You need a portable amp bro?
There's many others you should consider, like the Marshall MS-2 or MS-4, which are clip-on mics..
Small enough to keep in your guitar bag's pocket!
Check out the mini amps offered by Fender, Danelectro and Orange too!
Haha.. I've tried the ms-2 and ms-4.. The 1 watt power seems a little too light for me.. I don't really like the built in OD too.. So the next best option would be a 10 watt..
