If you are familiar with the JCM800 sound, this combo will not disappoint. For those who have not yet experienced it, it is definitely a worthy investment. First of all, before I ordered it I was reading blogs and worrying myself about the 10" speaker. I want to make this very clear, the speaker is great! Marshall knew what they were doing, and whatever they did with engineering the box and speaker does not disappoint.
I moved and could not take my 100w Marshall with me and I do not feel like this combo is lacking for my current application.
This things is also VERY loud. It makes sound at low volumes, but it may be a bad investment if you are unable to play at above bedroom levels. Once it's plenty loud, the feel of the guitar in relation to the amp is amazing. The breakup is just right and dialing in a tone is very easy. It's a great purchase for those who may want a portable volume monster as well as those who have never experienced a cranked tube amp.
Great job Marshall!!
Oh, and the fx loop volume drop is only noticable at low volumes, and since you are playing it low enough to notice, this shouldn't be a compliant.
