Mr Wu has expanded the envelope further - another evolved and improved MGAT-1 Pedal is incoming - the Marshall EVO Edition Sinvertek Real Amp Abstraction

I already thought we had witnessed Peak Full-Range Marshall back in 2022 with the original MGAT-1, then Mr Wu significantly improved that circuit in 2024, and the new one promises to be even better!

 

So far we’ve only had a teaser on Instagram - where I got the EVO pic from - while there is no web page yet or much in the way of further details.

 

Like the MGAT-5 - the first batch will contain especially mojo components - so it’s worth getting involved early on.

 

The actual control ...

And here we have the GRAND FINAL- with all 36 Award Winners from the Group Stages - across all 5 categories!

 

The first two places have kind of been obvious for a while, where the 3rd / BRONZE position was actually the hardest to decide on - it was between the eventual recipient - the Tubesteader Gainlord, Boss’s XS-100 Poly Shifter, Blue FX Devices Fuzz Fields and Gamechanger’s Motor Synth - all of whom would have been worthy runners-up - while in the end I went for the one that overall ...

And so onto the Distortions of the year - the smallest group stage this year! There’s no particular logic as to why there are just 20 Disortions this year. There were a further couple of acquisitions that I was disappointed with - and I deliberately left out of this selection. It’s mostly a case of what appeals each year - and evidently there weren’t that many appealing ones beyond those I acquired. I’m not aware of any particular ones that are still in the wind. The last one in was the ...

Another super busy month for me - particularly towards the end - with numerous large scale articles out this week. That also coincided with my busiest week of the year for my other day job. Meaning that I was up until 4-5 in the morning every day - just to keep up with my commitments.

I was already somewhat shattered and burned out before I even got to this super busy period - and it’s a relief that all that work has now been completed on schedule.

I’m especially proud of my work on the Bucket ...

So we’re at that time of year again for another Full Metal Racket Rundown. I meant to have it coincide with halloween - but was so inundated with new releases work - that I really struggled to fit this one in. And it now appears a month later than I wanted it to - but still very much at the appropriate end of the year!

 

As is ever the case - this selection continues to evolve over the years - and inevitably some previous candidates get bounced for more impressive newer variants.

This feature has been a long time coming. I have somewhere around 60 to 70 Marshall-style Pedals in my collection - while this selection mostly features Dual-Channel or Drive + Boost Pedals - which cover you both for Marshall Plexi and JCM800 flavours - actual and ballpark.

 

I landed 4 of these this year - the Crazy Tube Circuits Heatseeker, Flattley Outlaw, Fortin Kali, and Tubesteader Gainlord.

 

We have 4 distinct types of pedals here across 4 format sizes (Compact / Mid-Horizontal / ...

2025-June-GPX-Pedal-Chain-700.jpg

June was influenced by a few key events. Obviously the Leeds Pedal Show had a massive impact on me - and I picked up 9 pedals at that show - all excellent, and later picked up a Hudson Electronics AP-II Broadcast. So the reach of the Leeds Show has been massive - particularly the brace from Emmergy FX and SoundLad Liverpool. Then also my visit to good friends Hello Sailor Joe and Glyn - which resulted in a further brace of superior pedals, all featured on the blog this month.

2025-GPX-Sinvertek-MGAT-5-Update-700.jpg

I’m getting somewhat irked by the people who criticise the appearance of this pedal - with some citing it as the worst design ever! - which is wholly unfounded and dangerously ignorant in the circumstances - the nature of the control topology is limited by the small format and the various internal elements that make up the circuit - the development of which is usually a series of compromises to fit within a prescribed form factor. If you can’t handle the enormous capabilities that come with ...

Further details emerge on the MGAT-5 Sinvertek Soldano SLO 100 Real Amp Abstraction - on the cusp of early orders being shipped out

2025-GPX-Sinvertek-MGAT-5-Labels-V2-700.jpg

So - further details have emerged on this latest Sinvertek MGAT-5 creation - which now makes a little more operational sense to me.

 

I think I’ve understood most of the acronyms now and what they stand for - where they include S.R.A.A. (Sinvertek Real Amp Abstraction), TO.DE (Tone Density), and T.S.N (Tone Shaping Network / Frequency Focus).

 

The pedal features 15 controls as far as I can gather - 7 x fully variable knobs, and 8 x 3-way toggle-switches, including a  Channel Selector. That...
