I got a Dark Terror amp about a month ago. I was looking for something small (no more than 20W) to play at home (primarily) and the band practices. I was considering many options, incl. Orange, Mesa, Blackstar, Marshall. I needed an amp to be able to do old school Bay Area thrash (think Metallica, Slayer) and finally decided to just dive in and got the Dark Terror. And boy, does this amp deliver. It packs a good set of features: 100% tube single channel with 12ax7 preamp and a duet of EL84 in the power amp section. Two power modes: 15 and 7 watts, volume, gain and shape control, which control the amount of mid frequencies you have in the sound as well as some highs. For example, turning the shape know all the way clockwise scoops out the mids while brings lows and highs up. It also delivers an insane amount of gain, way more than the original Tiny Terror has and I use gain at about 2 o'clock for thrash (straight to the amp, no boost, no tubescreamer, etc) at which setting it is nice and tight. Also, unlike the Tiny Terror, it offers a tube driven effects loop to connect your time and mod effects. Despite being a single channel hi-gain amp, it cleans up quite nicely, especially if you can work your guitar volume knob and split the humbuckers. At first I wished this amp had a full 3 band eq, but the shape control works quite nicely and I plugged my eq pedal in the loop but have taken it out since. The amp is pretty loud too, but even at low volumes (volume at about 8 o'clock) it sound really really good. Some of the youtube videos make this amp sound really fizzy, and it can sound like that if you dime the gain. But at that moment the gain is just crushing and I personally don't see myself ever needing that much gain. I have not tried it with other styles of music, as my primary focus right now is old school thrash, but this amp is just meant for that kind of music.
