Pettyjohn Electronics revives its Core Series - now 'Core X' in larger 1590BB style Raw and Engraved enclosures with an extra 5th Tilt-EQ knob

I recall the original Core Series very well - and picked up those 4 original compacts - per the below original range visual. You had the Edge, ODI, Rail, and ROUS (per bottom row of visual) - where 3 of those have now been revived and enhanced.

 

Pettyjohn then did a number of additional very limited small batch custom compact editions - which covered most of the same territory as these 11 new editions. I feel a couple of these might be brand new - certainly the Moss X Fuzz. ...

2026-May--Pedal-Chain-700.jpg

May has been a little bit of strange month - lots of delays really, and waiting for pedals to land.

As inevitably happens most months - much was delayed this month, and I was unable to complete some of the larger articles - they will need to wait until next month, there’s certainly lots of projects in progress. Where new and imminent arrivals kind of scuppered several intended projects - hopefully they can be completed in June.

The first event I’m attending this month is tomorrow - as a micropub ...

Colortone releases further perfected 4th edition of its killer versatile all-rounder Parasite Full Spectrum Everyday Overdrive

One of my favourite super-versatile overdrives get a new edition / makeover - to bring it up to date with the latest design phase of Colortone Pedals. The Parasite gets its name from the definition of its unique JFETs - which are described as ’... sizzling with parasitic feedback’.

 

4 JFETs make up the core soundstage - which is further served by wide ranging Active Post-Drive Low and High EQ’s, as well as the super smart Pre-Drive Bright Boost and Bass Boost stitches - where the latter is ...

A slightly uneventful month in many ways - just the one event - the excellent sophomore Leeds Pedal Show - where I ended up picking up 3 pedals.

 

Some killer releases during the month, with a strong final flurry to make up the 10 notable article highlights. I’ve been very busy all month - and plenty of work has gone into this as usual, while there was somehow fewer large-scale rundowns and marquee features - more of that next month for sure.

HIGHLIGHTS for APRIL :

The Second 'Gain' Chapter of Thermion's PowerBolt Series is out - with the super versatile and distinct analog PowerDrive Overdrive and PowerMuff Fuzz / Distortion

Thermion famously started off its affordable €125 PowerBolt Series back in May of last year - with two amazing Modulation pedals - The PowerTrem - in part based on JAM Pedals’ Harmonious Monk, and the PowerVibe - a superb compact take on a Shin-ei Uni-Vibe - not nearly as expansive as DryBell’s Vibe Machine - but near enough as flavourful. I was hugely impressed at the time and quickly acquired the pair of them.

 

This time around I’m a little behind the curve - as the pedals have already ...

The Wilson Effects Capstone Overdrive is every bit as Sweet and Transparent as the demos indicated

2026-GPX-Wilson-Effects-Capstone-Drive-SK-700.jpg

So my Wilson Effects Capstone has landed, and it’s exactly as the demos indicate. It can be incredibly subtle and exceptionally transparent. And has an inherent sweetness to its output. You really need to crank it to get it to reveal its more textured side.

 

With the MOD switch to the left - things remain so transparent and subtle - it’s so incredibly transparent. While I quite like to get some mix of harmonics into the mix - which involves cranking a number of the dials.

I so love the Spaceman Effects White Light Dealer Editions - that I had to add another Rumblefuzz II to the capsule collection!

For me - these Dealer special White Light editions - are some of the prettiest varieties Spaceman has released to-date - with the white-out / snow-blind livery and striking cyan / teal LED’s - just gorgeous. I was missing the Atlas IV and Apollo VIIb - and Cream City Music and Axe and You Shall Receive were enormously helpful in getting those shipped to me in short order. I then spotted that my friend Scott at Axe and You Shall Receive also had a White Light Rumblefuzz II remaining - and I just...

I got heavily involved with Pettyjohn / Stephen during their MKII Era - which saw further consolidation of the main ’Foundry Series’, and the introduction of a more affordable, more compact ’Core Series’.

 

Over that period I acquired 4 of each series - including all of the Core ones. It took me a while to understand the nature of how Stephen works - which is always part custom-shop - and there are always additional custom Mods on offer for each pedal - which makes acquisitions more ...

Kevin Wilson’s Capstone Foundation Overdrive is just over a year old now - and I totally missed it the first time around. It’s thanks to a very recent Mike Hermans demo that I’m finally wise to this one. I liked the demo so much that I sprung for one instantly. These are very reasonably priced at just $155, and even better there is a ’SPRING’ promotion on now which takes off a further 15% - for an absolute bargain!

I initially covered this subject in mid-January - where I announced the arrival of the Tru-Fi Minis. 5 were initially made available, but at my time of coverage only 3 had reached the UK. Since then Teddy has released 3 more variants - and now 8 Minis in total have been released.


All 8 Mini Editions are now at Joe’s Pedals in the UK - priced at £199 each, where the original Tru-Fi USA price is $199 - all very fair.

 

Each of the 8 pedals are equivalent or better than the original larger size...
