I always eschewed the combo bass amps as underpowered, un-fulfilling sound quality and just plain jingus in general. No matter what options are included they always just can't cut it. Feeling that the full power of a good 2x15 cab can only really reproduce the Bass in all it's glory, and move alittle air too ! throw in a 2 x12 cab crossover'd or biamped is even better. But a single driver just never seems enough. btw: i do not play at super high volumes or play hard driving metal, So just blasting away at full volume is not where I am coming from. Your Thoughts ?
