I bought a Shuttle 3.0T with the 1x10 extension cab. (300 watts SS)
This amp and cab was very well made.
Light weight, a breeze to move.
I used the amp at home for a few weeks at low volume.
It sounded great by itself.
Took it to it's first gig last night.
To my surprise it sounded bad in a group setting.
It was a medium volume gig. (Bass, drums, guitar harmonica)
It lacked presence, sounded weak, no bottom.
It's had no voice.
The trade off was less weight,= much less tone.
Goodbye Shuttle, hello Ampeg again.
