My opinion is on the JTM 310, EST to say the version with 2 HP 10 '

So we have a wonderful combo zici a very compact size, full lights (3 of prampli, 2 power) for a total of 30W. 2 channels, clean one that has the characteristic of fast super cruncher (yeah!) and a saturated are the opinions are quite controversial. I will come back.
Thank you Jim for having put a DI output connected to the preamp, and an outlet for a cab. an effects loop is also very useful. as an input for the footswitch and I think we went around.
Good afternoon, routine, an equalizer, reverb, we are happy to have a master volume (for beginners, it allows to saturate the preamp lamps without screaming beast).
I would have had a headphone jack, but a full 30W lamps that would have been difficult to conceive.
Purists will say that the lack of an equalizer and a separate reverb for channel 2 ... So in terms of features, it deserves a 9. Why not 10? because on one hand the original lamps (China) are not up, and it is blowing to have to change lamps when you buy an amp nine, although Desomer, we find that the market of opportunity, therefore, almost all are Retube. On the other hand, it is heavy, and it's really annoying to carry, especially since it is the carcass weight is 80%.

UTILIZATION

The configuration is simple hyper. I do not take my head, I have used. anyway, a good amp, it feels right now, even when it is not resolved, it rings. is the case with this one. The sound is good right now, the sine qua non is that we can push a little machine. And yes, it's a tube amp, it is expressed only if it is pushed. Not ideal in my opinion the game apart, though it is possible, but in these conditions it will not benefit from the dynamics of the lamps and the wonderful crunch.
Boosted channel ... objectively say, if we can get something clear at low volume, channel saturation is poor under the same conditions. even with lamps top wig, there was a nasal sound, worthy of a bad amp transition. on the other hand, turn the volume up, it's still something else.
Marshall purists will tell you that this amp does not issue the Marshall's ... They are right. Others will tell you that the saturated sucks ... They are wrong. If the resulting sound is not really that of a JTM 45 or a JCM 800, it's just different, and it must be said, far from the taste of everyone.

SOUNDS

My style of music ... in fact I have not too, but whatever my delirium, the receiver follows me. Its limits, it will be the big trash metal (I do not play, the better: D) and, as silly as it sounds, clean sounds at high volume. This amp crunch so fast it is difficult to get clear sound when playing in groups. It's a shame, but hey, it's only 30W, so you can not have it all.
I use a strat US, and my favorite channel is the clear, with the volume (preamp) thoroughly, and the master of 8 or so. I do not use any of the other channel. The crunch is fabulous, the sounds are crying with happiness. I like to spend all my pedals and just play "like that". Otherwise, with a slight chorus with the crunch, yum: o).
I said that I put the lamps for the Elite and Svetlana preamp to the power (the EL34 orginelles were replaced by 6L6): delectable. I have not had a chance to try it with good humbuckers or P90. We remain in the minds of the bluesy vintage amp, the result can not be inherently bad.

The only concern of 2x10, it is that scalability is limited. In return, we would obtain a better definition sounds clear.

OVERALL OPINION

I use it for several months, at home and again with friends. There's no wiggle in it need an amp whip, low volume, except for clear, dynamic enough, we feel that it is not made for that. The feature that attracted me the most is its ability to quickly cruncher, I never tire of the sound that emerges.
I had fun comparing it with my Hughes & Kettner combo acien to transistors, the difference is impressive in terms of dynamics.
On occasion it is not too expensive for (- € 400) and has such a bad reputation because of its saturated channel that nobody wants: D great to buy!
So I think just for that one day I amused myself by buying another into a head (just transfer the HP and resize the box) and I connect it to a cab. I think the potential is enormous.

In conclusion, a clear sounding amp crunch wonderful, and saturated sound different from the standard brand. My philosophy is that it is better to buy an amp for his clean sound for his saturated sound, since one can always put a distortion pedal to get the sound you want. While a clear sound pedal, I never found

He deserves a 9 / 10 easily, I take a point because of its clear unobtainable volume medium / high.
