2026-June--Pedal-Chain-V3-700.jpg

A super busy month - with plenty of highlights and heatwaves.

 

My house is finally cooling down as I write these last few observations - we’ve had around 10 days of oppressive heat now, and there’s another wave on the way at the end of this week - which makes for very difficult conditions to have sessions with said pedals.

We’re in the final consequence of global climate change now - with increasingly more extreme weather patterns occurring - alternately cold snaps, heatwaves, and torrential ...

My Thermion PowerDrive and PowerMuff have landed, both excellent value versatile gain pedals with plenty of range

Obviously all the PowerBolt Series pedals ship with stock orange knobs - but since I have so many pedals - I need to be able to easily identify what is what - and so I’ve replaced each of those orange knobs with pertinent unique colour replacement knobs.

 

When The PowerBolt Series launched last year - I bought 4 sets of knobs from Love My Switches. I used the Dark and Light Blue ones on the PowerTrem and PowerVibe pedals last year, and the remaining Purple and Hot Pink / Violet were perfect ...

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 ...

This has turned out to be the largest category for 2025 with 38 pedals in this selection. As I favour those pedals that I own first, and then the more pedalboard-friendly editions - inevitably there would be some casualties for the year. With the most significant of those being the larger format Meris Enzo X, and the Polyend MESS Multi-Effect Step Sequencer. I know there are some who favour each of those - but they just aren’t targets for me personally.

 

 I always talk about having a lane - ...

In some ways May turned out to be a little uneventful! I was due to visit Hello Sailor Effects down in Gosport, but that got pushed back to next month - so the only event of note is tomorrow’s Leeds Pedal Show - which takes place from 10:00 to 15:00 at the Northern Monk Refectory - in the former The Old Flax Store building! Supposedly 20 minutes walk from Leeds Station, and less than 10 minutes in a taxi. I will of course have my show report up for Monday!

 

May was a lot about pedal roundups...

My Thermion PowerTrem and PowerVibe have landed - and they both sound fantastic!

2025-GPX-Thermion-Power-Bolt-Seires-New-Knobse-700.jpg

As soon as I saw Thermion’s PowerBolt Series I immediately thought I would probably acquire a few of those - and I would likely need to swap out knobs to be able to be able to easily identify each one on the fly!

 

I also slightly mis-identified the PowerVibe in my original take, and kind of wrongly decided that I should go with the light blue knobs for chorus - while Uni-Vibe is usually associated with Black or Purple even - but Flanger is also a kind of Purple - and those MXR style knobs ...

2025-GPX-Thermion-Power-Bolt-Seires-Trem-and-Vibe-700.jpg

Somewhat reminiscent of the JHS 3 Series - we get a new €125 affordable yet high quality compact series of 3-knob, dual-mode pedals - where the range starts off with a pair of potent and versatile modulations. Both the new pedals have the same variable controls and labels, but with distinct Mode legends and specific monikers.

 

I really like the textured facia here with the subtle lightning motif (PowerBolt) - which further elevates this series above most other affordable ranges - in terms of...

2024-GPX-Thermion-Breathe-700.jpg

Thermion combines an 800ms Analog-style Tap Delay, smart Dual Reverb, and +15dB Boost for its super handy Breathe Multi-FX / Spatial Effects Pedal.

 

This project evolved I believe as a much requested companion pedal to Thermion’s potent Zero and Freeway floor-based amps (the Freeway in particular) - both have featured on this site. Where the Breathe gives you full granular control over your Time-Based Effects, with some further smart dynamics in play.

 

And those smart Dynamic elements ...

2023-GPX-Thermion-Freeway-700.jpg

The FREEWAY is actually a sort of shrunken down and evolved version of Thermion’s ZERO Amplifier - minus the Power Amp stage, and with some extra features for the modern player. Its key attribute is how you can pretty much plug it into anything - analog / amp / DAW - without the need for any additional interface.

 

As the above visual highlights - this features a version of the ZERO Analog Amplifier with further Analog Speaker Emulation, and an expanded Digital Reverb section from the ZERO - ...

As you can see from the flurry of activity during the last week of the month in particular - April has seen the culmination of 3 very significant projects  - which is mostly reflected by the end-of-month Pedal-Chain snapshot.

 

It was not as if I was short of an overdrive or two, having around 150+ to-date to choose from, but I always felt I was missing a few classics, and in the last couple of months in particular - I made a real concerted effort to make my reference collection fully ...
