ead Posted May 11, 2013 Share Posted May 11, 2013 Could I ask for some advice on fault-finding the signal chain of a c. 1996 Spector bass please? Whilst the bass produces output from both pickups when plugged in, the output for a spector seems very low so I thought I'd work my way through the signal path to try to identify the fault. The treble end of the EQ seems a bit odd too. The pickups are branded SSD and measure c. 37 x 88mm which looks like the EMG-35 size if I'm not mistaken. If I disconnect the pickups what level of DC resistance should I expect to see if they are healthy? Are there any other tests that I could do? Thanks in advance.

MoonBassAlpha Posted May 12, 2013 Share Posted May 12, 2013 if the sound is equally low from both pickups, the problem is more likely to be doswnstream from there, either the volume pot, or the preamp itself (assuming you've eliminated the normal things like cable, amp etc.) Quote Link to comment Share on other sites More sharing options...
neepheid Posted May 12, 2013 Share Posted May 12, 2013 Assuming it's active - fresh battery installed? Just sayin'... Quote Link to comment Share on other sites More sharing options...
ead Posted May 12, 2013 Author Share Posted May 12, 2013 Thanks for the tips boys. The battery was the first thing I checked. After a bit more experimentation I think one of the volume pots may be the culprit, so I'll have to get the soldering iron out and start disconnecting and testing things.
