krazy_olie Posted August 23, 2011 Share Posted August 23, 2011 I think it's always been there and just didn't notice due to using a 15" (or a t least a number of years) but there is a very significant hiss coming from the bass (L2000 tribute) when in active, and it's more prevalent when it's in "active with treble boost" mode. No problems with passive that I can notice. Weirdly it is the same volume regardless of all other controls, volume, pick-up switches, treble etc... Sound like a problem with the preamp? It needs a set-up anyway but seeing as I usually use it in passive mode anyway I don't really want to fork out loads of cash to fix it. My guess would be a capacitor or some component on the preamp board itself like the op amp but not really able to fiddle with that. P.s I have tried a fresh battery. Thanks in advance!

krazy_olie Posted August 24, 2011 Author Share Posted August 24, 2011 cheers, i''ll have a look. Can see from sig you have one, guess you don't have the same problem? Quote Link to comment Share on other sites More sharing options...
jezzaboy Posted August 25, 2011 Share Posted August 25, 2011 I have never noticed any buzzing but then again I use it in passive mode most of the time. I`m pretty sure that all the active circut does is boost the signal as the tone controls are passive all the time, but don`t quote me on that Jez Quote Link to comment Share on other sites More sharing options...
ThomBassmonkey Posted August 26, 2011 Share Posted August 26, 2011 Have you tried a different lead? Different amp? All kinds of things can interact to make hiss, it'll probably start with your pre, but your lead or amp could be making it worse. Quote Link to comment Share on other sites More sharing options...
