Hi guys i want to buy a new bass with 5-strings and my budget is around 400€-500€.I'm searching at thomman
And i'm between this 3 basses:

1.Traben Chaos Attack 5

2.Ibanez Sr375E

3.Ibanez PIB3

The 3rd bass if i buy it i will change the factory tuning in standar BEADG

Of course if you have any other suggestions tell me because i dont have too much experience on that point
Traben made some good basses, but I haven't heard anything from them in a very long time. Even their website seems a little finicky. If you get one, just be warned that the company might be in a transitional phase. But they made some fine instruments. The Chaos Attack wasn't one of their higher-end models, but it played and sounded very good and came stock with Rockfield pickups.

Of the two Ibanez basses you've listed, I think your best bet is the SR375. The Peter Iwers Signature is a good bass, but the SR is tried and true.

A used Maruszczyk might be in budget if you know where to look.
