Great little amp, watch for power supply
Ordering from the UK, I couldn't use this immediately - it shipped with a European power supply. Running it through a travel adaptor worked, but introduced a horrendous buzz, as it couldn't earth properly.
A C5 Power Supply (available from Amazon and the like for about £1.50) solves the problem entirely though, leaving this as a great little piece of kit. Small, deceptively powerful, and with bizarrely good stereo performance for its size. For an onboard effect on a tiny little amp, the reverb sounds HUGE, and very realistic.
