I got this amp as my first real tube head; and it is perfect. Screaming high-gain, beautifully defined crunch, and shimmering cleans, all in one channel.The shape control is quite versatile, and can get many usable sounds.
The Orange Dark Terror is a lunchbox amp, but it's a lunch that is a full rack of beef ribs, fries, baked beans, and a lovely stout. It's LOUD, it's got that nice Orange tone, and it's actually very versatile. Although it's only got three knobs, it cleans up very well and delivers the #gainz when cranked up. Even at 7W this amp is very powerful. One thing to note (for people who haven't played through it yet) is that the higher you put the gain, the more of the Orange "fizz" you will get, whereas the volume will just make things louder. The shape control is actually very useful and can take you from 60s tones to modern metal. Get this amp.
