Hello, I've played bass for 3 years with my brother's bass, but now I don't have any access to it anymore and I want to start playing again.

My question is: Which bass guitars have the best price-quality ratio for a budget of 600€?

Pickups, tuners, bridge, electronics... ther's a few things you can upgrade. John Swift (another forum member) is big on putting John East preamps into cheaper Fenders (or Squiers, I can't remember which), for example. I don't think he even swaps out the pups. He's had more expensive basses in his time, but thinks that with the John East, a cheaper bass is a great way to go.
I'd go used... you're in Warwick Corvette standard or even an older/slightly scarred AM Standard Fender territory there.
