So my old Cort Artisan A5 5-string bass seems to have very low output. I'm primarily a guitar player so I haven't even got a proper bass amp, have been running my bass through Guitar Rig 2 demo on the computer. Anyway, compared to my guitars it seems that the bass has very low output. It barely even registers on the output meters when plugged into my soundcard's line-in. The guitars have no problems with output when plugged into the computer so it's not just a case of low line level signal. It has two Mighty Mite pickups and an active preamp with volume, balance and high and low boost/cut pots. Pickup height is about 3mm from the strings. I tried swapping the battery in the bass but that didn't help. Couldn't see anything wrong with the preamp but then again I'm no electronics wiz. What could I do to find out where the problem lies? I can post pics if needed.
