That you can have multiple options without taking up all the room in the house! With the Walkabout, Portabass, and the Fishman Pro Platinum, I have quite a few tone options. I'd like to pick up an EA iAmp350 at some point in the future to add the ultra clean option to the plate, as well (although the Walkabout can get an amazingly crisp clean tone...). Ideally, I'd have 3-4 single speaker cabs to go with them, ranging from ultra HiFi to thick, meaty goodness. How much fun is it to mix and match--Bergantino with Ampeg, iAmp with Aggie.... I'm lucky enough to play in two different groups with musicians who understand you don't have to make yourself deaf to make yourself heard so I can actually hear the differences in a band setting. At a certain point, all you hear is LOUD, and any color is lost. Of course, the tiny rigs will get surprisingly loud, too--best of both worlds! Sorry for the long post, but I just love my tiny rigs! OH, and a tip if you've managed to read this far--I wish I had thought of this before I bought my Walkabout bag for $60. I noticed the XBox carry case is the perfect size for the Walkabout/Portabass/iAmp/Traveler/etc size heads, and it's only $30, and readily available at your local Corporate Giant/Mom-n-Pop Mart-type-shops.
