All user reviews of 2/5 for the Marshall JMD501

Hybrid digital modeling preamp and power amp tube (12AX7 EL34 +). I tried the combo version 50W.
The connection appears to be complete with an effects loop in addition to the integrated effects section.
I put a 7 because it's good, it could have been better -- with two volumes as an example -- and motorized knobs as the Spin Doctor T-Rex.

UTILIZATION

The setup is fairly simple. I have not read the manual, but the basic settings are fairly intuitive. Actually, for each preset, you end up with a basic amplifier and its settings,  gain, tone-stack volume. Then-delay modulation effects, reverb, and the presence and master.
In terms of getting good sound easy, I still say no, because it is not obvious to find the right preset, the best clean / crunch that I found was in the overdrive section ....
Then, the rotary knob that lets you choose the type of preamp is not super readable, we do not know exactly where you are, battery-haired, above or below ... So in the end it by ear ...
Therefore not easy to find the type of preamp, then I do not find the grain and responsiveness that I was looking for. I tried this amp in order to replace a JVM410 a bit noisy, which I am obliged to insert a noise gate and effects in the loop, the JMD seemed to be the solution all embedded ... Verdict: we are very far from the goal ...

I put a 4 (inadequate) because here in dire need of clarity, we do not know what preamp is used on any patch, and we do not see the settings directly. Difficult to get consistent sound. The preamps are not necessarily listed in order of the gain level for example ... short, not super intuitive, in the end we do not know where we are and where we go. In this case it is difficult to find what we seek, the more difficult for discerning guitarists wanting a good sound out of this amp, it will be virtually impossible given what it can offer ...

SOUNDS

Then the sounds: the biggest weakness and it is indeed a pity on an amp in this price range. as mentioned I wanted to write another attempt on numerical modeling after reading some positive reviews in the jungle of opinions (which are mostly negative on this amp). So I wanted to make my idea ... Verdict:
- Clean sounds are quite beautiful, but lack of dynamics, it says I'm not too pushed the volume, therefore possible that HP has not had the desired response. The various configurations of pickups on my guitar (double, single, round, bridge, center, mix, etc.) did not yield large differences in rendering, it's pretty deplorable.
- Sounds crunch have no interest, severe lack of gain.
- The overdrive is most interesting, there is a little full range of sounds, from clean to crunch pushed, but still this lack of respect and not dynamic microphones.
- The leads ...
Well, I'm not at all impressed by this amp. On the other hand one could say that I compare to a JVM ... but I also have a MG50FX (new in 2009 then), and honestly, there is no picture from a MG50FX JMD501 and what that costs 3x the price, MG50FX is well ahead in terms of grain, reactivity game and the guitar volume and the various configurations of microphones.
I liked almost nothing about this amp, only the FX section is doing compared to others, they are digital effects, here is doing his job properly neither more nor less.
A choice, better take a MG50FX MG100FX or it will be less fragile and far better in sound reproduction.
I put a 3 (poor): my opinion unless severe hearing loss or stroke of luck monumental, impossible to make anything of great (except maybe clean)

OVERALL OPINION

The test lasted about 30 minutes or 1 hour is not much, but I am not extended, I could not find a grain that suits me and can serve as a good basis to work. I am not too bent on equating the sudden, I look first and foremost an amp that responds correctly for the attack and guitar volume, there is nothing all that.
The only positive is that it incorporates a section of the effects sufficient to live.
The downside: almost no sound exploitable in an amp supposed to emulate the 16 best productions of Marshall over the past 40 years ...

Finally, an amp that costs the price of an amp lamps very good but that does nothing more than low-end modeling ...

I have owned a lot of amps, I do not remember having been as bad. Note that I play on Marshall JVM and MG at the time of writing this review and I am absolutely delighted with these two amps. The digital is progressing but is still far off.
Just listen to the demo site marshall, we say that this good chris george has not made a big effort on the settings, the sound is a bit tinny and flat ... ben in fact the contrary, it is wonderfully sound this amp, this guy is a god ... wow ... Finally, when comparing it with other amps out of the brand you get better at locating the JMD ...

I put here a 3 (poor), which is my overall feeling on this amp. After the test I just told the store clerk: "They were wolves that blow at Marshall, it is far from that offered by my JVM. Vendor response: "you compare a race car and a 2cv" ... Reply: "the price of a 2cv race car ... that sounds worse than my MG50FX" ... answer: "it's true ...."

Now everyone does as he pleases, and as he sees fit. It's my feeling, I tried to translate it, some will find to their liking and in fact: it is essential.
