Hi Abi, hope you're keeping well, and getting to know your bass. π€
Regarding home recording: As the comments above, the Scarlett seems to be a smart choice. I'll be looking for one of those myself sometime... my cheap Behringer USB mixer just about works as an interface, but its frustratingly tricky to use.
Also as said above, the B3n is great for making strange / cool / funky noises, but it doesn't work as an audio interface.
Nice work on the sax by the way -- you have a great tone! π
