Hi Andy! Sounds good, glad you’re getting your bass setup early on too. 
Hey Boz, I have not, that thing looks freaking crazy!
Would be nice for looping I imagine…
Hey Matias! Anything in particular you’re looking for? I know Gio posted a little something a while back, let me find it… here it is - Jam Tracks / Improv. Tracks - Share your bassline
Also all the lessons on Bass Buzz have a playalong component, so there’s backing tracks you can play around with there (I usually include a version without an existing bass track so you can experiment), either in the free section (like the Bass Basics playalongs) or more in-depth in the Beginner to Badass course.
