Re-Review of the JCA50H
« on: November 13, 2013, 04:22:49 PM »
Cheers guys,

so some of you may already know that I got myself a new amp not too long ago and now after having had some time to toy around with it I give you a revisited review of it.

Now first of all I have to say again that this was a steal regarding the price of 300 bucks I paid for an all valve amp. Sure there are better heads out there but if you're in a situation similar to mine, namely being a poor student, this is a great bang for the buck.
I feel that the "made in china" label has lost some of it's bad reputation, Mike Soldanos role in the design of the Jet City Amplifiers may have contributed a great deal to this.

Anyway, after initially being dissatisfied with certain characteristics of the amp I borrowed my mates ENGL 4*12 cab with broken in Celestion Vintage 30s to see how much difference it would make compared to my Laney 4*12 with Celestion Seventy 80s. In short: the change in sound is huge. Not only do the V30s take away a lot of the harshness in the high end (yeah I know that shouldn't be the case usually) but they made my Valveking 100 sound better as well after the tube change it went through.

Just to clarify: I'm sure the Seventy 80s can be great speakers when played with darker amps and their clean sound isn't bad either. They just have a weird frequency response and when you have a bright rig like I do it can get over the top pretty easily as they seem to be enhancing the high end. When I have the money and the time I'll swap em out for either Vintage 30s or Eminence V128s so I'll have a combination that fits my Valveking.

Anyway, back to the Jet City:

I'll try to keep this short, going from clean to distorted.

Being a cheaper version of the Hot Rod 50+ it surely doesn't sound as well as it's USA made counterpart, but it's based on the same idea. As most people know Soldano isn't famous for his amps clean sound, but it's more than usable, especially when you consider the fact that it's meant to be rather a crunch channel anyway. Keeping the preamp low and the master volume high you get a nice spanky clean sound that reacts great to your picking, I usually play the middle position on my Dinky through it, the combination of the Painkiller in the Bridge and the Coldsweat in the Neck. With my Strat I can get great funky and bluesy sounds when I combine the Middle and Neck Slowhands and being the straight Clean/Distortion two channel amp guy I find it good to add clean passages in metal songs. Throw in a Delay and a bit of Reverb and you can do that spherical sounds pretty well. As said it's not a Fenderish pristine clean but I'm sure people won't buy a Jet City for stuff like that anyway. Good enough for me!

Turning the gain on the crunch channel up gets you into blues/rock/hard rock territory very fast. Depending on the amount of preamp saturation and the boost from a TS type pedal you can vary between Hendrix, Gary Moore, AC/DC and Guns n' Roses just to name a few. As mentioned earlier the head is very touch sensitive and uncompressed giving you all the possibilities of altering it's sound with your hands. In combination with BKPs you get very clear note separation and harmonic richness. Although I use my Micro Terror mainly for blues and rock it doesn't hurt to know that the JC50H can do this stuff as well. If it had only a tad more gain on the crunch channel you could even use it for Thrash Rhythm in combination with a boost. But you have the lead channel anyway, so no need for that  :P

The lead channel. Now this is where things get interesting.
I have to repeat myself here and point out that this amp is uncompressed, very touch sensitive and UNFORGIVING. If you're used to 5150s, this will shock you and hit you in the face once you realize that your technique is too sloppy to keep up with the JCs accuracy. Now I'm usually a very tight rhythm player, but everytime I would just lightly touch an adjacent string that isn't meant to be touched I would hear it. This is especially the case when you turn the volume up.
However I see this as a good thing because once you adjusted your playing to it you get rewarded with a detailed and precise sound that hits you in the face and stays clear and defined at all times. I even turned the preamp gain down from 7 to 5 and still had more than enough distortion.
A Tubescreamer or Boost in front is a must as the low end is huge but too flubby on it's own, but other than that everything is fine. Notes fade into harmonic feedback easily and the sound cuts very well.


The only negative thing that is still present, but tamed a great deal by the ENGL cab, is the fizziness. The problem gets worse on lower volumes, the louder you turn your master up the less you hear of it.

However I'm planning to do a complete tube swap and re-bias it as Jet Citys come usually biased very cold from the factory. I'll be throwing in JJs in the preamp and power amp that I'll be getting from Eurotubes and then experiment with different valves in V1 and V2. The Jet City 24s cab is on it's way as well and I'll order some new speakers like mentioned before.


So in conclusion: right now everything is fine stock and not disturbing or lacking to the point where I can't live with it. Sure I'll do plenty of finetuning, but for the money you pay you get a very decent piece of equipment. Maybe this review helps someone somewhere. Pics are attached.


Cheers!

Yep, Sounds like Soldano DNA. Although i don't find them fizzy. Saying that, i reckon its partly due to the lower volume, those tubes heat up, it opens up.

I guess there's a depth control on there? In my estimation the HR50+ (and most related Soldanos) tend to be tight and thick rather than warm and fat in the bottom end, very snappy, so am suprised to hear the low end is flabby.

I see you're also discovering the range of sounds that can be had from one. Not bad for a 2 channel amp with a shared eq ;)

Finally yep.. in the case of Soldanos they're one of the few amps that force you to become a better player, because if you bum note it, or have poor technique, everyone's gonna hear it lol

Glad you like it.

Nice review :)

Yeah if you ask me the jet cities are killer deals. You can get a pro-sounding high gain rig (when combined with the harley benton v30 2x12 cabinet) for ~£400. Which is awesome.

As a very tight rhythm player I want one to see if I'm as tight as I think I am

Actually I want a guitar battle with you to see who is tighter :P

I would loose that battle anyway, so I don't bother.  :D
Nice review btw. Certainly a nice affordable amp, but I guess not for me. I like tweed- and plexi-tones.

I highly recommend v30's for the 20w version as well
makes all the difference
it sounds muddy and fizzy with laney stock speakers and with most other cheap ones, but gets a lot thicker and clearer with v30's
the downside of high gain small heads with el84's is that they usually have a very narrow volume range to get a tone that actually deliver a greatig b tone comparable to 50 watts amps
most people think they'll have cranked big amp tones from 15w-20w amps at home, but they usually only sound truly good with master at 4-5, and that's loud as $%&#
anything below sounds fizzy and things get too mushy after passing half the volume

from everything I heard in the last 3 years, I wouldn't expect the jca50h be any less impressive soundwise than anything in the market
it DOES sound like a Soldano, although an A/B comparison would obviously sound different
and I'd pick a JCA50H over a Soldano SL60 any day

So I did an AB comparison the other day between my Valveking, the Jet City, the Laney and the Engl 4*12.

Guitar went into my Digitech Bad Monkey which has two outputs, one for the amp and one for the mixer, which is a very handy thing.

For the first time in my life I played two amps at once, the stereo type wall of sound you get is an amazing experience, and damn it's loud!  :lol:

Anyway, the conclusion is: the Laney Cab, or rather the Seventy Eighties really do suck.

Both the Peavey and the Jet City sound waaaaay better with the Engl, the Laney just has a very boxy and scratchy sound with no balls, it makes your amp sound shrill and small.

Right now I'm not even sure if it wouldn't be just better to get a proper new cab rather then switching out the speakers, but I need to get finances sorted first.

Anyway, doing a direct comparison between the two amps I noticed the following things:

The Peavey has a lot more compression and tightness going on, the sound is more on the modern side of things and is way more forgiving. Whilst this may be a good thing when playing on your own you could drown very easily in a band mix if you don't go easy on the gain.

The Jet City is very open and more eighties in sound, less tight and needs a boost at all times when you go death or technical metal. At the same time it cuts like a mofo and almost drowned the Peavey, I had to turn the Valveking up way more to compensate for that. So if you don't have quite some chops and can't dig in easily it won't please you.

Played together the two of them achieve quite a nice mix, one filling out the frequencies the other doesn't. In conclusion I have two cheap amps right now which can do quite more than people give them credit for.

Anyway, I still have a lot planned, switching out tubes, re-biasing, getting the right cab and so on  :)

Cheers

If the Valveking is anything at all like my 6534+ it doesn't like having the gain wound up too far.  It works much better to have the gain lower (e.g. 4 or 5) and add a tube screamer as a boost.

That said at gigging volumes my amp cuts through like crazy, even with no pedals at all and the gain up quite high. It's the presence control that seems to affect the cut most.  The VK and the 6534+ are different beasts though.

No surprises on the Laney cab.  They are cheap second-hand here for that reason.  Particle board and horrible speakers.  Only their top-end stuff is good in terms of speaker cabs

Yeah we told you 70/80s weren't great :lol:

Way I see it, good speakers won't make a bad amp good, but bad speakers can make a good amp appear bad. I personally wouldn't judge an amp if I knew I'd only got to try it with mediocre (or worse) speakers. Admittedly speakers are hard to get to try so that's not always the fault of the prospective buyer... i've tried a bunch of things which I've probably unfairly written off which may have been great through better/more suitable speakers :lol:

It's a judgement call regarding getting new speakers or just biting the bullet and getting a whole new cab. It basically boils down to the difference in price, the quality/suitability of your current cabinet and which specific speakers you want. If you want ubiquitous speakers like v30s or similar it may well be cheaper to just get a whole new cab and sell your current one.

If I get the money I'll be buying a Zilla Superfatboy, but it's more probably gonna be the Jet City 24S :P

or just get an orange cab, which come loaded with celestion V30s as stock
