I,ve got this little B.B. Blaster 10watt jobby.
You flick the "Juice On" switch, plug the lead into the hole marked "Enter", twiddle the three knobs marked "Beef", "Tweak" and "Enjoy"!
There's also a red button marked "ZAP!" :eek:

I've also got a couple of micro-amps, a Marshall and a Fender, which are great for the great outdoors, where power isn't available.
