It's my first Marshall amp and I don't regret buying it. It only has three valves in it, but it delivers 5 glorious watts of beautiful harmonic distortions as I imagined it would. Power chords simply sound delicious :). It is built like a tank, the emulated output is acceptable when you don't want to use its speaker (you'll have to disconnect the speaker before turning the amp on in order to use just the emulated output, otherwise both the emulated output and the speaker will work in simultaneously, as I understand there is an internal load that is engaged when you disconnect the speaker). I think the 5 watts are more than acceptable for my current use in my apartment, I usually keep it on 1 watt power the volume pot somewhere between 3 and 5... no, it does not go to 11. I don't think the amp would manage to be heard in a club gig without putting a mic on it, if that's your objective then go with the 20 watts version.
The only drawback I see, is that at some point I'll have to replace the power valve and I wasn't able to find documentation on how to check and fine-tune the bias of the output valve, but I guess I am supposed to go to a dealer or tech to do this job... right :). We'll see that when that time will come.
