It's a very cool idea, and I think the second volume stage makes it a good value.
But...I had a Micro Terror and I could not get a decent sound out of the thing
at anything less than gigging volume, which to me kind of defeated the purpose
of having a tiny amp. At home/practice volume it was sterile and lifeless
and that single tone control didn't offer enough range.
Maybe I just expected too much from $150 amp the size of camera.
Wow, I totally loved the tones of my Micro Terror, and very rarely ever cranked it
much more than half. It would rattle the windows in my house if I did.
I thought mine sounded best powering a hand made 8 ohm cab with
1/10 and 1/12" speaker. I called that the
"tall rig."
But we all have different styles. I always played mine with my pedal board
in front of it. Tuner, EQ, Blues Driver, reverb. Getting great tones was easy
with my pedals in play. The amp never sounded sterile with me.
If if did, I'd tweak the lower mids on the EQ pedal, without fuss. *shrugs
Below is what I called the "short rig" with 1/10 and 1/8" speakers. This
sounded great at low volumes. I got my distortion from my blues driver, and didn't
need to bust my eardrums overdriving anything.

So I liked mine for its light weight and tiny size. I fostered it with friends
because I decided to take only one guitar amp when I moved, and settled on
my Vox VT-30 because it does everything I need.
A hard choice, but I made it. Now my friends get to enjoy this.
Now that I'm settled in, I feel the G.A.S. bubbling again.
But I'm not buying anything right now.
Just looking, thanks...
