I picked up one of these because I needed something tiny to haul to lessons that would give me some real tube crunch and grind at a volume suitable for giving lessons at a music store. For that purpose, this thing delivers!
Here's a soundclip of it, both pickups on my SG Bass straight into the amp. Wattage set to 1/10th of a watt, which is much louder than you'd expect, volume fairly low, just enough for some dirt, and tone somewhere fairly low. Check it out:

The other thing I want to get out of this amp is a gnarly distorted slide bass tone, to inspire me to work on my slide playing. Maybe I'll do a soundclip of that sometime if I get a chance.
