Just to be clear - in my case, this amp is used as bedroom practicing amp. Tested with both singlecoils (Fender Vintage '52 Telecaster and Stratocaster with noiseless pickups) and humbuckers (Duesenberg Starplayer Special).
First notable thing - compared to limited 1W edition it's slightly smaller, which is understandable considering it's 8" vs 10". As much as I can see myself (and also stated in official Marshall documentation) it's having 3 valves in total, not 5 as stated in product description.
Sound is actually way better then I expected it. It's not 'boxy' as I thought it's going to be (having 12" external speaker as well) and there's definitely not same level of headroom compared to something bigger than 8", but that's also to be expected.
On clean channel, you can turn it up to max and still enjoy playing inside your bedroom. 0.1W is of course welcome in case you are using humbuckers at midnight, but even in that case it's very acceptable for my taste. If you are telecaster fan then you are really going to enjoy clean channel with it. That's 'the' sound as I imagine it when I think about telecaster.
On OD channel, you can play a lot with both gain and volume. 1W there can be little bit loud, specially with humbuckers, but I think 'the issue' here is just perceived loudness since I was still able to talk over it, specially if you are not really sitting on it.
Footswitch is quite simple, it's letting you only to change the channel, not to turn on/off reverb or fx loop as advertised on other models, so don't be confused on this.
All in all, this looks and sounds really cool, and I'm quite sure I'm going to keep it.
