it for his bass rig. That one is yellow. I’m going to switch to a new one when I get home!

Anyway, whether you use the pedal to clean up, boost, or just tailor your tone, there is no EQ pedal that touches the DETOX in quality in tone. H.B.E. did an awesome job.

The pedal is true bypass, operates on 9 volt battery or DC adapter, and has a list price of $159. Click here for more info from the HomeBrew website, and here for even more info on Paul’s on site.
