These Johnson Mini Amplifiers really pack a punch for the size! You are free to take it anywhere you like because it is able to operate on a 9V battery. The amp can also plug into the wall with an AC adapter. The JA-004 is small enough to fit inside most gig bags, and hard cases, and weighs only 1.75 Lbs. [−] less
