I haven't tried this but it could work very well. My only concern is the bass frequency for the kick drum and the floor tom. The blurb mentions every instrument except bass, which could mean that the low frequencies are not particularly well handled. Laney is a good company and so do a sound check and listen for the bass frequencies!
I'm a bassist and a drummer so I use modern bass amps, which have plenty of top end as well as lashings of bass.
Cheers
