Hi guys, I have the money to buy a new amp and cab. I have seen the Randall Diavlo RD100H and love it. My only hold up is I have seen two versions. The RD100H and the RD100. Can anyone please tell me the differences between the two? Also, let's compare the Diavlo to an Engl E636 Extreme aggression head. which is based on a fireball 100. I can buy either one, but the Engl will come with no cab as the head is very expensive. I am working with a Mesa Triple Rectifier and standard 4X12 Mesa Rectifier cab. which amp head will probably be the tightest without an overdrive Pedal pushing the amps compared to my triple rectifier. Any insight is helpful.
