This is the 50 watt combo version of the JMD:1 amp. You get the same great features and tone. However, the tone will be a bit more spongy due to the cut of half the wattage. You will get a bit less headroom in the overall tone.

This amp is an interesting take on the new wave of amplifiers. They take the digital side of modeling and combine that with the power tube section of your already familiar Marshall tone. It was a big surprise at how close to the amp models that this amp comes close too.

So basically it is a digital preamp and a tube driven power section. The preamps cover just about ever Marshall amp that they have done and it does a surprisingly good job. I have never been a fan of amp modeling as most of my experience has been with Line 6 and those things sound terrible. So when I first heard this amp, my ears immediately perked up.

The amp covers a lot of Marshall ground and the price is nice as well. If you can't find a decent tone out of 16 amp models then this isn't the amp for you. So you should be able to quickly get the sound you are looking for in about 2 minutes or less.


At new these amp come in at around $999, which isn't a bad price for the features and tone that you get. There are plenty of hot-rodded Marshall tones available in this amp and it doesn't take too long to find them either.

I would recommend this amp to anyone who loves the Marshall tone and can't decide which series they would like to have. The tone come as close as you can get for a modeler and sounds fairly organic.
