I know what you're thinking...
5 Watts? C'mon.
Lemme tell ya: If you playing in your apartment, and you "go to eleven" at the full 5W on this thing, it won't be long before somebody calls the cops.
If you use the button on the back to turn it down to 1W, and you "go to eleven", after a few days, you're girlfriend will begin planning the break up.
Can you gig with it?
If you're in a Judas Priest cover band, and just like destroying a room, go ahead; stick with your 50watter.
Now, I'm sure there are face-melting guys out there who'll challenge me on this, but for small joints, yes, you can absolutely gig with it. You can definitely play over the drummer. It's not obnoxiously loud, and audiences who want to HEAR good music AND still be able to socialize will be huge fans.
If the room is more than 50-80 people, or larger than 1000SqFt, you'll certainly want to mic it up to a PA, but it'll give you great sound.
If you're playing at home, at small bars, or especially if you're recording with it, and you want that unmistakable Marshall growl, there's no better amp out there for the money.
I tested it against the Fender Bassbreaker 007, and it wasn't even close. On the other hand, if you live in the single-coil Fender world, you'll probably prefer the 007, but for Gibson Humbucker rigs, again, it's not even close
I absolutely love this amp.
...you need to do what I'm CERTAIN that Marshall WANTED to do, but just couldn't, because they wanted to keep it at it's (excellent) price point -- upgrade the speaker.
The stock Celestion Ten-30 works well enough, but I swapped it out for a G10 Greenback, and now, it's just jaw-dropping.
The DSL 40 is $200 more, and that's a great amp too, but in terms of tone, the DSL5 with a Greenback edges out the stock Seventy-80 in the DSL40.
To sum it all up: WITH the Greenback, this is MUCH more than a "bedroom amp". Excellent for small venues, excellent for recording, will sound great on stage when mic-ed up to a PA. Every Gibson guy will be glad they got it.
