So a follower on Instagram asked me to do a piece on which pedals had Sweepable mids - meaning really semi-parametric mids - with one control for Mids Frequency, and another to Cut/Boost that Frequency.

 

I thought there were a lot more than those that I finally uncovered. It’s mostly distortion pedals that have 3-Band EQs, and so it stands to reason - that it’s mostly distortion pedals that have parametric mids too.

 

While there is also a now long discontinued series - by Big Tone Music Brewery (BYOC sister brand) - called the EQ’d Vintage Series - each of those 10 pedals had 4 EQ Controls on 2 dual-concentric knobs - Treble and Bass, and Mids and Frequency. I own 9 of the 10 varieties released - and thought I should feature a fuzz, overdrive and distortion from that series. The only one I’m missing is the Silver Overdrive (Silver Klon), where the Golden Pony Overdrive (Gold Klon) carries both Gold and Silver voicings - so the Silver edition is really surplus to requirements. The EQ’d Vintage Series was woefully overlooked and discontinued after fairly little interest following its launch - while each of those pedals is superb - made with the very finest original circuit components - including several now NOS and impossible to get parts!

So I trawled through various resources, including my own site to find anything I could that would fit into this category - note that I decided to limit it to compact pedal editions. And like I said there really weren't that many. I came across several that had 3-way switch selectors for Mids Frequencies - but excluded those as they weren't properly 'sweepable'. And certain ones that I tought fit the pattern actually had somewhat different controls.

 

So in truth there really don't seem to be that many around - and funnily enough all the ones I could uncover are all already in my collection - meaning that I own each of these 12, plus 6 further BTMB ones as per the above visual.

I'm genuinely surprised that there aren't more overdrives with this tone-stack - traditionally they are most composed of just a single Tone knob, or 2-Band EQ really at the most.

Abominable Electronics Pedalboard-friendly Chaotic Evil Ned Distortion - discontinued - $250

close

Controls - Freq L, Freq M, Freq H, Low, Mid, High, Volume, Distortion.

 

I almost missed out on this edition as Patrick only made a single batch of Black and Orange edition of this pedal - and then a variety of colourways that did not particularly appeal. Fortunately I was able to pick one up second-hand - courtesy of Reverb.com I think. Some of you will remember the original not-pedalboard-friendly version which had 11 knobs, and was about as long as a skateboard. A cool collectable for sure - but far from practical. This pedalboard friendly edition drops the 3 resonance controls per band and saves on about 3/4 of the real-estate. A really cool HM-2 variant - especially in these colours - and sounds pleasingly brutal - definitely had to be in my HM-2 capsule collection, and I was delighted to have snagged one in the end.


Boss MT-2 Metal Zone High Gain Distortion - $120

close

Controls - Level, High / Low, Middle / Mid Freq, Distortion.

 

Probably the most popular metal distortion of all time - and Boss's second best seller of all-time after its DS-1. This is most people's first idea of a pedal with parametric mids. The original / standard version can be a little fiddly to dial in - as the frequency dial is so sensitive and requires proper micro movements - a little like safe-cracking! However, some patience and perseverance yields superior tones - particularly on the Waza Craft edition, and my favourite Keeley Twilight Zone Mods edition.


BTMB EQ'd Vintage Series American RamFuzz (Big Muff) - discontinued - $199

close

Controls - Treble / Bass, Mids / Freq, Level, Sustain.

 

And here we have the first of the BTMB EQ'd Vintage Series - a superb version of the 2nd Edition Big Muff Pi Ram's Head variant. I would have featured the original 1969 Big Muff Triangle variety with those same now super rare 2N5133 Transistors - but no demo exists for that. As with every pedal in this series the top 4 EQ knobs / controls are the same - and include Mids Cut / Boost and Frequency. Some models have an additional voicing toggle switch - as is the case with the other 2 in this selection. If you want a fully authentic sounding original Big Muff circuit with extended range - then this is surely your weapon of choice - just a brilliant pedal all-round, and a mystery why these did not catch the public's attention at the time. Possibly a little too far ahead of its time!

 


BTMB EQ'd Vintage Series British Overdrive (BB)) - discontinued - $199

close

Controls - Treble / Bass, Mids / Freq, Voicing : Vingtage (Blues Breaker) / Crunch (Plexi), Level, Gain.

 

A quite superb MIAB style overdrive - much superior for me versus the recent Marshall reissue. This pedal also gives you two voicings - with the switch to the left delivery JTM45 / Blues Breaker sounds, and to the right delivering killer Plexi flavours. This was the last one I got hold of - where my good friend Scott Hager (Axe and You Shall Receive) put me in touch with his friend Keith Vonderhulls - Mr BYOC / BTMB himself. I think I got 8 of this series from Scott - who still weirdly had some in stock, and just the British Overdrive direct from Keith where he discovered he still had a couple left in storage. Each of these pedals is fantastic, and I feel very privileged to pretty much own the full set.


BTMB EQ'd Vintage Series Classic Distortion (Rat) - discontinued - $199

close

Controls - Treble / Bass, Mids / Freq, Voicing : Vintage (Original) / Turbo (Red LEDs), Level, Gain.

 

And another fantastic BTMB classic - based on that quintessential ProCo Rat Distortion - featuring wholly vintage original components, with original LM308 voicing, and then the addition of 2 Red LED's for the Turbo edition / voice. Everything just works really well on thes pedals and you can dial in tones that you can't really achieve with just the basic original 3 controls. These BTMB EQ's Vintage Series were woefully overlooked at the time - and now most of those original components are gone - so it's not really an exercise that can be repeated. Actually a fantastic milestone in pedal innovation for its time - I guess there were just too many people then that were slavishly attached to the minimal 3-knob formats of the time. These are actually all a significant step-up!


Chase Bliss Condor Analog EQ / Pre / Filter - discontinued - $349

close

Controls - Gain (Ramp), Freq, Volume, Bass, Mids, LPF, Bass : Minimal / Moderate / Most, Mids Q : Wide / Moderate / Narrow, LPF : One-Pole / Two-Pole Moderate / Two-Pole Resonant, Presets : 1 / Manual / 2, Bypass Footswitch, Drive/Hold Footswitch. [+16 Dip-switches]

 

A supremely versatile 'fixer' pedal which can carry out all manner of different duties - as an EQ / Tone Enhancer, Evelope Filter, Tremolo, and Gain Machine - to name but a few. I think I'm one of those rare souls that actually uses the Condor primarily as an overdrive. But that's an area it really excels in - with a really smart EQ - including of course separate Mid and Freq controls. You get quite a bright and really crisp breakup - for a quite distinct overdrive tone - where this pedal has frequent rotations on the board in that capacity. Most other people seem to use this for function that I already have covered on the board by other pedals - but as an all-round gain and tone-shaper - this pedal is superb - and I was really surprised to see it discontinued!.


DOD Boneshaker High Gain Distortion - $170

close

Controls - Distortion, Depth, Level, Low / Low Frequency, Mid / Mid Frequency, High / High Frequency.

 

Now recently re-issued as part of DigiTech's / DOD's revival - I think everyone was delighted to see these pedals in action. While this one has as many fans and detractors - similar to the Boss MT-2 - there the Boneshaker has even more controls at your disposal. It seems that the average 'Joe' can't properly cope with Parametric Controls. But then you're often trying to cram a very extensive mids sweep into a fairly diminutive rotary pot - so it can for sure to be tricky to dial these in at times. I think I prefer the core MT-2 voicing - while this one is just as adept at carving out interesting tones.


Empress Heavy Menace High Gain Distortion - $250

close

Controls - Gain, Weight, Output, Low ±15, Mid ±15, High ±15, Gate Threshold, Mid Frequency : 200Hz > 2.5kHz, Channel : Lite(ish) / Heavy / Heavier, Gate Footswitch, Bypass Footswitch.

 

Despite a somewhat weird and lacklustre launch (which I was excluded from), this is actually a really decent heir to the former larger 2-channel Heavy Distortion. It does all the same things - with a more variable gate and mids sweep - in a much better and more practical format. I always found it a little odd / limiting that both channels on the predecessor shared the same High and Low controls - and this pedal adds more granularity all round - and sounds just as potent as the original. There are some even more potent high-gain pedals out there - like the Tone Ink Raven, while the Empress Heavy Menace is still mightily impressive and has enormous versatility - I'm glad to have it in the reference collection despite the circumstances - I got mine from Thomann - as they were the first to have it stock in Europe - the UK dealers were a little slow this time around!


Hardwire TL-2 Metal Distortion - discontinued - $129

close

Controls - Level, High / Low, Mid / Mid Frequency, Gain, Voicing : Tight / Loose.

 

Some people say this was the equivalent of the MT-2 Waza Craft - long before Boss had that idea. This essentially has a very similar control topology - with an additional Voicing switch. It's not quite as rich and fat sounding as the Boss - and can indeed sound a little wiry at times - but again with some patience and due diligence you can dial in some really decent tones. It's not really a MT-2 competitor as its core character is quite different really - although it has that same versatility.


JHS Pedals Paul Gilbert PG-14 Distortion - $199

close

Controls - Volume, Mid, Drive, Tone, Mid Freq, Push (Pre-Gain).

 

Paul Gilberts's signature JHS Pedal is another compelling distortion while not quite as versatile as you might think. Possibly improved by having the main Tone knob as a Tilt EQ. I quite like this - but it's not ended up as one of my favourites. Sometimes it's the case with signature pedals that they're overly calibrated to the artist's precise requirements - and are then slightly less suitably for general use. You can get some great tones out of this - but I have several other distortions whose core tones and timbres I much prefer.


KMA Machines Wurm MK2 HM-2 Style High Gain Distortion - $230

close

Controls - Volume, Voicing: HM II / Both / KMA, Terror (Distortion), Highs, Hi-Mids, Low-Mids, Lows, Internal Frequency Trimmers for Lows, Lows Mids, High Mids, and Highs.

 

A magnificent engineering achievement in taking the formerly 1590-BB edition and reducing it down to compact proportions - while adding the formerly internal voicing switch to the exterior. The one thing that is the same for both larger and smaller pedal is that you have internal frequency trimmers per each frequency band - so the knobs on the exterior cut or boost the frequency set on the internal trimmers. A really impressive HM-2 type which shares the best compact HM-2 with the HM-2W, Abominable Evil Ned and Bardic HM-Demon - each has its own advantages and all sound fantastic and yet somehow distinct too!


Menatone The King MIAB Overdrive / Distortion - $219

close

Controls - Level, Drive, Gain, Hi, Mid, Lo, Voicing : Modern / Vintage, Mid EQ Freq : 90's / 60's / 70's.

 

Both the recent Menatone Kings are killer - this on and the King of the Britains - and each has a slightly different style of EQ - where this one has quite an unusual Mid Sweep Frequency control - which is labeled by the Marshall Amp eras, 90's, 60's and 70's which all had slightly different Mids frequency profiles. It's difficult for me to decide which of the two 'Kings' I prefer. This one has a more granular EQ, where the King of the Britains has an additional Boost. Both really potent and versatile compact MIAB pedals - which have each been in fairly frequent rotation since they arrived.


Final Thoughts

2023-GPX-12-Parametric-Mids-Compacts-700-V2.jpg

I obviously really love pedals with Parametric Mids - as I seem to own every conceivable candidate - or 18 in total for this compact format. There are several Mid-size boxes which have this style of EQ too - perhaps I will do a follow up article and name those if there is a desire for that too - not sure on those numbers yet - but of course always good to know!

 

As I mentioned in the intro these types of controls are more typical on Distortion and High Gain pedals - and very rare on Overdrives and Fuzzes. Overall I feel this is a cool compact capsule and this contains several of my favourites or near favourites.

 

As I noted too - some pedals missed out where they had less granularity courtesy of a 3-way switch or similar with more limited frequency options and not the full sweep.

 

Obviously if you're looking for high-gain pedals you have lots of options while for Overdrive and Fuzzes - you're mostly in and around the BTMB EQ'd Vintage Series.

 

I'm sure I've overlooked one or two - so do let me know in the comments below - noting that these are very specifically Compact enclosures - I expect some will still ask where the KMA Logan and KMA Chief Disruptor are - but those are both mid-size boxes - and so don't meet the criteria here - but will for sure be included in the mid-size follow-up if that is a go.

 

Parametric Mids really allow you to refine and fine-tune your tone - and mids frequencies can be so important to certain genres - including any and every Marshall style pedal and Big Muff! They really help on Rat and Tube Screamer circuits too!
