[size=4]my 2 cts: it depends...[/size]
[size=4]used, there is a lot of gear that really is high end, set up well and sounds and plays great available for a lot under [color=#2A2A2A][font=Tahoma,Verdana,Arial,sans-serif]£[/font][/color]1000[color=#2A2A2A][font=Tahoma,Verdana,Arial,sans-serif].[/font][/color][/size]
[size=4][color=#2A2A2A][font=Tahoma,Verdana,Arial,sans-serif]I play bass professionally (that means that usually I get paid for gigs) and my most expensive instrument is the seibass I just bought used for a bit over £1000[/font][/color][/size]. this got all I have ever expected from a 5-string.
my 4-strings have been [b]a lot[/b] cheaper, the most rare and expensive one was 1000€ but it is my main player in my band and I probably will never find a better only a more expensive one.
it is more about what you do with what you have.
playability is the 1st secret, tone the 2nd.
on every cheap bass both can be achieved with a small investment.
but without a vision even the most expensive instrument won't take you anywhere.
