Pickup/ preamp for Ibanez AEB10 bass

[gimmeagig]

I have a Ibanez AEB10 4 string acoustic bass guitar and the pickup is broken. It is intermittent. The pickup shorts out. Sometimes all strings are dead sometimes just the two outside ones. The preamp is fine. I did a search but I can't seem to find a replacement.The bass plays really well so I don't want to give up on it. Is there a replacement or maybe even an upgrade available for it?

Hello.
My problem is that the preamp died. I haven't found a replacement for it.
Could you solve your problem? Any help is good for me.

Amazon. I don't know how good they are and if they fit. You may have to make some adjustments but there are a lot of them available.
