I have one of these, it is amazing! Probably the most versatile single channel tube amp ever built. You can get everything from ratty Marshal to thick Mesa tones out of it.

That things a beast Leon. With the girth up and the master up it sounded like you didn’t even need the depth control. That IR sounds sick👍

I do love the Atomica in the Axe FxIII and I use the negative feedback a lot with it. Nik is a great guy, I bought a Yeti 50 with some changes a few years ago.

Girth always matters! :))

Pretty cool, Leon. Nice guitar, Sykes is an absolute legend. Your playing rocks as always.

For some odd reason, Friedman and some early high gain marshall mod-ers prefer a low resistor value(and sometimes from the 8 or 16ohm tap) which makes the amp sound dark, "polished", tighter, warmer, refined, according to their own subjective adjectives. I've been doing that low nfb resistor on the 8ohm tap on my early days of modding, but after a while I figured that brighter is better and tighter. It really shows how we subjectively throw adjectives to define sound 😂

I have this amp, for me girth control is a little bit similar to tone control on overdrive pedal. You can use it for how much tightness you need, it adds brigtness to the sound if you turn it more and probably helps to cut through the mix. I’ve recorded one song with this amp and even though it’s technically one channel amp, there’s so many options on it. Very versatile for the studio recordings, you can get almost perfect cleans using low input and edge switch really helps.

Your in-room sonic impressions might be opposite to what the girth control is actually doing in the circuit. The girth pot controls the resistance in the negative feedback loop (NFB), so as you turn up girth, you reduce NFB. With Girth at zero, the NFB reduces power-amp gain by about 10-12dB; with girth at full, the NFB reduces power-amp gain by about 3-4dB. That is why it is louder when girth is turned up (the amp has more of its 'open loop' gain. The amp will be tighter with more NFB (less girth).

Thumbs up for that Porcupine Tree riff!🤘

Monster tone... but that's all I'd expect from thee!

How can i not click on a vid with that title? As i always say - It's not the size of the ship, but the ability for all passengers to get off while in port that matters !!

Damn, that amp sounds awesome. Brutal and unpolished.

My favorite mode of my Mark V is Xtreme- silly name for it btw, the Mark IV and Crunch modes have more gain- but I love it because it removes all the negative feedback from the circuit. It makes the sound louder, sure, but it's a lot more than that. It opens up the midrange, lets it blossom more, and the whole sound just explodes off your pick in a really satisfying way. 'Girth' is a good name for it, lol

I love your playing. It has a lot of joy in it. That’s a great sounding amp. You got it sounding similar to an SLO.

Your guitar posture is always phenomenal. You always look so relaxed. I'm so jelous xD Sometimes i'm like "how does that guitar holds so well without a strap" The amp sounds fearlessly agressive and beautiful.

That amp is awesome! The fact you worked with the builder just makes it extra special....to my untrained ear's, it sounds like you can get pretty much every shape of tone with the girth control....add pedals, and your ready for any gig?

Best Title for a Gear Video on KZfaq EVER!! You fucking did it again!!

Love when you sprinkle in other bands riffs. Took me a minute… love Porcupine Tree

Always wanted to do this if I built an amp, never got there. Great video!

That thing is truly beastly❤

Honestly, I feel Ceriatone should be synonymous with their 2202: it is the amp Marshall refused to build for almost half a century, doubly so considering it is a proper 20W conversion of the 2203 circuit while the 2204 was and is not a proper 50W conversion.

Do you happen to know how the resistor value changes from min to max?

thats a beast of an amp dude ! the negative feedback thing is interesting... i see alot of people do that mod to jvm's. sounds good and changes the tone quite a bit hey. gonna tell my missus im getting a girth mod to be a little more stiff 🤣

That amp's a freakin monster!

Ceariatone amps are amazing. The OTS is great.

Sounds good, but I think your preference is to keep the bass a bit low. I always want to reach into the screen and turn the bass up on the amp settings ha! @7:00 If the bass was turned to about 8-9, middle down to about 4, and gain up to 10, add a Boss SD-1 and NS-2. I bet that would sound sick

Subtle (except for the volume changes) but interesting. But it doesn't really matter with that amp. It cranks wherever you set it.

Hell yeah porcupine tree riffs

Today there is fractal friday in g66 channel i not see in the channel g66?? 😊😊😊thank you leon

Bit of a beast!!!!!!

Girth is where it's at. Just ask my girlfriend. Just sayin

What's the name of the song with the riff at 2:23? I heard it more than once, I'm sure I know it, but can't remember the name 😂

Leon, let’s be honest here: you gonna tell me that Ax Fx or other modeler amps give you the same feeling playing through them as a real amp? Sure, maybe when you’re just running into a DAW with an Ox or whatever attenuator you have, but let’s be real here: Real amp into cabs at a healthy (loud as f***) volume is why we play.

Girth can be to phat when you like lean tones…

🙏🆒️
