This is the onboard flash chip. It's basically like a little SD card, but soldered directly onto the PCB. These chips can
store a few megabytes. This doesn't seem like much but for most audio effects, you don't need hours of music. You
can store a couple minute's worth of compressed OGG on a 2M flash chip.
Headphone Output Type
All the way to the right is the headphone jack. This is for connecting to a pair of headphones or into a powered
speaker. It cannot drive an 8 ohm or 4 ohm speaker. Instead, an amplifier will have to be used (basically, just like your
phone or pocket MP3 player needs an external powered/amplified speaker)
The outputs are 'live level' (about 1Vpp) and have DC blocking capacitors so it can be connected to any kind of
amplifier.
