Sjael Posted March 17, 2010 Share Posted March 17, 2010 If passive mode works fine then it's more likely than not something to do with the preamp(s?[i don't know if EpiActives have individual preamps in the pickups or single external one.]) First thing I'd do is try a new battery. Active pickups can do some peculiar things when their battery is low (with my EMGs, for example, the open A string becomes strangely loud, not the A note in general, just that one position.) Failing that, I'd send it back under warranty (assuming you bought it new.) Link to comment Share on other sites More sharing options...
manosXVIII Posted March 17, 2010 Author Share Posted March 17, 2010 i tried a new battery... still the same... also tried different amps.. still the same... the thing is that after playing with force (as in the sample) everything is fine until i unplug....:) thanks for the reply...

If you have already tried another 9v battery.. you have some kind of connection problem inside. That sounds like distortion from some kind of intermittent problem. Since some of the notes played sounded normal, it seems to be only certain frequencies (or amplitudes of those frequencies affected). Just listening to the distortion indicates either a poor connection or a power problem. Here's some suggestions to investigate. Could be the jack that switches the battery on/off..those are not as reliable as the standard switchcraft jacks because the contacts are small and tend to oxidize. OR some kind of connection between the p_ups and preamp...are the p_ups connected through connectors? Intermittent volume pot from the vibration of the guitar body.

manosXVIII Posted March 18, 2010 Author Share Posted March 18, 2010 but if i have a connection problem.. wouldn't the problem be permanent??? my sound is fine after playing with force..... it is like when i do that,, it "wakens" the pickups...

These are very common intermittent problems. The signal is very tiny ( few millivolts at best) and any connection with corrosion, "dirt/smoke contamination" or loose fitting can cause this...a cold solder joint on a ground connection etc. Link to comment Share on other sites More sharing options...
