While I like the sound of the ABM with the 4x10 cab a lot, my heart goes BOOOOM with the additional 2x10. Nothing beats a 6x10 or 8x10 bass rig with an old fashioned transformer head! 😍
2 kg amps suck tonewise and every skilled sound guy will tell you. But it is like with vinyl... young people that never heard a record on a good payer will believe, mp3 is the best possible audio format.
But I just can't compromise, I know the tonal difference and can tell within seconds (in terms of listening to a bass rig)
