I'm surprised that no one in this thread has mentioned the Fender Mustang Micro. Or have I mis-read the original intent? Perhaps I'm focused in that direction because I've considered buying one for myself. But since I live alone, it doesn't really fit a need.
Still, the Mustang Micro gets rave reviews. Plug it in to your guitar, plug in a pair of earphones (1/8" or 3.5mm) and off you go. Here is a list of features straight from Fender:
- All-in-one personal headphone amplifier with onboard DSP
- 12 amp models for a wide range of clean and dirty tones
- 12 effect combinations with parameter modify control
- Adjustable EQ
- Convenient volume control
- Bluetooth audio streaming with audio/video sync for playing along in real time
- Rechargeable lithium ion battery (charged via USB)
- 4 hours of continuous play time
- Rotating input plug for compatibility with most guitars and basses
- USB interface for recording output and firmware updates
