Warwick Streamer II preamp issue

[carlitos71]

Hi all

I have a 18yo Warwick Streamer II and have a little technical issue.

The preamp when engaged makes a bad noise (sounds like muffled clapping...). A fellow bass player mentioned it could be preamp the wiring. I am considering changing the pups.

Does anybody know any good tech in London (near West London, W14 preferbly) that could please help me?

Any suggestions much appreciated

Thanks

Carlos
