Manwithvan Posted September 5, 2016 Share Posted September 5, 2016 Can anyone offer some advice on this technical problem? My Spectorcore 4 fretless has a much lower response from the A string. I've considered the string itself, break angle etc, but the fact is that simply tapping the A-string saddle gives a lower output than from the rest. The volume difference is quite significant, so any ideas are gratefully received. Quote Link to comment Share on other sites More sharing options...
ikay Posted September 6, 2016 Share Posted September 6, 2016 Sounds like a duff piezo element on the A saddle to me. The Spectorcore uses a Fishman Powerbridge. I think all the piezo elements feed into a circuit board on the underside of the bridge which combines the signal into a single output (coax cable). No adjustment for individual saddle outputs as far as I can see but that would be the first thing to check. Changing a single element would require connections on the board to be desoldered and resoldered which may be tricky. Back to a Spectorcore dealer or a tech for repair is probably the best bet. If you feel like tackling it yourself then try contacting Fishman to see if they can supply a new piezo element ([url="http://www.fishman.com/support/contactsupport.php"]http://www.fishman.com/support/contactsupport.php[/url]).

luckydog Posted September 6, 2016 Share Posted September 6, 2016 Without knowing that specific arrangement, perhaps the transducer has slipped, or isn't tightly coupled anymore ? LD Quote Link to comment Share on other sites More sharing options...
steve-bbb Posted September 9, 2016 Share Posted September 9, 2016 maybe something like this? http://www.east-uk.com/index.php/bass/piezo-magnetic-mixer/mpm-01.html Quote Link to comment Share on other sites More sharing options...
