A tube amp of a solid state amp. It doesn't seem like it, but this amp is veratile.

This amp has a stunning, shimmering and responsive clean tone. The distortion and reverb make it surprisingly versatile even when the EQ knobs are not very sensitive, (except for the bass, I feel this amp has a TON of bass). When the distortion is engaged you get a very classic tube like overdrive that is very distinct and unique, very fat and sort of bright. My personal favorite thing to do with this amp is too use a boost pedal (amp boost off) with the distortion on 10. It give a biting, cutting, but very fat and wide sounding distortion when the treble is high. I love this amp, they are relatively light and very durable, it just inspires me hugely! it can be used for doom, thrash, alternative, pop, and I think this amp would especially good for surf, even though I've never legitimately played surf on it, I can tell that the giant sounding spring reverb, brite and clear sound in it would be perfect for surf. It is also very easy to use and dose not require much tedious tweaking. If you can, Go buy one!
