    Thank you. I appreciate that! It’s a LOT of work and time for sure but still all a labor of love.

    there's a thread on here, w/ a guy who mod's the Ori, & he also includes all pertinent info.

    In that, he rewires the tube order, because the tone stack is not standard Marshall, so he rewires it to other typical order.

    the member here is @burger

    someone else started a thread about his mod:

    https://www.marshallforum.com/threads/if-all-origins-sounded-like-this-wow.118518/

    documented on his website: (schem's/etc.)
    https://headfirstamplification.com/amp-mods

    Maybe that's why it doesn't work w/ the Ori?

    The videos (2) in the thread above detail everything well...

    Thanks! The cathode follower pins are reversed in the Origin - so it’s backwards from traditional Marshall amps for sure. I wish Marshall would be consistent and stay one way - it would make my life a whole lot easier! There seems to be no rhyme or reason for flipping the triodes on V2.

    But beyond that, I need to work with Marshall directly on that series as there are some other factors to consider before stating whether it’s compatible or not. When it is, we’ll add it to the compatibility list and page.

    I just did a quick review of the video.

    On the Ori series, V2 is used for the tonestack & tube buffered effects loop. In that mod, he removes the loop altogether & moves the tonestack until after V2...

    Based on this, none of my designs will work in this Origin model circuit. So that answers that. Thanks for sharing the info.

    No worries man. Pedals in front on this amp do. Some in a real big way.

    Easy for me to say when I have the Lynch Mod already in my 800...:eddie::D

    For now I'm staying out of the inside circuit mods although that shit sounded good to me. I got ripper amps already but what I really dig about this amp into its preamp/power section is old school fun. And that's my era talking. Really using it as a blues, rock and hard rock blast from the past.

    I'm finding its rawness and thump set right really puts a smile on my face. Would love to take it to a blues/rock club. The good ones let you go loud. To a point.

    I will admit the Ori has its own Marshall voice.

    I hear you...

    I wouldn't mind just changing that part of the circuit, w/o the booster up front.

    I got a real nice 12AY7 I put in V1. Not a bad thing happened and if you want Plexi articulation that still crunches and a bit more? I'm still shocked. Just got it today so I've been putting it through classic to hard rock joy. It works. Articulate bottom. Add it with my Breakdown pedal on stage 2? Into a 5153 EVH cab? Trying to be careful. Not over hype. Gear chains are diff so is taste. At its simplest? I can't get enough tonight.

    Tomorrow? It may sound like shit! You know how it is bud. :lol:

    Well I've had mine long enough not to play footsies with sensibilities. Comes a time especially when you're running a Marshall that a certain piece of gear comes along and wakes your ass up!

    I make no apologies. Plug and play? Simple.

    Got my Hot mod v2 evo this weekend, installed and fired her up. Thing kicks serious ass! I was eventually going to mod my amp and now I don't have to. This thing is super quiet too. Quickly ran it through it's paces. I like the bass switch (down) for the tight mod setting and the gain in either position but (UP) for leads. The only thing that sucks with the studio versions is the component layout compared to the bigger brothers for accessibility but that's not on legendary tones. Super impressed with this unit, totally worth the investment for the price and then some especially compared to a boutique dirt pedal! Took less than 5 minutes to install.

    Thanks for sharing! The Hot Mod V2 Evo has been getting a lot of interest I think not only because of the flexibility adding the bass switch, but the $199 price point is also less than the original Hot Mod V2 used to sell for. The Evo is now built using a thick double sided PCB (with through hole components), so labor time/$$ is reduced vs the handwired versions (Lynch Mod will remain handwired). Still built by humans in the US as well :)

    Just ordered the new V2 based on how awesome the first version is. Should be fun to do a side by side of the two.

    I would like to order, but a couple quick questions. I am definatelly a high gain guy, which would be better for my 1959hw? Would that unit work in my SV20 head as well? I am a big fan of BASS cuts, but I do use a horizon devices precision drive which has a sweepable HPF that takes care of cutting bass when needed.

    I have the headfirst mod done on my Ori 2 so the v2 will work? I have the metro loop I still need to install to.

    you'd have to ask Dave...

    I'm not sure how standard V2 is, now in the Ori, after HF mod. Still could be wired backward, if it's set up so that it'll work.
