This is quite cute - Vox are doing a range of little headphone amps - one based on the AC30 with top boost, 'Classic Rock' based on a Marshall and 'Metal' based presumably on a Mesa Boogie. The circuitry is analog and runs on 2xAAA batteries. No idea how they sound, but they're quite nice looking. Disappointingly, they all look like AC30s, just with different stickers. £35, further bumpf at Vox website.
Incididentally, what is it with copywriters for music gear companies? They claim: "amPlug perfectly reproduces the complex and warm distortion that is distinctive of a vacuum tube... amPlug delivers full-fledged amp sound that will revolutionize your guitar playing." Both of these claims are clearly lies (the 'perfectly reproduces' and the 'revolutionize your guitar playing' bits). What was wrong with: "Sounds OK, looks OK, costs £35, what's not to like?"
AND ANOTHER THING: If Vox are going to put a Union Jack on their homepage and a London bus on their news page (despite having being owned by Korg since 1992), they should probably learn how to spell 'revolutionise' properly.
