NAD! (Finally...)

[misterwhizzy]

After a three month wait, I finally got the Origin 50 head that's been on order to replace a badly damaged one I received in November. It's been here about a week, but I wanted some time to play through it before rendering any kind of judgment.


Classic Marshall look, classic Marshall sound. Dialing in everything at noon was ear-piercingly bright at first, and the gain knob at noon wasn't enough. I think the mid-output level is plenty to keep up with a drummer, and the only difference I notice is a bit less bass thump and a very slight volume drop. It's got that classic rock crunch all by itself, although it does take a bit of volume to get there.


Here's the rig now. The cabinet has a pair of WGS Green Berets, and the Les Paul has a stock Custom paired with an RCA3 59n.

I don't typically think of Marshalls as being pedal platforms, but this one definitely is. The Green Rhino is definitely able to push it into higher gain territory, say Rust In Peace-era Megadeth, and my Klone gives it the "more" of its natural breakup. Adding a Carbon Copy in the effects loop gives it more body. I prefer the pedals as boosts to the built-in gain boost, mainly because they're tweakable. The onboard boost doesn't add much gain except at lower gain levels.

All in all, I love it, and it rocks. Plus, it says "Marshall" on the front.

Awesome. Is it like an import version of a JCM800?

[Open lane]

I have the combo version and love it.

The Origin 50 is a weird one from a marketing standpoint. It is a mix of tube and solid-state circuitry that is reminiscent of some Marshall topologies. Not a JCM-800 circuit, but almost more like the MojoTone 18W TMB with an added FX loop and a boost circuit. I say weird because it has no ( as in ZERO ) circuit relation that you could say was an Origin for Marshall amplifiers. I think that the marketing twist they have is that the price point for this amp will make it the Origin for most beginners and intermediate players to get a real Marshall amplifier.

It is a cool amp for sure, as it does cover a lot of ground with minimal controls. It is made in China, or at least in some other country similar to China, which is what brings the cost down. When they work, they work great, but there is a fair amount of solid-state items in there that when they fail, they fail in a less than helpful way. Psionic Audio has a repair video ( on Your Tube ) that he does on an Origin 20 and explains in some more detail.

Congrats on your new amp and have fun rocking out!

For someone like me, the lack of extra controls is a bonus. I’m not tempted to keep turning knobs. I got a sound I like pretty quickly, and I don’t feel the need to do anything but play the guitar.

There were two main reasons I bought the amp. First was the DSL20HR I had for a day sounded absolutely horrible. Secondly, the Origin is marketed as having Plexi tones at a lower price point and playing very well with pedals. That’s exactly what I hear it doing.

Marshall needed a product like this. Bigger than a lunchbox, with real EL34 tubes. Loud enough to gig. Inexpensive. Pedal platform.

If I was shopping amps, I would get this and use it 4cm. With all the digital extremities, an amp doesn't really need tons of features/channels.

My primary considerations: How good is the FX loop? Can it be biased by end user?

[Top-L]

Also, how much clean headroom does it have?

If you run a clean preamp into the power section, how loud can it get before it starts to distort?

[misterwhizzy]

Yes, it's made in Vietnam, not China. I don't equate country of origin to quality, but I also wouldn't say these are exceptionally well-made.


Exhibit A, your honor, from the head I had replaced. The headshell is some kind of MDF or something, and I think actual solid wood would add a lot of durability and not a lot of cost.

Honestly, not much at all on the lowest wattage mode. I find myself adjusting the vol on my guitar to get clean sounds there.

It's a great amp. I like the sound of my dsl more, overall. All in all, apples and oranges, though. I do like it. Good to have when i want to change things up (i find myself using it on 25watt qnd the room shakes)

[Open lane]

With what i just said, please consider the fact i recently moved a guitar case because it was shaking and rattling in the guitar room. I very well may have interpretting the vibrating sound as a ****ty breakup.

Regardless, i do not like the amp at all in low wattage mode. Sounds good on 25w w/ pedals. That's all i really use it for.

[Ewizard]

The FX loop is simply a solid-state loop. So it is not user-serviceable or adjustable. Sounds fine I am sure. The wattage modes are done by using a voltage regulating circuit that cuts the voltage to the power amp sections B+/HT supply. This is perhaps the best way to reduce volume ( and therefore reduce headroom to induce power tube breakup ), but this type of circuit comes with a downside. The reduction in B+ reduces volume enough, that with typical master volume amplifiers, allows you to hear more of the Pi distortion. Most people are not familiar with the sound of a distorting Pi. It is not inherently bad, but it can be very bright and brittle sounding if larger grid stoppers are not used into its grids. If the whole amp is scaled down ( the power tubes and the preamp section ) it will cause a brittle bright sound as well. Most amps do not scale down both the power amp and preamp, but I am not sure if the Origin does or not? That can be a reason though. My experience with amps like this ( budget-oriented ) is that they are brighter and more sterile sounding than better made and spec'd units.

That all being said, this is still a cool amp and it certainly ticks off a lot of the boxes.

Incorrect. V2 is used as the effects loop buffer.

Incorrect. The voltage to the screens is scaled down in this amplifier. B+ is slightly increased in lower power modes due to the lighter load on the power section.

It sounds like you're making quite a few assumptions based on other amplifiers you assume are in the same category.

I'll leave this for evidence.

[Ewizard]

Certainly wrong about a couple of things. Sometimes I am. The video was hard to watch, a timestamp would have been nice. I didn't catch where he mentions the power scaling and how it was done? Not that it matters much, dropping the screen voltage is still dropping B+, it is just only to that part of the power amp if that is the case. That is the least desirable way to power scale ( dropping only the screen voltage ).

If V2 is for FX loop drive and recovery, then the BOOST is a solid-state driven feature. Doesn't really matter though. He does mention that the amp is fragile and requires care for modifying. Heck, he even had to remove half the components to mod it into a more popular topology. The cold hard facts are that this amp is a budget-minded amplifier, that despite its place of manufacture, weird marketing strategy, and obvious budget-oriented build quality, it is a cool amplifier that fills a need, sounds good enough, and is able to make some good noise. All assumptions aside.

[misterwhizzy]

The more I play this amp, the happier I am with it. I'm finally getting the Marshall tone I've heard on so many albums. It is a bit of a one-trick pony, but that trick has been the backbone of rock acts since the beginning of the genre. Does it clean up perfectly with the volume knob? No, but it's good enough. Is it a modern high-gain monster? Absolutely not. Does it rock? Yes, and hard.

Ewizard, I think the boost is switching out V1b bypass components. I don't think there is any active, solid-state amplification involved.

[GuitarStv]

I want an Origin 20 head. They sound great through greenbacks, and were easy to get good towns out of.
