Hello everyone. Since I moved to my dorm, I finally got bunch of free time to practice my bass. Problem? I dont have a small amp to play with... I am looking for a small, portable bass amp that is mainly geared towards practice. when I say small/portable, i am talking about... smaller/lighter than Roland cube. I remember seeing one of those 'cigarret box sized' amp, where you plug in your headphone to play. any suggestion? p.s. price is a great factor in this matter too. thank you.
