Yo!
Yeah i have an Egnater Mod 50! It's an amazing amp, but yeah, it's made by Bruce and Jeff in the USA, and costs quite a bit more than the tourmaster range, although they're still great amps :D
My Egnater has a voltage selector on the back, and you can can change the plug easily enough too. The best thing to do is post on the Egnater forum, ask if it has a voltage selector etc. Jeff will usually give you a answer pretty pronto, as with any other questions you might have
Get a Mod 50, or what Jonathan is getting, an M4!
