Hello!
Yip... I've had a torrid time trying to choose between this and the Walkabout. I've been tearing my hair out (as any of my Facebook BC pals will attest - I've had one for sale, then the other, then changed my mind...).
The Aggie is far more practical (higher output, mute, post / pre DI), and kicks like a mule, but for the gigs I've got coming up the sound guys are used to my Walkabout and do great things with it. I've realised the tubes in the Walkabout are just more [i]me[/i].
It's been a pleasure A/B-ing them for the last six weeks or so, mind.
