As is always my way - I’ve taken time out to do a proper infographic of the new MGAT-1 variant, the 3rd of that line, and the most ’dialled in’ one yet. The topology looks the same from a distance and indeed we have the same number of knobs and switches, while uniquely to this version we have specific Amp types and values ascribed to each amp profile.

The pedal essentially covers 5 key Marshall amps - right through the gain range from relatively mild for the JTM45 to absolutely blistering high gain for the JVM variant :

JTM45
SLP Super Lead 100W
JCM800
JCM2000
JVM

And this time Mr Wu has made it easier for us to dial in those specific amp tones - putting more specific characteristic variables / settings at your disposal.

He’s also included several references as below for 4 specific varieties of Marshall Amps.

So in some ways there is less variability - but importantly it easier than ever to nail those precise classic tones. And there are a lot of further controls for you to go beyond those tones and create your own sound - but with those core foundations as you base.

Specific Amp Settings

In the latest edition Mr Wu has built more of an on-rails pedal - with very specific switch settings for each model. We have been provided with settings for 4 of those key amps.

First Impression

My good friend Michael Aschoff describes this new edition as being 'Super Gooey' and he compared his Evo's JCM800 voicing to the JCM800 Axe-Fx III model - and the Evo of course bested that.

I don't know how Mr Wu does it - I was convinced that the very first MGAT-1 was peak Marshall in a box, but then we got the even better MGAT-1 Golden Era, and now we have the still better MGAT-1 EVO. I sometimes wonder if Mr Wu is influenced by Apple's business model - and deliberately holds back some of his mods for further editions. While each one of these is sufficiently noticeably better than its already stellar predecessor, I've been following this MGAT / N5 line of pedals since 2017 and have all 8 key models to-date. I'm constantly astounded by how the new version can be even better than the previous one that I so loved and lauded. I always feel a little bit sad when a new edition comes along and outmuscles all its predecessors.

This new one is miraculously somehow even more vibrant and livelier than its predecessor - with further improvements to the feel of the pedal in particular. These Sinvertek pedals are so impressive! I have several fantastic MIAB pedals (around 70-80) - in fact I just did an article on that. And yet this MGAT-1 EVO is the best of the bunch in terms of its core amp flavour, dynamics, and range. None of my other Marshall pedals can carry me through the gears with as much aplomb. There's something kind of effortlessly kinetic in the nature of these pedals.

Interestingly my 2 main Sinvertek buddies - Michael and Henry both went for the Red, White and Blue 'Abstractionism' edition - in part citing better legibility. While I've always associated the colour Gold with Marshall - and so I went for the Gold-Accented Great Era Edition.

I seem to have fallen somewhat out of favour as my model number is '12 of 79'. There was a time when I typically got a top 10 serial number - while I've seemingly been in the double digits zone for a while. I'm not sure anyone has supported the N5 / MGAT Series as well as me! You win some, loose some in any case. And actually I'm not really that bothered with serial numbers - while it's always nice to get an early number!

I've only just started using mine - and on the Plexi settings of course. My only niggle here is the heavily - in fact totally gooped PCB. There will be no fixing this if anything goes wrong. While possible those mojo components are better protected under a layer of resinous goop. This is one of the very few brands I'm aware of that continually goops its pedals. Besides Sinvertek I really don't have that many gooped pedals - I can recall my one Trombetta being gooped - I think I have one or two more - but it's not really front-of-mind at the time of my writing this!

If you pop off the back of the pedal - the only thing you will see is a shiny sea of black goop. There's not disputing how well these are engineered - no one is really making pedals at this specific level of range and brilliance besides Mr Wu. And I'm still very glad to be onboard that train!

If you're a fan of Marshall and love pedals - then you will absolutely need to get yourself one of these. Remember to email Sales Manager Tina at : officialsales@sinvertek.com - and she will send you the invoice. I paid $369 + $20 Shipping for mine, and then a further Customs & Import charge of £44.60 (c.$61) - for a very nicely rounded total of $450 (c. £330). I typically pay €469 for Chase Bliss pedals - from Chase Bliss Europe (Amsterdam). So those prices are kind of equivalent largely. Well worth it either way for me!

This is still the greatest MIAB of all time as far as I am concerned, albeit it just has a single Channel output - but with incredible and ultimate range! Magnificent as always!

There are some great materials on the Sinvertek site - you can read up further on that Website!

While as I'm in the first wave of these landing - we have yet to see any manner of demo! I will of course share one as soon as it materialises! Hopefully we will get something soon from Michael Nielsen! The demos for these pedals always take a while typically!
