DVForge today is shipping its $49.95 JamPlug,
a tiny guitar amp you can plug into your guitar to listen through
headphones. The JamPlug isn't the first amp designed for use with
headphones, but as near as I can tell it's the smallest — by a lot.
This thing fits in your pocket and runs on AAA batteries, and the
manufacturer claims the patented device is the "smallest guitar amp in
the world." It ain't pretty, but it looks like a must-have practice accessory.

We've scheduled a review; stay tuned.

Update: Musicthing has found this fantastic LED guitar pick — that makes two guitar player stocking stuffers. Now for us keyboardists . . .
