Hi all. I am loving my "new to me" Spector Euro that I bought this summer. I have noticed though that the bass will completely kill a 9v battery within a few weeks even if not plugged in. I have gone through 3 batteries already and the bass has really not been played much. Its like the Tone Pump pre amp is always on no matter what. Anyone have any ideas? I understand the preamp was removed by the previous owner and re installed when he sold it but everything looks clean and original inside.

99% sure the problem is this:
The Ground "Black wire" from the Battery and the "Black wire" from the Tonepump are on the wrong place on the input jack. If you swap their places on the input jack it will solve the problem.
When it's wired incorrectly like this, it will work and sound normal but it's like leaving the jack plugged in 24/7.
Which kills the battery every few weeks.
:scowl:
Maybe talk the price down for that stacked knob.
) My bass is a NS2A with MM114 pre. I run my blend in the middle and treble 50%, bass around 65%
