Has anyone been able to compare the two of these amps? I currently have the Amp Three, which has a low end and a presence on stage that I really love for how small it is—but I’m looking into finding a Bass Cube 2 because I can use the two separate channels to double on upright bass and electric, and it seems like it has a Speakon output for a passive extension speaker (right?). Questions: Is the Bass Cube 2 as loud, girthy and present as the Amp Three? It looks like the Bass Cube 2 has a Speakon output for a passive extension speaker, is this true? Thank you so much for the help!
