After the first night with the Marshall at band volumes, the JF Brahma and RM100KH just sound bigger. The low end is more full and tighter. Has more of a 3D type of tone for lack of a better term compared to the Marshall.
Could be because the high end in the Marshall sits different in a mix from what I am used to with the Brahma which sounds more even across the range. With the Marshall the low end is not as present. The Marshall is pretty good in it's own way so I will spend some more time with it.
