In bass world, there has been a clear and steady move for some years now away from amplifiers, in the sense of hefty, tube-, or solid state-powered boxes that you lug to the studio or stage and plug your instrument into. 

Here at Bass Player, we’ve witnessed the rise of Class D heads, then pedal-sized bass amps, then amp-modeling units such as the Kemper, and of course amp-simulating software in a digital audio workstation or laptop. There have been a few attempts at iOS or Android-based amp apps on phones and tablets, too, with varying degrees of efficiency and take-up by the bass community.
