Hi New to this site so please bare with me. I have a Pangbourne fretless bass which I had made for me back in the 80's , have not used for some time and looking to start to using again however the actives are not working frying egg white noise. sounds. I have changed the battery and works on passive when switched over. Switch has been cleaned. Currently with someone who is looking at but thinks the actives have gone, hence the reason for a reach out if anyone knows if I can get a replacement system. It Is based on Bass, Middle, Top setup. Would be awesome if someone can advise where to obtain new actives unit. Thanks Nick
