[quote name='thisnameistaken' post='677437' date='Dec 8 2009, 02:38 AM']You're spoilt for choice, basically. But avoid super-budget names like Vintage, Harley Benton, Stagg, etc. I don't know where they're building those but they aren't pleasant to play.[/quote]
I've played a few really nice Vintage basses and there was a killer Stagg Jazz in my local Crack Converters, the headstock logo is horrible though! Probably the exception rather than the rule but those brands do produce some good P and J variants. Similarly the Aria basses are generally well built and good players
Regarding a good 1st bass for under £300 i'd go with what everyone says and look at the Squier CV series, also have a good look at the market section on here as there's some silly-good bargains pretty much every day!
