Alright, it's that time. Upgrad'n time. My current (extremely beginner) rig is a Squier Short Scale Jaguar going into an Ampeg BA-108. I am the on-call bassist in my friend group, which means I end up playing songs by Nirvana, the Foo Fighters, America, the Beatles, Two Door Cinema Club, and many more, from a wide range of genres. I have $800. I have almost no way to buy used. What do you suggest I do? Addendum: I'm also looking at the Blacktop Jazz bass, but that will run me $500.
