Will it work fine? My amp is a Randall RM100 head (100 watts) and my cabinet is a ported Genz Benz G-Flex 2x12 which is very dark sounding and puts massive lows for a 2x12 guitar cabinet. The cab is rated at 150 watts (75w x 2). So my question is will it be fine when I'm playing bass through it? I am concerned about the tubes and the speakers mainly. Oh and I'm not going to use this set-up in any performances at all, just for writing songs (and for fun mostly ).
