I went through all this years ago and spent a ton of money on garbage. Seems to me you’re starting out sort of thing. What I would do is rent a few loud bass amp combos or a head and cabinet. Just because it’s 300-500 watts(depending on the amp) you don’t have to crank it. What you need or should do is see what your bass can do with a massive amount of clean headroom. Get the clean thump of your bass first and get used to it. Then jazz it up with your pedals and accessories. If something sounds like junk you can rule out your bass and amp you choose because you should be familiar with it.
