If anyone is in the market for a small tube combo under £500, I'm certain you couldn't do better than the Tiny Terror.
With the 7 or 15 watt options, it's perfect for recording, or smaller sized venue gigs, and the sounds you can get out of it are just about the most authentic, organic things you'll ever hear from a small tube combo.
The first thing you notice, well, at least the first thing I did, is the overdrive, which is simply some of the best crunchy, dirty tube breakup I've ever heard. But, with only three controls, Volume, Tone and Gain, it's easy to modify to your own wicked ends, and although finding a really good clean tone is admittedly harder than finding that perfect crunchy overdrive, once you find it, it's as clear and beautiful as any Fender amp I've played.
Another impressive feature is it's versatility, aside from maybe Jazz, I'm certain you could use this amp for anything and sound as good as any amp that is designed specifically for the genre.
Also, just look at it. It's orange!
So, yeah, if you're looking for a small, but loud, tube combo, I can't recommend the Tiny Terror highly enough.
