Couldn't find any reviews of it on bass on Youtube but did watch a comparison video, this versus the Boss. Boss wins out slightly on sound quality and VR gimmick, Spark NEO on comfort, the app, and the fact it uses USB-C not Micro-USB to charge. I would also point out that as the Boss has a TRS dongle (I assume that's for charging), that probably means that certain active basses will have issues with it - the ones that don't follow the convention of battery negative to ring, ground to sleeve.
