2021GPXKeyToneStacks700V2.jpg

Different Tone Stacks have endlessly fascinated me over the years. Exactly which Tone Stack each builder chooses to deploy on each of their specific gain pedal/s - how complex and impactful (range, focus, taper etc.), as well as how the overall frequency profile is default calibrated at the mid-way / noon mark. There are dozens of different variations across all the different compact edition type pedals - which serve as my visual references here. And of course some Tone Stacks are particularly ...

2021GPXSKPedalChainUpdateMayRevised700V4.jpg

May turned out to be another pretty busy month as far as new releases and the overall collection is concerned. I personally acquired around 20 or so new pedals - with some further acquisitions not having landed yet.

 

Obviously a fair amount of new Overdrives and Phasers in particular - while May covered most of the key pedal categories in one way or another. And most of the pedal-chain additions for the month have been reviewed or touched on in some way previously - with the exception ...

2021GPX10BestPettyjohnElectrnics700V4.jpg

Those more sharp-eyed among you will have noted that I’m currently engaged in exploring the Pettyjohn Electronics range - sort of one or two pedals at a time. And this would seem to be a good point within those proceedings to share some of my findings thus far.

 

As I’ve relayed elsewhere, I was initially highly confused by Stephen Pettyjohn’s output in that all the Foundry Series pedals were offered with a number of ’Upgrades’. Making it seem to me that the...

April has been another pretty formidable month - and at last I have the CopperSound Triplegraph in my hands - which presented some challenges in being accommodated within the rig. I’ve had to significantly adjust and rejig various elements and areas - including of course the format of the above reference visual.

 

This indicates the physical position of the Triplegraph at position #14 in terms of physical pedal placement - where it sits just before the CBA Automatone Preamp, while ...

2021GPXPettyjohnEdgeChime700V2.jpg

The latest Pettyjohn Electronics Pedal is the Core Edge Low Gain Overdrive (Gørva-enclosured). This pedal owes its pedigree to Pettyjohn’s best-selling Chime Overdrive - which per the visual can really be considered the sort of Senior version of that circuit.

 

Obviously we have slightly different controls, and at default the Chime is loaded with Yellow LEDs - which are designed for relatively quick-onset breakup. While the default Edge comes with Blue LEDs designed for ...

March seems to have been unusually busy on all sides really, particularly with the day-job’s annual keynote event. Generally this year has been off to quite a moderate start, but that seems to have accelerated somewhat during this month.

 

It’s been a mixture of January NAMM pedals materialising and spring-time special offers, all of which contributed to a somewhat bumper month - with a record-breaking for me 29 acquisitions, prior to that the record stood at 26, while that ...

Reader Charles H requested that I do a roundup of Clean Blend Overdrives - which resulted in the following selection. Most Bass Overdrives have Clean-Blend by default - while all the ones I have selected here are more specifically Guitar Overdrives. I personally don’t find myself needing to use Clean Blend so much - but I can totally understand why so many players find this functionality useful or even essential. The Blend knob is variously labelled Blend, Clean, Dry and Mix. I’ve ...

2021GPXSKPedalChainUpdateFeb700V3.jpg

I would like to start by apologising to those builders who didn’t get a pedal featured in Wednesday’s final 32 Key Guitar Effects Pedal Types article. Know that I hold you all in the highest of esteem - and that said overview is/was simply a somewhat temporary and fleeting snapshot of my current preferences on that day - with a particular emphasis towards versatility and variety delivered by a single pedal. So some pedals are typically more narrowly focused and specialist, while ...

Before I get into the meat of the review, I thought it best to put everyone fully in the picture as regards my evolving appreciation for Pettyjohn Electronics. I freely admit I am largely somewhat late to the party as such, in part due to my earlier confusion about parts of the brand’s modus operandi. While I have now of course acquired each of the brand’s most recent ’Core’ series - RAIL Fuzz, ROUS Distortion and ODI Overdrive.

It is fairly evident that my favourite pedal genre is Fuzz - seeing as that of all the pedals I added to the collection this year - 80 of those were Fuzz varieties.

 

This particular selection consists of 31 pedals across different sizes and sub-genres. And of those 31, I personally own 22 of them. All the remainder are of course on my wishlist, these are :

  • DanDrive Secret Machine (I own Secret Weapon edition)
  • Dusky Electronics Augustus Octave Fuzz
  • Fjord Fuzz Fenris Super-Fuzz
