Yes, the sound quality is plenty good for recordings.
Here's the thing. You need to understand that the physics of speakers vs a recording is very different. What I mean is this. "Your tone" that sounds like the left hand of Gawd on a 20 foot Steinway through your speakers may need to be tweaked for recording. The WA has a powerful EQ section so that shouldn't be an issue.
I run a 15" Scout combo. I had great results a couple of times recording for a church using three channels. One DI clean box straight into the board right offor of my P bass. One DI from the Walkabout. One mic (and I don't recall which mic) about three feet in front of the cab with a blanket draped over the combo going over to a chair right behind the mic (pretty much creating a very dry blanket tunnel).
We ended up using mostly the Walkabout DI for most songs. However, a couple of times we blended in more of one of the other tracks to help it fit the mood/mix of the song. So, if you have the tracks available, give that a shot.
