First of all i have to say a big thanks to Thomann employs for the fast delivery the safe package and the perfect Greek customer service,I was a little skeptical for something so expensive and fragile...... but the anxiety was just a waste of time.
The building quality of the head is perfect, outside/inside everything is very carefully made ! Just a beauty !
The tone character is exactly like the big Marshall , sweet "Marshall" cleans and the absolute crunch with unlimited clarity even at full blast ..........but the wattage difference between the original and that model changes the overall fullness feeling.... and the KICK to your back from the moving air .
If you play on small/medium gigs the MKII studio is perfect , the big one needs attenuator (I don't like attenuators). But don't be fooled this amp is LOUD , on << 5w >> shakes the wall of 5th floor and I living at 2nd.
Takes pedals like a dream... tried with wah , fuzz ,drives, booster....
I don't like effects loop in general but i have to admire the way that takes a big delays and reverb on full volume.
The 5w mode is pretty good ,less bass , less open sound ,more compression but very enjoyable for home or small party
I have nothing to complaining about. I am very impressed with that 20 watt amp after all that toys from Marshall the latest years.sound/tone ,features ,power, ... everything perfect! now the only that remains is to show how good this amp is on the road .
