Hello, I need some help choosing the better amp, my choice is between Cort MX-15R and Laney LX12, The Cort MX-15R comes with the reverb option, where as the LX12 is more expensive and suggested to me by someone I know. There's also the orange Crush 12L 12W amplifier as well?, Is it worth buying the Cort MX-15R just because of the reverb option? also which of these suits best for playing heavy metal music? I don't know much about electric guitar amps as I've played acoustic for the most part. I'm hoping the guitar gods in this forum would help me out. Thank you. I've also noticed that some amps have 'Mp3 in support' or something, could someone explain?
