Looking to upgrade my bass - Help required

[alexa3020]

I have 2001 Mexican Jazz Bass & I'm looking to upgrade. Unfortunately I cant fund a new bass purchase.

I'm looking at other ways to improve the sound. I'm thinking pickups.

I have some Amazon vouchers that only work at the .com site & not .co.uk - which means whatever I buy will have to be shipped from U.S - So pickups are nice and inexpensive to ship but I am fairly limited to what I can get.

I was hoping if someone could advise on the following at give an opinion as to whether they will improve the sound.

I like the look of the Aguillar AG 4J-60, but I'm basing that on.... well, nothing actually.

It would be great if someone in the know could give me their opinion - I play in a Rock band.

Cheers Guys

The original pups won't be so bad in a Fender. So rather than change those, how about a pre-amp?

Beware of buying from the states, anything over not a lot could / will land you with import duties and VAT.

Cheers guys,
Skidder unfortunately the sd pickups do not ship to U.K.
Grangur - do you mean a pedal or a new circuit in the.bass?
Bertbass - the import duties are listed at time of purchase, bit of a pain, but the vouchers have to be spent on the us site

I was actually thinking of a circuit in the bass. I saw this and thought it looks a good option:
