Hey there fellas. I'm looking at purchasing a markbass 15" cab. I'm inbetween the cmd 151p( 899 on sale) and the jeff berlin model( 875 b stock return) is there a significant difference between them besides the piezo? Has anyone A/B them. I am set on one of those 2 just trying to figure which to go with. Just need a stand alone combo. I am also looking at purchasing my buddy's mb 102hf cabinet in the future to pair up with the 15 combo. Just would like ur input as far as which 15 inch combo. Thanks!
