This amp was my second choice after Ampeg. The Ampeg I wanted was quite spendy, so I chose this one. I would probably buy the head if this amp was ever stolen. Why? It has 2 speaker outputs, this one only has one. Which Hartke should've done in the first place. I do like to roll it out and take it with me to practice, the only thing I don't like is the weight. It's nice that everything is right there, all you need to do is plug in. No worrying about cables or anything, it's all included.
Features: If you have the cash, buy this amp. It's a pretty simple combo amp, it's pretty loud. The thing I like about it the graphic EQ, and the compressor switch. It's been louder than my guitarist's amp when we jam, overall it's a good buy. The only thing I didn't like was not being able to add another cabinet to it. It's only got one speaker output on it. It's a good buy, it'll last until I want something louder.
Sound: The sound quality on it is great, deep bass and nice highs. Sometimes it sounds to high, so I just cut back on the highs. I usually run it straight with no effects because it sounds great without effects. I used an effects pedal on it and it just killed the sound. I assume that's because the pedal was a crappy pedal. Like I said, it sounds great loud and doesn't distort.
Durability: It's very durable, which is always a good thing. Don't get me wrong, I'm not saying to throw stuff at it and see how it holds up. If you drop it hard enough, it's gonna break. But if you bump from time to time against walls, it'll hold up. And I don't like the carpeting covering on it, it starts to fray out. I think it would've been better if they used like a vinyl covering on it or something. As for being retubed, I haven't had retubed yet.
