For 100 bucks this thing is great. It has 3 distortion channels and 3 clean channels and mic channel which i never use because im not sure what its for. It also has 6 effects. I like using the cube mostly for clean as the distortions are kind of harsh to my ears. When i first heard this amp 2 years ago i was blown away with the delay and distortion effects...Today i don't prefer them as much..I mostly like the cleans..Sometimes with a little reverb. The effects are decent but aren't the best. But i still rate it a 5 for the overall score because you don't get this many effects and sounds for 100 bucks. its a bargain and blows away any standard solid state amp
