I bought this on to have a decent sound when I catch some time to play when I am home... I did not expect much, I mean, solid state 15W amp, come on... But, I was really surprised when the sound came out. I tried it on USA Fender strat and they get along quite well. Single coil pick up sounds great on the bridge position. Reverb is ok, not much but it does the trick! Clean sound is quite good, not Fender clean and good, but maybe it is just my subjectivity (I have Fender hot rod deluxe, so mind the bias).
The best feature is aux for smart phone etc. I thought, this feature is just another line on the list of specs and it cannot sound any good... I tried it out, just for the sake of curiosity... I was overwhelmed! It sounds great! You plug in your smartphone, find some decent backing track on youtube, and you are out of excuses! Yes you can jam all you want and feel as if part of the song in background. My wife, could not believe I was playing along, until I stopped playing and she realized, the guitar part is missing! :)
Gain channel is really versatile, it goes from bluesy rock to decent metal sound (like any Marshall should)
I do not like the change in power button and channel switch button, it feels really cheap and I do not know how much money Marshall saved on these two. I liked those robust buttons more (you know what I am thinking...)
The overall quality is ok, I would like to say good, but not quite there... I guess the target price had to be reduced somewhere.
All in all, do buy this amp for home practice and jamming, I am sure you will not regret. After all it is Marshall and will be sold more easily if you want something bigger, louder, keep that in mind as well.
