I’d still tout the discontinued Warwick Std range as the best budget basses out there, and at around £200 for a used 4 string Streamer Std, they’re amazing value IMO. A German built Warwick with the ovangkol neck that gets used on the high end bolt-on Warwicks for £200 – how can you possibly go wrong with that? Mine feels better than a few Thumb BOs I’ve tried, and also better than some FNA Streamers I’ve played as well. Quite weighty though…
I’ve also played a few MIM Jazz basses that I thought were fantastic. It’s hit and miss with anything mass produced though, and I think it’s more likely to be ‘miss’ more often than ‘hit’ with cheaply mass produced instruments, but there are gems out there.
