I never write product reviews, but this is worth an awesome review. I tried the hifonics Brutus brx 2400 and it was awesome but the amp depth was really deep. The gain on hifonics was up to 75% and I really didn’t like for level to have to be that high. I am familia with Big Bang dating back to early 2000s, but I was skeptical of newer model. I consider buying a refurb of the bb2400.1 because I know it’s awesome, but this successor is just as awesome or (awesomer). I have it on American 2 American bass xr12d4 and they hit deep like my lanzar optidrive15. If you are hesitant, don’t be I promise you will not be disappointed. Gain right at 50% and it doesn’t even get warm
