Hey, it only weighs 46 lbs...that shouldn't bother anyone used to lugging a G70.

Guitar amps do not amplify keyboards very well, especially arrangers, even amps designed for acoustic guitar, which have a slightly broader frequency range than those for electric instruments.

Some people play synthesizers through guitar amps, but it is mainly for an effect or a certain tone.

I used to play "lead guitar" in one band I played in, using a highly modded guitar patch on my DX7MkII and a Fender Twin, plus some effects pedals.

I must say, the amp in question looks very cool.
