I used this amp as a monitor for my Yamaha DTX700 edrums, all I can say is - fantastic..
The drum bass sound is so full and loud, you will never hear any picking sounds or clipping even at full volume.
The only downside is that its quite heavy, and the cable connections are located at the back, but thats minor.
The best part is it has a built in equalizer, so you can shape the sound very easily.
I would probably recommend this amp to my friend...
