This highly versatile Boss Dual Cube Bass LX (new $329) portable, battery powered bass amp with optional bluetooth adapter (new $50) lets you play bass anywhere. Runs off of AA batteries as well as AC mains, but because the power supply is 9V, I’ve added a small rechargeable battery bank. I’ve run this setup for over 4 hours and never run out of juice. While it certainly won’t put out chest-thumping bass, it will keep up with multiple acoustic guitars, mandos, ukes, harmonicas, and even a banjo or two. It has XLR outs for times when you have PA support. Also has tons of effects (chorus, reverb, compressor, distortion, amp modeling, etc), customizable with an app, and even a looper and drum machine for solo practice. With the bluetooth adapter it doubles as a bluetooth speaker letting you play along or just listen to music. Includes AC power supply and amp cover. If you want the rechargeable 9V battery, I’ll include it for an extra $35 (new they are $50+).
Unit is in very good condition. Some minor scuffs from usage, with the worst shown in the photo of the corner.

I purchased this used about a year ago. While it has been great, my needs have changed.
