hey guys. i'm not sure if i should get a Marshall AD50 which is around 400$ some of my friends told me that i should jsut save up for another guitar but i'm not sure if i should buy it. i need a amp with a mike jack for singing for my band but i'm not sure. are there any other good amps out there for under 400$ that has a mic. jack and a instrument and EQ? thanks a bunch.
